Turn your MOV file into a WebM 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.
WebM 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 WebM, or keep editing the file in REQO.
MOV is Apple’s QuickTime container. It is what an iPhone and Final Cut hand you, and it can hold anything from ordinary H.264 to enormous ProRes masters, which is exactly why it travels badly outside the Apple ecosystem.
The practical problem: Windows and Android often refuse to play MOV files, or play the picture with no sound. ProRes MOV files from a camera or Final Cut can be ten times larger than the same footage as MP4. Some upload forms reject the extension even when the video inside is ordinary H.264.
WebM solves that. Streams natively in Chrome, Firefox and Edge with no plugin. VP9 delivers smaller files than H.264 at the same visual quality, which cuts bandwidth on a busy page.
| MOV | WebM | |
|---|---|---|
| Container | Apple QuickTime | WebM (Matroska-based) |
| Typical codecs | H.264, HEVC or ProRes | VP8 / VP9 / AV1 video, Opus audio |
| Best for | Editing on a Mac, footage straight off an iPhone | Web embeds and browser recordings |
| Plays on | macOS and iOS natively, patchy elsewhere | Chrome, Firefox and Edge; hit and miss elsewhere |
| File size | Large, especially ProRes | Very small at the same quality |
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 WebM 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 MOV 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.
