About ToolPDF

ToolPDF provides simple, reliable tools for everyday PDF and image tasks — merging, splitting, compressing, signing, converting and resizing.

We built it around two principles:

• Your files stay with you. Every tool runs in your browser. Documents are never uploaded to our servers.
• Honest about limits. Each tool explains what it can’t do well, so you aren’t surprised by the result.

We’re starting with a small set of tools and adding more based on what people actually need. If there’s a tool you’d like, let us know.

Open-source software we use

• PDF.js by Mozilla (Apache License 2.0) — displays PDF pages.
• pdf-lib (MIT License) — creates and modifies PDFs.
• JSZip (MIT License) — packages multiple files into a ZIP.
• fontkit (MIT License) — embeds fonts for non-Latin text in edited PDFs.
• Inter and Noto typefaces (SIL Open Font License 1.1).
