Pixelmin is a free, browser-based video compression tool that processes everything locally on your device. Your videos are never uploaded to any server.
Pixelmin reduces video file sizes using your browser's built-in hardware acceleration, powered by the WebCodecs API and Mediabunny. You pick a target resolution, drop in your videos, and receive compressed files you can download immediately.
Multiple files can be queued at once. The compression engine processes them one at a time to avoid overloading your device, with real-time progress shown for each.
Your files never leave your browser. There are no uploads, no cloud processing, and no analytics tied to your video content. The entire compression pipeline runs inside a Web Worker on your device.
We don't collect, store, or transmit any data about the videos you compress — not their names, sizes, durations, or content.
Pixelmin works best on Chrome, Edge, and other Chromium-based browsers on both desktop and Android, which have full WebCodecs support. On Safari and Firefox, a fallback compression path is used which may be slower.
If compression fails with one codec, Pixelmin automatically retries with an alternative — so you shouldn't need to change settings manually.
Pixelmin is free to use with no account required. There are no file size limits imposed by the application itself — your only limit is the memory available on your device.
