Free PDF tools that respect your privacy

PDF tools are essential for modern workflows — editing contracts, converting formats, signing agreements, redacting sensitive numbers. Most online PDF tools require uploading your file, which means it passes through their TLS termination, RAM, and possibly a queue before they touch it. PDFCatalyst processes everything in your browser, so the bytes never leave your device. Whether you need to merge PDFs, split a long contract, compress before sharing, or convert between formats, the workflow runs without a single network round-trip — verify in DevTools' Network tab. Free for unlimited use; no signup, no card, no per-document watermark.
