PDFMaster AI is a free, browser-based suite of PDF tools built on open-source libraries like pdf-lib and pdf.js. We believe document tools should be fast, private and free for everyone.
Every tool on this site runs entirely in your browser. Your files are never uploaded to a server, never stored, never seen by us. The site is hosted on the edge and supported by non-intrusive advertising.
No accounts. No paywalls. No watermarks. If a feature ever requires a paid tier, the existing tools will stay free.
