MOV to WEBM Converter

Convert MOV files to WEBM. Free, without uploading.

This tool converts MOV files to WEBM. MOV is Apple’s QuickTime format. iPhone videos and editing software use it a lot; it can cause trouble on Windows and some websites.

WEBM is an open video format built for the web (VP8/VP9 video, Opus audio). Browsers play it natively. The video is re-encoded with VP8 video and Opus audio. You choose the quality and resolution, and can trim it with a start and end time.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the MOV video, drag it in, or paste its link.
2. Choose the quality and resolution; optionally enter trim times.
3. Press "Convert" and download the WEBM file.

Frequently asked questions

How long does MOV to WEBM take?

It runs on your device’s processor. On a computer a one-minute 1080p video usually takes a minute or two; lowering the resolution speeds it up.

Is there a file size limit?

No fixed limit; your device’s memory decides. Computers usually handle files up to 1–2 GB.

Is my file uploaded?

No. Your MOV file is converted to WEBM inside your browser.
