Which AI video upscaler is best this year? That depends on where you edit. Desktop AI video upscaling software is a good fit for 4K output, larger files, and repeat projects; mobile apps offer convenient fixes for clips on your phone; and browser-based upscalers are useful when you do not want to install anything. This guide compares 11 AI video upscaler tools across desktop, mobile, and online use, including their strengths, trade-offs, and free-access limits.
Quick answer: UniConverter is our all-in-one Windows/Mac pick for creators who want AI upscaling plus batch video workflows; Topaz Video is a specialist option for detailed restoration; Wink makes mobile enhancement approachable; Video2X is a genuinely free open-source desktop choice; and TensorPix is a browser-based option with recurring free credits. These are use-case recommendations based on public product information—not a controlled quality benchmark.
- For Windows and Mac: prioritize model choice, realistic previews, export resolution, hardware compatibility, and batch processing.
- For iPhone and Android: distinguish genuine AI enhancement from simply exporting a clip at 4K.
- For free online AI upscaling: “free to start” may still involve credits, watermarks, short previews, or limited exports.
- For old or compressed clips: AI can infer convincing detail, but cannot guarantee recovery of information the camera never recorded.
Best AI Video Upscalers at a Glance: Our Quick Picks
These recommendations focus on different needs rather than pretending that one product wins every test. If you want a video upscaler for PC or Mac, start with desktop software; for short social clips, an app may be more convenient.

Part 1. Best AI Video Upscaling Software for Windows & Mac
For longer footage, many files, or repeat 4K projects, desktop AI video upscaling software generally offers the most complete workflow. If your main goal is to find software to upscale video rather than compare every platform, explore our dedicated AI video upscaling software for Windows and Mac page.
Wondershare UniConverter — Best All-in-One Desktop AI Video Upscaler
Best for: Creators who need AI video upscaling plus format conversion and batch processing
UniConverter combines video upscaling with formats, enhancement tools, and a multi-video queue. The desktop AI Video Enhancer includes Standard, Ultra (Gen AI), and Topaz Ultra (Gen AI) options. Supported Ultra settings include 2× and 4× scaling, while Topaz Ultra provides a dedicated 4K target. You can preview a sample, import folders, and enhance more than one video without rebuilding a project for every clip. For creators who also convert and compress content, the broader UniConverter toolkit is a practical advantage.
Not every enhancement model offers the same output choices, and some generative jobs rely on cloud processing and AI credits. Upscaling raises output resolution and can infer new detail; it cannot reconstruct the exact original information that was missing.
Key AI upscaling features
- AI video quality enhancement with dedicated 2× / 4× options in supported modes
- 4K target output in a dedicated enhancement mode
- Preview the effect before full export
- Folder import, multiple-video queue and batch export

Choose the right AI enhancement mode, preview the result, and export on Windows or Mac. Advanced models may use AI credits.
Topaz Video — Best for Professional Detail Restoration
Best for: Filmmakers and archive editors who prioritize model control
Topaz Video is a dedicated AI video enhancement application for editors who need to inspect texture, reduce noise, restore focus, or improve old footage. Its models target upscaling, stabilization, interpolation, and scene-specific restoration instead of trying to replace a complete nonlinear editor. It is especially relevant when fine detail matters more than a fast beginner workflow.
Its depth is also the trade-off: processing can be resource-intensive, and selecting an appropriate model takes more effort. If you mainly need basic cleanup for social clips, a simpler video upscaling program may be easier.
Key AI upscaling features
- AI upscale and archival restoration models
- Video denoising and frame interpolation
- Tools for focus and stabilization
HitPaw VikPea — Best for Beginner-Friendly AI Upscaling
Best for: New users who want guided desktop models and previews
HitPaw VikPea offers a guided AI video enhancer for blurry, compressed, and low-resolution clips. It promotes 4K/8K enlargement, AI denoising, and content-oriented restoration models for everything from portraits to AI-generated footage. Its preview workflow helps casual creators evaluate a change without immediately committing to a full export.
Check whether a specific feature runs on your own hardware or via a separate cloud-acceleration service: some acceleration options use additional credits.
Key AI upscaling features
- AI video upscaling to 4K/8K in supported workflows
- Denoise, face enhancement and restoration tools
- Model preview and optional cloud acceleration
AVCLabs Video Enhancer AI — Best for Old and Damaged Footage
Best for: Home video restoration, denoising, and face refinement
AVCLabs Video Enhancer AI is a desktop option with tools for upscaling SD or HD video to 1080p, 4K, or 8K, reducing noise, refining faces, and colorizing old black-and-white material. Its all-in-one restoration feature set makes it a sensible candidate for home movies and archived clips that need more than a simple resize.
The app relies on compatible hardware for responsive performance. Check its GPU requirements before downloading, especially on older Windows PCs.
