How it works, what you get, limits
O que faz
Shrink a finished clip so it can post. You can also trim a time range. Prefer a desktop browser.
Como usar
Pick a video, set width, quality, max MB and in/out, then compress. No video track fails.
O que você recebe
A smaller file. Missing encoders fail with a reason — you will not get a silent “success” with audio only.
Opções e comparação
Width, quality, size cap, start and end time.
Use the editor for cuts and captions; this page is for size.
Limites
No WebCodecs or encoder: hard fail. Prefer desktop Chrome or Edge.
