About PDF Tools

PDF Tools is a free, browser-based collection of PDF utilities. Merge, compress, and split PDF files without uploading anything to a server.

Every operation runs entirely in your browser using JavaScript. Your documents never leave your device — we have no server that receives them, because they never need to go anywhere.

Why private matters for PDFs

PDFs often contain sensitive content: contracts, medical records, financial documents, legal filings. Most online PDF tools upload your files to a cloud server. We think that's an unnecessary risk when the same work can be done locally in your browser.

Available tools

• Merge PDF — combine multiple PDFs into one
• Compress PDF — reduce file size without quality loss
• Split PDF — extract individual pages
