What is a video compressor?
这是什么
A video compressor reduces the size of a video file by re-encoding it at a lower bitrate while keeping it looking smooth. filecompressor.app uses FFmpeg compiled to WebAssembly, so the entire process runs in your browser — your video never gets uploaded to a server.
This makes it private, free, and ideal for shrinking videos to fit Discord's 10MB limit, email attachments, or website uploads. You can target a specific size or let the compressor pick a balanced setting that keeps quality high.
How to compress a video
使用方法
Compressing a video takes a few steps and runs entirely on your device:
- 1
Drop your MP4, MOV, MKV, AVI, or WebM file into the dropzone above, or click to browse.
- 2
The compressor re-encodes the video with FFmpeg.wasm at a balanced CRF, or targets a specific size like 10MB for Discord. You will see the new size and percentage saved.
- 3
Click Download to save the smaller MP4. The output is H.264 video with AAC audio, compatible with almost every player and platform.
