Is compressing WebP free?

Yes. Compression is free with no signup on webp.now, and guests can compress up to 10 files a day.

How much smaller will my WebP file get?

It depends on the source. A WebP exported at quality 90+ typically halves at quality 80 with no visible difference. A file already compressed hard has much less to give — the tool will tell you the saving before you download.

Does compressing lose quality?

Lossy compression always discards some data. Above quality 80 the difference is invisible at normal viewing sizes; below 60 you will start to see softness and blocking in flat areas like skies.

What is lossless mode for?

Lossless re-encodes the image with no quality loss at all, which still saves space on screenshots, logos and line art. On photographs it saves very little — use lossy for those.

Can I compress to a specific file size?

Yes. Set a target size in KB and the encoder binary-searches for the highest quality that fits under it. Useful when an upload form enforces a hard cap.

Are my files kept private?

Files are processed on secure servers over TLS and deleted automatically within 24 hours. They are never used as training data or reviewed for analytics.
