Compress WebM Online
WebM is already the web's own efficient format, so this page works with a smaller budget than the legacy containers get: a well-encoded VP8/VP9 file has less slack, and the honest result is sometimes "barely smaller". Where the weight still has to come down — an embedded loop, a capped upload, a page that crawls — a tighter bit-rate reaches further than most formats will allow.

Perguntas frequentes sobre compressão de Video
Is WebM smaller than MP4?
For comparable clips, usually — its codec family beats older H.264 encodes on weight. Which one wins also depends on what has to play it.
Can WebM go anywhere a video goes?
Web embeds are its home; some editors and mail clients still prefer MP4, which makes converting the more useful step there.

The result is downloaded as a separate file. Keep your original until you have checked the Compressed WebM.

Freelancers bookmark the compress WebM because it removes the install-and-export cycle from traditional desktop compressors.
When a client portal rejects an upload, rerun the compress WebM with tighter settings instead of rebuilding the project from scratch.
