FAQ
How can I compress a video without uploading it?
ClipForge compresses with ffmpeg running as WebAssembly inside your browser, so the file is processed on your own device — never uploaded to a server.
How much smaller will my video get?
It depends on the source and your settings. Lowering the resolution (e.g. to 720p) and raising the CRF value reduces size the most. The result panel shows the new file size.
Will quality drop?
Compression always trades some quality for size. CRF 23–28 keeps things looking good while cutting size substantially.
Is it free and watermark-free?
Completely free, no signup, no watermark.
