ZeroPDF

ZeroPDF is a desktop PDF viewer and editor for Windows. It reads documents with continuous scrolling and thumbnails, lets you annotate with highlights, notes, shapes and freehand drawing, and edits the original PDF text while keeping the document's font, size and colour. It also fills AcroForm fields and flattens them on export, runs offline OCR on scanned pages, opens password-protected PDFs, saves AES-256 encrypted copies, extracts and merges pages, crops margins, adds page numbers and headers, manages bookmarks, metadata and watermarks, prints, and converts between PDF and Word or from images to PDF. The interface is translated into 23 languages, including English and Spanish, with Arabic shown right to left. It is free software under the MIT licence, with no accounts, no telemetry and no Internet connection required.