Key AI upscaling features
- AI video upscaling and face enhancement
- Colorization, denoising and stabilization
- Local desktop workflow on supported systems
Video2X — Best Free Open-Source Video Upscaling Program
Best for: Technically comfortable users seeking free local upscaling
Video2X is an open-source AI upscaling and frame interpolation project rather than a commercial enhancement suite. Its current generation supports Anime4K, Real-ESRGAN, Real-CUGAN and RIFE workflows, with a Windows GUI and support for Linux. For people searching for the best local video upscaler without subscription costs, it is an important alternative.
Because Video2X relies on compatible hardware and technical settings, it is less immediately approachable than click-and-export commercial tools. Output size depends on the selected algorithm and upscale factor, rather than a guaranteed 4K result for every file.
Key AI upscaling features
- Real-ESRGAN / Real-CUGAN / Anime4K pipelines
- RIFE frame interpolation
- Windows GUI with Vulkan-based acceleration
Part 2. Best AI Video Upscaler Apps for iPhone & Android
The best AI video upscaling app should be easy to use on a phone and should improve visual detail—not merely save an existing video in a bigger container. App-store availability, purchase terms, and models differ by region and version. For more options beyond upscaling, see our roundup of best apps to improve video quality.
Wink — Best for Quick Mobile Super Resolution
Best for: One-tap portrait, social and family-video enhancement
Wink, from Meitu, targets creators who want to brighten, unblur, and improve short clips without moving to a desktop editor. Its mobile feature set includes HD enhancement, 4K Super Resolution, face retouching, and old-video restoration. That makes it a practical choice for social videos, family clips, and phone footage where convenience matters most.
Installing the app is free, but its VIP offering covers premium models and expanded 4K use. Do not interpret the free app listing as a promise of unlimited free 4K exports.
Key AI upscaling features
- AI HD enhancement and 4K Super Resolution
- Portrait repair and video unblur tools
- Phone-first editing and creative filters
HitPaw VikPea App — Best for Dedicated 4K Mobile Enlargement
Best for: Phone and tablet users wanting a dedicated 4K enlargement mode
HitPaw VikPea App brings familiar AI enhancement actions to mobile, with 4K Enlarge and Face Enhance modes listed in its iOS product description. Instead of using a complete desktop workflow, you can select a clip and try a targeted enhancement on the device you already use.
Mobile versions can have different models and in-app purchases than the desktop VikPea software. Confirm the app listing for your operating system and region before assuming feature parity.
Key AI upscaling features
- Mobile 4K Enlarge feature
- AI face enhancement and old-video restoration
- Before-and-after viewing
PowerDirector App — Best for AI Enhancement Plus Mobile Editing
Best for: Creators who want upscaling and timeline editing on mobile
PowerDirector is a fuller mobile video editor with AI enhancement tools as part of a broader timeline workflow. Its mobile app listings describe sharper video, 4K exports, stabilization and effects; CyberLink also provides an app-specific tutorial for an AI Video Upscaler workflow. It is a natural fit when you need to sharpen a clip and then add captions, music, transitions, or other edits in the same app.
Be careful comparing its 4K export capability with dedicated super-resolution: those are not synonymous. Some features and exports depend on app version, hardware, subscription, or credits.
Key AI upscaling features
- AI video enhancement / upscaler in supported mobile versions
- Editing, captions, transitions, stabilization
- 4K export available on supported devices
Part 3. Best Free Online AI Video Upscalers and Enhancers
Searching for a free AI video upscaler online? Browser tools remove the need for software installation but usually have trade-offs involving file limits, credits, upload time or paid higher-resolution export. We include one fast online restoration tool as a lighter alternative, but distinguish it from tools advertising true resolution enlargement.
UniConverter Online — Best for Quick Free Quality Restoration
Best for: One-off online restoration before deciding on desktop software
UniConverter Online AI Video Enhancer is designed for short, straightforward video quality improvements in a browser. It lets you upload a clip and try an online quality-restoration model without installing desktop software. For occasional blurry footage, this can be a convenient first look at the effect of AI repair.
Important distinction: the current online workflow is not equivalent to the UniConverter desktop app's full video upscaling model selection or fixed 4K output. Users who specifically need 2×/4× scaling, folder import and more output control should use desktop.
Key AI upscaling features
- Browser-based video quality restoration
- Simple upload, preview and export
- Desktop upgrade path for richer upscaling
TensorPix — Best for Cloud Upscaling with Free Starter Credits
Best for: Browser-based AI upscaling without a powerful local PC
TensorPix is an online video enhancer with AI filters for upscaling, denoising, and other restoration jobs. It is suitable when you prefer to process clips in a browser instead of installing a demanding desktop application. The free tier offers starter and recurring login credits, which can help you test whether a source clip benefits from AI enlargement.
Its public plan table sets the free tier's maximum input resolution at 720p, whereas paid plans accept inputs up to 4K. That is not the same as saying free users receive unlimited 4K exports, so confirm the export options for your intended job.
Key AI upscaling features
- Cloud AI Upscale and denoise filters
- Recurring login credit model
- High-resolution processing on eligible paid tiers
Vmake AI — Best for Automatic Online Video Enhancement
Best for: Web users who prefer automated enhancement presets
Vmake AI offers a browser-based video enhancer aimed at making soft, noisy or compressed clips look cleaner with minimal setup. Its current website promotes selectable 2K, 4K and 8K enhancement targets, making it worth checking for short social footage and AI-generated video cleanup.
