free PDF compressor FAQ

Is this tool free?

The page is designed as a free online tool flow with batch selection, processing and download.

Are PDFs uploaded to a server?

No. PDF pages are resampled and rebuilt locally in the browser. Neither the original nor the result is uploaded.

Why do some PDFs not shrink much?

The tool compares a structure-optimized version with an image-resampled version and keeps the smaller result. Files that are already highly compressed may still change very little.
