Sut Mae'n Gweithio

Video compression is computationally heavy — most websites farm it out to expensive cloud servers. We use FFmpeg compiled to WebAssembly (ffmpeg.wasm), which runs the real FFmpeg encoder directly inside your browser.

1
FFmpeg.wasm downloads on first use
FFmpeg compiled to WebAssembly is ~30 MB. It downloads once and is cached by your browser. Subsequent compressions skip this step.
2
You pick a video and quality preset
The file is loaded into FFmpeg's virtual filesystem (a JavaScript object representing files in memory). FFmpeg sees the file as if it were on disk, but it's actually just in your browser's RAM.
3
FFmpeg encodes your chosen quality/resolution
FFmpeg runs the same x264/VP9 encoders used in desktop FFmpeg — the same code that powers handbrake, OBS, and most video tools. All encoding happens locally on your CPU.
4
The compressed video is offered for download
The output is written to FFmpeg's virtual filesystem, then handed back to your browser as a downloadable blob.

Compressing a video on someone's server is expensive — that's why most "free" video compressors have file size limits, queues, or aggressive watermarks. Here, your CPU does the work, so there are no file size limits, no queues, and no server seeing your footage. Safe for personal, business, or sensitive content.
