Why PDF Toolkit?

Your files stay private

Client-side tools process your PDFs entirely in your browser. Your files are never uploaded to any server. No data collection, no storage, no risk.

Fast, no waiting

No upload or download queue. Client-side tools start processing the instant you drop a file. Large documents process in seconds, not minutes.

100% free, no sign-up

Every tool is free to use with no account required. No trial periods, no watermarks on output, no per-file limits. Just drop your file and go.

Works on any device

Desktop, tablet, or phone — PDF Toolkit works in any modern browser. No software to install, no plugins, no Java applets from 2004.

31 tools and growing

From merging and splitting to OCR and AI summaries, we cover every PDF workflow. New tools are added regularly based on what users need most.

Reliable output

Built on pdf-lib and pdfjs-dist — battle-tested open-source libraries. Your output files are standards-compliant and work everywhere.
