About PapyrasPress

PapyrasPress is a small set of free tools for everyday document chores: making a PDF small enough for an upload form, merging paperwork into one file, pulling pages out of a long document, turning phone photos into a PDF, and shrinking images for email or the web.

How it works

The tools are built on open-source libraries, including Mozilla’s PDF.js and pdf-lib, and run as code inside your browser. When you pick a file, it is read and processed on your device. Nothing is sent to a server, so there is no upload wait, no file-size cap imposed by us, and nothing for anyone to leak.

Our compression approach

We test the PDF compressor against a set of real-world files (scans, brochures, forms, research papers, and PDFs with unusual image formats) and measure both file size and visual difference from the original. The rules that came out of that testing: keep text as text, store scans as clean black-and-white, never return a bigger file, never flatten a fillable form, and be honest when a size target can’t be reached.
