PDF tools online: everything you need to know
PDF (Portable Document Format) is the world's most used document format, created by Adobe in 1993. Its strength is looking identical on any device, but that makes editing complex without specialized software.
Convertir.ai's PDF tools let you manipulate PDFs without installing Adobe Acrobat. Merge documents, split long PDFs, rotate scanned pages, add numbering, password-protect, and more — all from your browser.
All operations run locally using pdf-lib.js, an open-source JavaScript library. Your documents never leave your device — especially important for confidential documents.
