Turn your WebM file into a MOV that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MOV is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the MOV, or keep editing the file in REQO.
WebM is the open, royalty-free container built for the web. It is what most browser-based screen recorders produce, and VP9 packs the same picture into noticeably less data than H.264.
The practical problem: Most editing software, phones and TVs will not open a WebM file. Social platforms and messaging apps frequently reject the extension outright. Safari and older Apple devices handle WebM inconsistently.
MOV solves that. Keeps the file native to macOS, iOS and Final Cut Pro. Preferred by some Apple-first editing and motion tools.
| WebM | MOV | |
|---|---|---|
| Container | WebM (Matroska-based) | Apple QuickTime |
| Typical codecs | VP8 / VP9 / AV1 video, Opus audio | H.264, HEVC or ProRes |
| Best for | Web embeds and browser recordings | Editing on a Mac, footage straight off an iPhone |
| Plays on | Chrome, Firefox and Edge; hit and miss elsewhere | macOS and iOS natively, patchy elsewhere |
| File size | Very small at the same quality | Large, especially ProRes |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MOV itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the WebM on normal viewing. Converting the same file back and forth repeatedly will eventually show, so keep your original.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
