Why doesn't my website or app accept an iPhone .mov file directly?

Some platforms specifically expect the .mp4 container and don't recognize .mov, even when the underlying video codec would otherwise be compatible — this tool re-wraps and re-encodes to resolve that mismatch.

Does this also fix HEVC compatibility issues?

Yes — MOV files from Apple devices often use HEVC (H.265), which many platforms and older software don't support even though Apple devices play it natively. Re-encoding to H.264 resolves that separately from the container format itself.

Is my video uploaded anywhere?

No — conversion runs entirely inside your browser using a real FFmpeg build compiled to WebAssembly.

Will video quality change during conversion?

Since this is a genuine re-encode (especially when converting from HEVC), some quality change is inherent, though generally not noticeable at normal viewing sizes with standard settings.

How long does conversion take?

Proportional to the video's length and resolution — a progress bar tracks the actual encoding progress as it runs.

About Apple MOV to MP4

iPhones and QuickTime save video in the .mov container by default, which internally usually already uses H.264 or HEVC video — but the .mov container itself trips up some websites, upload forms, and non-Apple software that specifically expect .mp4, even though the actual video data inside is often nearly identical to what a proper MP4 would contain. This tool re-wraps and re-encodes a MOV file as a standard MP4.

A real FFmpeg build compiled to WebAssembly handles this entirely inside your browser, decoding the source video (whatever codec it actually uses — H.264 and HEVC are both common in MOV files from Apple devices) and re-encoding to H.264/AAC in an MP4 container, the combination most broadly supported across platforms that don't recognize .mov specifically.

This is a genuine re-encode rather than a fast container-only swap, since MOV files can contain HEVC video (H.265), which many web platforms and older software still don't support even though Apple devices handle it natively — converting to H.264 resolves that compatibility gap on top of just fixing the container format.

The result is a video file that opens correctly on virtually any platform or device that accepts video uploads at all, resolving both the container mismatch and any underlying codec incompatibility in one step.

How it works

Upload your MOV file. The file loads into the browser-based FFmpeg engine.
Conversion runs locally. FFmpeg decodes and re-encodes to H.264/AAC MP4.
Download the MP4. A widely compatible video file, ready to share.
