About the MOV to WebM Converter
Convert MOV to WebM online for free, with no account and no watermark. Windows PCs, Android phones and upload portals often struggle with MOV (frequently HEVC) videos, so switching to WebM is the quickest way to get a royalty-free WebM for the web for website background videos, HTML5 players and royalty-free publishing.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your videos are never uploaded, stored or seen by anyone else, which makes it safe for family videos, client footage and private recordings.
What to expect: the resolution is kept unless you choose a smaller size, and the audio track is converted too; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the MOV to WebM Converter
- Click "Choose files" or drag your MOV videos onto the box. You can add several at once.
- Choose the output resolution and quality preset.
- Press "Convert to WebM". The conversion runs on your device and shows its progress.
- Download each WebM file, or use "Download all (ZIP)" when you converted several.
- Open the result in Chrome or Firefox to check it; your original MOV is never changed.
Tips & benchmarks
- WebM output uses VP8 video with Vorbis audio for the widest browser support; encoding is slower than MP4.
- Very large videos (over about 1 GB) may exceed the memory of a phone browser; trim them first with our Trim Video tool.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the WebM to a website or government portal.

What is the difference between MOV and WebM?
MOV (Apple QuickTime Movie) is a QuickTime video container best suited to editing on Macs in Final Cut Pro and iMovie. WebM (WebM video) is a open web video container best suited to website background videos, HTML5 players and royalty-free publishing.

There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
