Scans and image-heavy decks benefit most.
Rebuilt on your device
Each page is re-rendered and its imagery re-encoded as efficient JPEG — text stays sharp at reading size.

Check the before/after size on each file. The original is untouched.
The PDFs that blow past email limits are almost never text — they're scans and slide decks where every page is secretly a large image. This tool rebuilds your PDF with each page's imagery re-encoded at a sensible quality, which is where the real savings live: 50–90% for scans and photo-heavy decks.
PDFs are also the documents you least want on someone else's server — contracts, medical results, tax scans. This compressor never uploads anything; the rebuild happens entirely in your browser.
Free, private, no upload. Ever.
This tool runs entirely on your device. It's built by the team behind RenameTo for Mac — where the same job is just a rename in Finder.
