FAQ
Do you upload my files?
No. Everything runs locally in your browser with ffmpeg.wasm; your file never leaves your device.
How much can I compress?
It depends on the preset. 'Small File' can cut the size by 50–80% but may affect quality.
Is there a file size limit?
Up to 500 MB on a computer and 100 MB on a phone: the whole file is processed in your browser's memory.
