Top 8 H264 to MP4 Converters on Windows/Mac/Online in 2025

Looking to convert H.264 to MP4? If your H.264 videos are struggling to play on your devices, you're not alone. Despite its impressive compression capabilities and high-quality output, H.264 can sometimes run into compatibility issues. Thankfully, converting H.264 to the more universally accepted MP4 format can solve this problem and ensure your videos play smoothly everywhere.

In this guide, we'll explore the best H264 to MP4 converters for making this conversion, so you can easily enjoy your videos without any hiccups.

Part 1. Understanding the H264 Format: How Does it Differ From MP4?

H264, also known as Advanced Video Coding (AVC) or MPEG-4 Part 10, stands as a contemporary compression standard for videos. Employing a block-oriented approach, it excels at delivering high-quality videos while significantly reducing storage requirements and maintaining a low bitrate. Although H264 is practical and cost-effective, it faces compatibility challenges due to its recent introduction.

While H264 and MP4 might seem similar, they differ technically. H264 serves as a coding format for compression, recording, and distribution, whereas MP4 is a video container format capable of housing video, audio, and multimedia data independently. Therefore, H264 requires a video container for the encoded video, while MP4 is a self-sufficient container format. Despite H264 predominantly using AVC for encoding, it can also be encoded in other formats like AVI, MOV, and MKV.

Key Advantages and Drawbacks of H264:

Pros

Efficient compression results in file sizes 3X smaller compared to other codecs.

Low bitrate with higher picture quality than MPEG-2, MPEG-4, H263, and other codecs.

Well-suited for slow-motion videos.

Real-time video and image compression capabilities.

Reduced bandwidth usage owing to smaller compressed files.

Cons

Compatibility issues with various players and devices due to its relatively recent standardization.

High CPU time required for file compression, contributing to computing complexity.

Greater hardware overhead compared to other standards.

Involvement in complicated licensing agreements.
