Convert Apple QuickTime MOV files to WebM format for web publishing — no software to install, no registration, and no watermarks. Uploaded files are automatically deleted after one hour.

Why convert MOV to WebM?

MOV files from iPhones, iPads, and Mac screen recordings use Apple's QuickTime container, which may not play in all browsers or on non-Apple devices. WebM (VP9/Opus) is an open, royalty-free format designed for web streaming. Converting MOV to WebM reduces file size and ensures smooth HTML5 video playback across Chrome, Firefox, Edge, and Opera.

Quality settings

Adjust the CRF (Constant Rate Factor) to balance quality and file size. The default value of 30 suits most web content. Use lower values (20–25) for higher quality or higher values (35–45) for smaller files optimized for faster loading.

Frequently asked questions

Will the audio be converted too?

Yes. The audio track is re-encoded from AAC (common in MOV) to Opus, which is the standard audio codec for WebM. Opus provides excellent quality at low bitrates.

Can I convert iPhone videos?

Yes. MOV files recorded on iPhone (including HEVC/H.265) are supported. The tool will re-encode the video to VP9 for WebM compatibility.
