Last updated
Quick answer: To convert WEBM to MOV, add the WEBM file to the iHateFiles WEBM to MOV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Re-encodes the picture and sound into a MOV container.
Should you convert WEBM to MOV?
Do this when something specifically needs MOV. The picture is re-encoded, so it costs a little quality; if all you need is a file that plays everywhere, MP4 is usually the better target.
The picture is re-encoded
A WEBM usually holds VP8, VP9 or AV1 video with Vorbis or Opus sound. This writes H.264 video with AAC sound into the MOV. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from WEBM artefacts rather than the original.
Extra tracks may not survive
A WEBM can carry subtitle tracks. MOV is more limited, so this conversion keeps the main video and the first audio track. If you need the subtitles, save them first with Extract Subtitles.
Where the MOV will play
MOV plays on every Apple device, Windows 10 and later, and most editors.

What usually goes wrong
About the WEBM. A browser screen recording is usually a WEBM with a broken duration, so players show it as zero seconds or refuse to seek. Converting it to MP4 rewrites the header and fixes the seeking.
About the MOV. A MOV recorded on an iPhone is usually H.264 or HEVC and plays anywhere. A MOV exported from an editor may be ProRes, ten times larger, and rejected by the same places.
How to convert WEBM to MOV
- Add your WEBM file. It is read from your disk and stays there.

Questions
How do I convert WEBM to MOV?
Open this page, add your WEBM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WEBM to MOV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to MOV lose quality?
MOV is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several WEBM files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
