A private alternative to online PDF converters
Most online PDF tools upload your documents to their servers. PDF Worker does the work inside your browser instead, so contracts, IDs and medical records stay on your computer or phone. It merges, splits, compresses and converts PDFs, edits existing text, fills forms, adds signatures, recognizes text in scans, redacts sensitive information and more.
