Getting started
- Open compress.lol in a current browser and drag in your video.
- Choose a target size or one of the listed presets, then trim the clip, mute it or pick audio-only if needed.
- Start compression, download the result and check that it plays and fits the limit you needed.
Decision points
- Check your browser before choosing it: the README lists Chrome and Edge 94+, Safari 16.4+ and Firefox 130+ for the fast path, and WebAssembly with SharedArrayBuffer for the fallback.
- If you need batch processing or a watch folder, the sources reviewed do not mention them; compare a desktop compressor.
Limits
- A very small target size lowers quality; if the first result exceeds the target the tool may re-encode with adjusted settings, so check the final video.
- The fallback component, FFmpeg.wasm, is loaded on demand from content delivery networks, so a first run may need an internet connection.
- The sources reviewed do not state account, watermark or pricing terms; verify them on the output you download.
