About PDF Modern
A free, modern, privacy-first PDF toolkit that runs entirely in your web browser.
What is PDF Modern?
PDF Modern is a collection of fast, modern online PDF utilities. You can merge PDFs, split PDFs, compress PDFs, convert PDF to JPG, turn JPG/PNG into PDF, rotate pages, reorder or delete pages, add a watermark, add page numbers, and protect or unlock a PDF with a password.
Why we built it
Most online PDF converters demand that you upload your private documents to an unknown server. We didn’t like that — so we built a toolkit that does the work inside your browser using modern WebAssembly. Your files never leave your device. Nothing is uploaded, nothing is stored, and nothing is logged.
How is it free?
Because there is no server to pay for. PDF Modern is a static website served from a global content delivery network — your browser does all the heavy lifting. That means no usage limits, no daily caps, no signup, no credit card and no ads inside the tools.
Privacy & security
- All processing happens locally in your browser tab.
- No PDF or image is ever uploaded to a server.
- No accounts, no tracking cookies, no third-party analytics inside tools.
- PDF password protection uses industry-standard AES encryption.
