ClipShrink
Free, private in-browser video compression using WebAssembly
ClipShrink is a free, client-side video compressor that shrinks MP4, MOV, and WebM videos directly in your browser using local WebAssembly. Unlike traditional cloud compressors, files never touch remote servers—ensuring 100% privacy, zero upload queues, and no watermarks. Includes automated presets to fit exact platform upload limits: Discord (8MB), WhatsApp (16MB), Gmail (25MB), Outlook (20MB), and Slack (10MB).
Hey Product Hunt!
I built ClipShrink because I was tired of legacy online video compressors that make you upload personal clips to their cloud servers, wait in long artificial queues, or demand paid subscriptions just to send an 8MB clip on Discord or an email attachment.
ClipShrink takes a different approach: 0 bytes ever leave your device.
By compiling FFmpeg into client-side WebAssembly (WASM), your computer or phone's own processor re-encodes the video locally in browser memory.
Key features:
- 100% Client-Side Privacy: Video files never touch external servers.
- Zero Upload Latency: Processing starts the millisecond you drop the file.
- Target Platform Presets: Automatically hits exact limits for Discord (8MB), WhatsApp (16MB), Gmail (25MB), Outlook (20MB), and Slack (10MB).
- Clean Experience: No watermarks, no account signup required, completely free.
Tech Stack: Next.js (App Router), React 19, Tailwind CSS, and self-hosted FFmpeg WASM binaries. The core WebAssembly wrapper is open source on GitHub!
I’d love to hear your thoughts, feedback on encoding speed across different hardware, or feature requests. Thanks for checking it out!
