PRIVATE BROWSER PROCESSING
Convert MOV to MP4 before the file becomes someone else's problem
MOV is common from Apple devices, cameras and editing workflows. MP4 is usually less awkward when the next step is email, a website, a form, Windows, or a social upload.
MOV to MP4
MOV is normal in production; MP4 is easier at the hand-off
MOV is a container, not one codec. This tool re-encodes the main video as H.264 with AAC audio so the output behaves predictably as MP4.
Privacy and limitations
Processing uses FFmpeg WebAssembly locally. The video is not uploaded by this tool. Closing or refreshing the page clears the working file. Speed depends on the browser, device memory, source codec, duration, and resolution, and tools that re-encode are not lossless.
Common questions
Can I just rename the file extension?
Usually not. Renaming does not change the container or codecs inside; this page performs a real conversion.
Is my video uploaded to DJAI?
No. The source file is read and processed in your browser on your device.
Why can the first run take longer?
The browser downloads an FFmpeg WebAssembly core of roughly 31 MB the first time processing is needed; caching can help later runs.
