Donaldson R F Compress PDF
Shrink your PDF's file size for real — processed briefly on our server, then deleted immediately.
How this works
Unlike the purely browser-based tools on this site, this one briefly uploads your file to our server to run real PDF compression (re-encoding embedded images and optimizing internal structure) — the same technique most "Compress PDF" tools online use. Your file is deleted from the server immediately after processing, and never stored.
