Compress a PDF without sending it anywhere

Embedded photos are recompressed right in your browser — text and layout stay untouched.

Your PDF never leaves the device when processed in the browser — the server doesn't get it.
Only embedded photos are recompressed — text and layout are left untouched.

How it works

Add PDFs
One file or several at once — drop them in the upload area or pick them with the button.
Embedded photos get recompressed
The browser parses the PDF structure, finds embedded JPEG images and recompresses them — text, fonts, and vector graphics stay as they are.
