Free Video Compressor
Shrink a video's file size, with an optional trim to compress just part of it — free, no sign-up, nothing leaves your browser.
Shrink a video's file size, with an optional trim to compress just part of it — free, no sign-up, nothing leaves your browser.
Standard works instantly on any device, but takes roughly as long as the video's own length to process. Fast mode processes the file directly rather than through playback, so it's usually quicker for longer videos.
Resolution is the pixel dimensions of the video — how much detail fits in each frame. Bitrate is how much data is used to encode each second of playback, regardless of resolution. Lowering resolution shrinks the file by having fewer pixels to encode in the first place; lowering bitrate shrinks it by allowing more compression artifacts and less fine detail at the same pixel dimensions. A video can be small-but-sharp (low resolution, decent bitrate) or full-size-but-soft (full resolution, low bitrate) — they're two separate dials, not the same setting under different names, and the best combination depends on where the video is headed: a small preview thumbnail can tolerate a lot of compression, while something meant to be watched full-screen benefits more from keeping resolution higher and trimming bitrate instead.
Yes, completely free with no sign-up and no watermark by default.
It re-renders your video at a lower resolution and/or bitrate than the original — similar to how any video compressor works, just running in your browser instead of on a server.
With Standard, the video has to be played through in real time to be re-recorded at the new settings, so it takes roughly as long as the video itself. Fast mode isn't tied to playback speed — it processes the file directly, which is usually quicker for longer videos.
Standard works instantly on any device, but can't process faster than the video plays. Fast mode loads a real compression engine (ffmpeg, compiled to run in your browser) that isn't bound to playback speed, so it's often faster overall for longer videos.
No. Everything happens locally in your browser — your video is never sent to a server.
Yes — turn on "Only compress part of the video" and drag the trim handles to select the section you want, before choosing your resolution and quality.
We've noticed an ad blocker is active. Cwtch.es relies on ads to stay free, so videos compressed while a blocker is active will include a small Cwtch.es watermark in the corner. Disable your ad blocker for this site (or add it to your allow-list) and recheck to compress without it.
