PDF Compress

Shrink a PDF by downsampling the images inside it — a real reduction, not just a re-save. This needs a hosted service — your file is uploaded to be processed, then deleted.

This tool uploads your file. It is sent over HTTPS to our own compression service, processed, and returned — the file is deleted right after processing and never stored. Savings come from the images inside the PDF, so a text-only document will barely shrink.
