Drop a video. Watch it shrink.
See the difference
Before vs. After
Drag the handle. Same clip, a fraction of the size — and it never touched a server.
90% smaller — and the quality still holds up.
Why ClipSqueeze
Privacy, speed, and simplicity
Everything most compressors do — minus the upload, the wait, and the privacy trade-off.
Truly private
No upload, no server, no cloud. Your video is decoded and re-encoded entirely inside your browser tab.
Multi-threaded speed
Runs ffmpeg.wasm across all your CPU cores, with a stream-copy fast path that skips re-encoding when it can.
Hit any size
Email, Discord, WhatsApp, Telegram, Slack — or a custom MB target. It verifies the result and re-encodes if it overshoots.
Trim & downscale
Cut the start or end and drop to 1080p/720p/480p/360p before encoding to save even more space.
Smart targeting
Bitrate is calculated from your target size and clip length, then auto-corrected to actually land under the limit.
Free forever
No watermark, no signup, no usage cap. Compute runs on your machine, so there's nothing to charge for.
Works with your formats
Drop common video files in — get a universally compatible MP4 or a smaller WebM out.
Privacy-first
The private video compressor
Most online compressors upload your footage to a server you don't control. ClipSqueeze doesn't — everything runs locally. Don't take our word for it:
Open DevTools → Network → compress a clip.
You'll see zero requests carrying your video.
Files never leave your device
Compression happens in your tab. The bytes stay on your disk.
No uploads, ever
There's no server to upload to. We couldn't see your files if we wanted to.
No tracking
No analytics on your content, no fingerprinting, no ad pixels.
No account required
Nothing to sign up for. No email, no password, no cookies to accept.
