Compress a video without losing quality
Free, in your browser, nothing uploaded. Drop the file, press the button.
Honest answer: visually lossless is achievable, mathematically lossless is not — anyone promising otherwise is selling something. Most videos carry far more bitrate than the eye uses, so ShrinkClip cuts the surplus first: sane H.264 encoding at a computed bitrate, downscaling only when the numbers demand it.

No upload queue
Compression runs on your own CPU. A 500 MB recording never crawls up your connection to someone's server — there's nothing to upload, wait on, or trust.
No command line to learn
The same H.264 encoding professionals tune by hand — with the bitrate math and resolution worked out for you. Pick a size, press the button.
Private by default
Your video is processed in browser memory and discarded when you close the tab. We never see a frame of it — only anonymous size and preset stats.
Questions people actually ask
Is lossless video compression possible?
Truly lossless codecs exist but barely shrink files — and sometimes grow them. Meaningful size cuts are always lossy; the craft is spending the remaining bits where perception actually looks.
Which setting keeps the most quality?
The biggest target size you can get away with. If the file just needs to be smaller — not under a hard limit — “Smallest possible” keeps short clips crisp; for hard limits, pick the platform preset and keep the clip short.
1080p or 720p — which looks better compressed?
At low bitrates, sharp 720p beats smeary 1080p. ShrinkClip only steps down when the per-pixel bitrate would fall below watchable — the same call a video engineer would make by hand.
