Working…
✅ Done — your WebM video
How it works
- Step 1 — Drop in your MOV file. A video engine loads once in the background (~9 MB, then cached).
- Step 2 — Pick a quality preset or set CRF yourself; choose whether to keep the audio track.
- Step 3 — The video is re-encoded to VP9 + Opus WebM locally and downloads to your device — ready to embed on any website.
Everyday uses
- Web developers — shrink hero and background videos for faster page loads.
- Bloggers — embed videos that start instantly in every browser.
- iPhone users — turn heavy MOV clips into shareable, lightweight WebM.
- Creators — publish web-optimized video without paying for a converter.
Rule of thumb: CRF 30 gives transparent VP9 quality for most MOV sources — go to 22 only for archival quality.
