Features
Why use our MOV to WebM Converter?
Modern Codecs
Encodes with VP9 video and Opus audio, the same codecs YouTube and modern browsers use natively for WebM.
Universal Playback
MOV files are often unsupported on phones, social platforms, and modern editors. Converting to WEBM fixes that.
Batch Convert Multiple Files
Drop in as many MOV files as you need and convert them one after another, downloading each finished WEBM individually.
Progress You Can See
Every file shows a live progress bar while it converts, plus before and after sizes when it is done.
100% Private
Your files never leave your device. Every conversion runs locally in your browser, so nothing is uploaded, stored, or seen by anyone.
No Sign-up Required
Open the page and start converting. No account, no email, no install, no watermark.
FAQ
Frequently asked questions
Is my video uploaded to a server?
No. The conversion runs entirely in your browser using a WebAssembly build of FFmpeg. Your video never leaves your device.
Why does the first conversion take a moment to start?
The FFmpeg engine (about 31 MB) is downloaded and set up the first time you use any video or audio converter on the site. After that it is cached and conversions start right away.
Will converting reduce my video's quality?
MOV and WEBM use different codecs, so the video is always re-encoded. The encoder runs at a high quality setting that is visually very close to the original.
How long does conversion take?
Re-encoding runs without hardware acceleration in the browser, so expect roughly real time or slower for long, high resolution clips. Keep the tab open and active while it works.
Why convert MOV to WEBM?
WEBM is supported by essentially every device, video editor, and platform, while MOV support is more limited. Converting fixes playback and upload problems.
Is there a file size limit?
There is no hard limit, but very large videos use a lot of memory and can be slow or unstable in some browsers. Files over about 600 MB show a warning.
Is this converter free?
Yes. It is free to use with no sign-up, no account, and no watermark on your files.
