Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Easily convert your MP4 video files into MOV format with ConvertX. This tool is ideal for users who need to ensure full compatibility with macOS and iOS professional video software.
MP4 is a highly compressed, cross-platform standard, while MOV (QuickTime File Format) acts as a container developed by Apple. During conversion, we re-wrap the video streams into the MOV container, which is native to Final Cut Pro and macOS environments, ensuring better integration with Apple's ecosystem.
Since we use a lossless container remuxing process, your video quality remains 100% identical to the original MP4 file.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
