Compress a gameplay clip
Free, in your browser, nothing uploaded. Drop the file, press the button.
Capture software records at very high bitrates on purpose — great for editing, terrible for sharing. A 30-second ShadowPlay clip can top 200 MB. Drop it here (MKV from OBS works too) and ShrinkClip re-encodes it to fit Discord's 10 MB free limit without touching a server.

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
Can I compress OBS's MKV files?
Yes. MKV is read natively in your browser, and the output is a standard MP4 that Discord embeds and plays inline.
Why does fast motion look blocky after compression?
Fast, high-detail motion is the hardest thing to encode — a 10 MB budget for a long clip has to smear something. Trim to the moment that matters; shorter clips keep dramatically more quality.
