Why ClipBunny
100% private by design
Every byte stays on your device. ClipBunny processes video inside your browser using WebAssembly — there is no server to upload to, nothing for us to see.
Tuned for every platform
Pre-configured presets for Twitter, Discord, WhatsApp, LinkedIn, Slack, TikTok, Instagram, and more. Pick one and the bitrate, resolution, and container are set automatically.
No accounts, no watermarks
Drop a file, get a compressed file. No sign-up wall, no branded overlays, no daily countdowns hidden behind a paywall.

Frequently asked questions
Does ClipBunny upload my video?
No. All compression happens inside your browser using WebAssembly and WebCodecs. The file never leaves your device, which means even we cannot see it.
Is it really free?
Yes, free and ad-free. There's a soft cap of three compressions per day to keep the tool sustainable — clear your browser storage if you need more in a pinch. No account, no signup, no watermarks.
What file formats does it support?
Input: MP4, MOV, WebM, AVI, MKV, MPEG, M4V and more. Output is always H.264 MP4 for the broadest compatibility across platforms.
Why is it slower than online tools that upload my file?
Server-based compressors run on machines with way more CPU than your laptop. ClipBunny trades a bit of speed for total privacy — your video is never on someone else's computer.
