About the M4V to WebM Converter
Convert M4V to WebM online for free, with no account and no watermark. M4V is Apple-centric and some players and portals do not recognise it, 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 M4V to WebM Converter
- Click "Choose files" or drag your M4V 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 M4V 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.
