Drop MOV (QuickTime) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Save the WebM, or download everything as one ZIP if you converted several files.
The MOV to WebM converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MOV does not play reliably on Windows, Android, smart TVs or in many upload forms. WebM is royalty-free and well suited to embedding in web pages. MOV is at home in recording and editing on Apple devices; WebM is the usual choice for royalty-free video on websites.
The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. A video over 500 MB cannot be kept at full quality in browser memory; choosing a lower resolution or quality under Options lets it fit.
MOV is Apple's QuickTime container and what iPhones and Macs record. MP4 was based on it, so the two are close relatives and often hold exactly the same video and audio streams inside.
Opens in Apple devices and video editors; Windows and Android are hit and miss

No. The MOV to WebM conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
It depends on what is inside the MOV. When its video and audio are already in a form WebM can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MOV file, press Convert and save the WebM. There is nothing to install.
Yes. Files up to 2 GB are accepted, and a video over 500 MB needs a lower resolution or quality chosen under Options so the result fits in memory. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
