The Paji PDF App is a free, private workspace for all your PDF documents. Keep a library of files, open any one to edit — add and burn in custom text, stamp images and signatures, compress and shrink large PDFs, reorder, rotate and delete pages — and send a document to a third party to sign with a shareable link. Everything runs client-side, so your files never leave your device. No signup, no watermark. Prefer a single-file quick edit? Use the PDF editor. Need the individual utilities? Try split, merge, compress and OCR.
