Frequently asked questions
How much smaller will my video get?
It depends on the source and the level you pick. The Balanced preset typically cuts size substantially with little visible loss; Maximum goes smallest at the cost of sharpness. The result card shows the exact size saving.
How does compression work here?
It re-encodes to H.264 MP4 using constant-rate-factor (CRF) encoding — the same technique professional tools use — entirely in your browser.
Is my video uploaded?
No. Compression runs on your device with FFmpeg. Nothing is uploaded.
