How to use the MOV to WEBM converter
- Choose your MOV video or drop it on the box.
- Check the settings. "Same as original" resolution is fastest. Lower it to 720p for a smaller file.
- Click "Convert to WEBM". A progress meter shows how far along it is.
- Download your WEBM.
Why convert MOV to WEBM?
WebM is ideal for web pages and HTML5 players. MOV to WebM turns iPhone or Mac clips into browser-friendly video.
- MOV: iPhone MOV files often use HEVC, which some Windows PCs and older Android phones cannot play.
- WEBM: royalty-free.
- WEBM: small files with VP9.
Short clips work best: VP8 encoding in a browser is slower than H.264.

Does converting MOV to WEBM lose quality?
MOV (H.264 or HEVC) has to be re-encoded to WEBM (VP9 or VP8 (sometimes AV1)). At "Balanced" quality the difference is very hard to see; choose "High" for footage you will edit again.
How long does it take?
Re-encoding video uses your device's processor. A short clip takes seconds; a 10-minute 1080p video can take several minutes. Choosing 720p makes it 2–3 times faster.
What is a MOV file?
MOV is Apple's QuickTime container. iPhones and Macs save videos as MOV, usually with HEVC (H.265) or H.264 video. It can also hold editing codecs such as ProRes, which is why Final Cut Pro and many cameras use it.
What is a WEBM file?
WebM is an open, royalty-free video format made by Google for the web. It is based on Matroska and uses VP8, VP9 or AV1 video with Opus or Vorbis audio. Browsers play it natively, and many screen recorders and download tools produce WebM files.
