Why convert WebM to MOV?
Both WebM and MOV use lossy compression, so the conversion mainly changes compatibility, not quality. The main reason to convert WebM to MOV is compatibility: MOV plays back smoothly in browsers and on mobile without a codec pack, while WebM doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, MOV is usually the safer target.
Format comparison
| WebM | MOV | |
|---|---|---|
| Extension | .webm | .mov |
| MIME type | video/webm | video/quicktime |
| Compression | lossy compression | lossy compression |
| Category | video | video |
Common reasons to convert WebM to MOV
- Meeting an upload size limit for a platform or an email attachment
- Playing back on a device or app that doesn't support WebM
- Standardizing on one format so every file behaves the same way in your workflow
What actually happens to your file
This is a real transcode, not a container swap: WebM's VP9 video and Opus audio are decoded and re-encoded to H.264 (CRF 23) and AAC (160 kbps), so the result plays natively in QuickTime, Final Cut, and other Apple-ecosystem tools that don't support VP9. Expect a genuinely new encode pass, not a bit-for-bit repackaging.
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →

Will I lose quality converting WebM to MOV?
MOV is apple quicktime's video container, the default on iphone. We use the highest-quality encoder settings by default so visual or data loss is minimized.

Will my converted file have a watermark?
On the Free plan, MOV output includes a small "Converted with Convyx" mark. Pro ($9/mo) removes it, along with the 25 MB file size cap.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click. Monthly quotas count attempts (including failures) because processing starts as soon as the job is created.