However, the official pricing page lists the dedicated Video Upscaler feature in paid tiers rather than the free tier. Treat the free experience as a limited trial of available functions, not proof that every advertised resolution can be exported free.
Key AI upscaling features
- Automatic online AI video enhancement
- Advertised 2K / 4K / 8K target options
- Web upload and before/after flow
How to Choose the Best AI Video Upscaler for Your Footage
There is no single best tool for everyone. Pick according to what your source video actually lacks and how you plan to deliver it.
| If you need… | Prioritize… | Why it matters |
|---|---|---|
| Old 480p/720p recordings on a 4K screen | True AI upscaling and preview | A higher resolution alone does not recover texture. |
| Face-focused clips | Face models and temporal consistency | Look for unnatural changes around eyes, hair and mouths. |
| Many videos each week | Batch queue and predictable credits | Reduces manual repetition and hidden cost. |
| Low-spec PC | Cloud/browser tools | Processing is done remotely, subject to upload terms. |
| Strictly free local editing | Open-source software | Trade setup time and hardware configuration for no subscription. |
| Private or sensitive footage | Documented local processing | Never assume every AI model uses local processing. |
For more no-cost options, compare our separate guide to free video upscalers. Keep in mind that simulated texture and AI-generated details are not the same as original camera information.
How to Upscale a Video with UniConverter on Windows or Mac
If you decide you want a downloadable AI video upscaler, UniConverter offers a straightforward workflow without switching between several programs.
-
Import a video or folder. Launch UniConverter and open Video Enhancer, then add your clip or multiple files.
-
Pick an AI enhancement mode and output. Select a general quality mode or a more detailed model, then choose available upscale options such as 2×, 4× or a 4K target when supported.
-
Preview and export. Inspect fine details and motion in the preview, review the estimated credits, choose the destination and export your finished video. Batch export is available for queued files.
For footage with prominent faces, check whether a face enhancement mode produces a more natural result than a general model. Always keep your original clip, especially for irreplaceable family videos.

FAQs About the Best AI Video Upscalers
What is the best AI video upscaler in 2026?
For a mixed editing workflow, UniConverter is a practical Windows/Mac choice; Topaz Video targets specialist restoration; Wink focuses on mobile convenience; Video2X is a free, open-source local option; and TensorPix offers cloud AI upscaling with starter credits. The best choice depends on your footage and device.
What is the best free AI video upscaler?
For a genuinely free local program, Video2X is an open-source option with hardware requirements. TensorPix offers free starter credits online, while many commercial tools provide a limited trial rather than unlimited free exports.
Can AI video upscaling software turn 720p into 4K?
Yes, supported AI models can produce a 4K output from lower-resolution sources. Actual visible improvement depends on the original footage, the AI model and settings; a 4K-sized export cannot guarantee real lost detail is recovered.
Is AI video upscaling better on desktop or online?
Desktop tools can offer richer model selection and batch workflows, while online tools avoid installation and local hardware demands. Cloud services may impose upload, privacy, credit, or file size restrictions.
Which AI video upscaler app works on iPhone and Android?
Wink and PowerDirector both have iOS and Android listings with video enhancement functionality. VikPea also has an iOS app with 4K enlargement; check regional availability and feature differences before installing.
What is the difference between upscaling and enhancing a video?
Upscaling increases output pixel dimensions. Enhancement improves perceived quality through methods such as denoising, sharpening, face repair or motion smoothing, which may or may not increase resolution.
What is the best local video upscaler?
Video2X is a strong free open-source candidate for technical users on Windows or Linux; Topaz Video is a commercial option for detailed workstation-based restoration. Some other products mix local and cloud modes, so verify the specific model.
Can an AI video upscaler restore old VHS or grainy footage?
AI tools may reduce noise and make detail appear clearer, but results vary considerably. Preview moving scenes and faces for invented textures, flicker or distorted text before committing to a full export.
Is 4K export the same as AI 4K upscaling?
No. A tool may export a 4K file without using super-resolution models. True AI upscaling attempts to improve perceived detail while enlarging the footage, though generated detail may not match the original scene.
Does free online AI video upscaling have limits?
Often yes. Free tiers may cap input resolution, length, credits, output quality or downloads. Check the current terms and free-versus-paid feature table before uploading a large or sensitive video.
Final Verdict: Which AI Video Upscaler Should You Choose?
For desktop creation and repeat upscaling tasks, start with UniConverter if you want AI enhancement, batch handling, and additional video tools in one program. Consider Topaz Video for demanding restoration or Video2X if your priority is a no-subscription open-source workflow. For phones, Wink is an accessible starting point; for browser jobs, TensorPix offers credits-based cloud processing, while UniConverter Online is best understood as a lightweight quality-restoration option rather than a full 4K desktop replacement.
Whatever you choose, judge the result by a moving preview of your own source footage—not by a promise of 4K, 8K or “one-click perfection” alone.
