About
About BlackWhitePDF.
BlackWhitePDF is a small, independent tool for cleaning up documents right in your browser. No accounts, no uploads, no tracking — just a focused utility that does one thing well.
Why we built it
Phone photos of book pages and exported slide decks look messy when you print, archive, or share them, and most fixes meant uploading private files to an unknown server. We wanted a tool that never asks you to do that. So BlackWhitePDF runs entirely on your device and keeps the experience deliberately simple.
Our privacy stance
Sensitive drafts, scanned books, and client files should never need a third-party upload just to be cleaned up. Every conversion happens locally in your browser, your files are never sent to us, and no account is required.
