UniConverter 18 brings faster, higher-fidelity 4K/8K conversion, better control over
compression size and quality, and upgraded AI video and image enhancement
—with smarter batch automation to
reduce repetitive work.
Give AI Agent your media and a prompt describing the use, platform, or delivery limit. It interprets the intent, plans conversion steps, and adapts the settings when different files need different treatment.
New audio pass-through keeps high-quality streams in their original codec while subtitles, chapters, metadata, and multi-track structure stay with the file.
The upgraded model predicts the final file size more accurately and improves visual quality at the same compression ratio, reducing repeat exports.
AI Auto Fix chooses a tailored image repair and Photo Straightener corrects photographed scans. Face Enhancement-Ultra brings clearer, more natural portrait detail without requiring a specific GPU.
Watch Folder applies saved rules as files arrive. Custom CPU allocation lets long queues continue without taking over foreground work.
AI Brush recognizes complete boundaries from a rough mark. V18 also adds one-click fixed-subtitle removal and upgrades static-watermark and moving-object erasure.
Select detected faces or draw around any moving plate, logo, or screen. Apply blur or mosaic to multiple targets, or invert the mask to soften the background.

Usually I don't write review for any product I use, but this will be my first review for this software, powerful, smart, easy to use and gets more advanced by time.
Wondershare UniConverter makes converting 4K and 8K video files a breeze, ensuring high-speed performance. Additionally, it simplifies video compression, all while offering an intuitive and user-friendly interface for seamless navigation.
Getting the files converted was the first step and Uniconverter came through for me. I was also impressed that Uniconverter did it fast but also preserved the metadata, even cover artwork, on files I had updated prior to converting.
We use Uniconverter for more than 10 years as Video Converter in our daily work. Also the former version some years ago, which was called Video Converter Ultimate was in constant use to convert videos, cut videos and edit them. On the other hand, we work as reseller of Wondershare Uniconverter and it is one of the best products of Wondershare.
Not cheap, to be honest. But I'm very impressed with the quality of the product. The video compression is top-notch, allowing me to quickly convert videos to any format I need. The user interface is also intuitive, making it easy for me to quickly figure out how to use the different features.
Wondershare software is awesome and their support is equally as awesome. They worked with me to get the issues resolved. Highly recommend Wondershare UniConverter.
The price is fair. The user interace is actually pleasant (I like the dark aesthetic). It's easy to queue up a large batch of conversions and leave them running in the background. Everything is generally pretty fast and snappy.
