WinZip PDF Pro is a Windows application for editing, organizing, converting, signing, and protecting PDFs. Its editing tools add text, images, stamps, shapes, watermarks, files, and links, and can highlight or underline text. Page tools delete, rotate, reorder, and extract pages or split a PDF into new files. Conversion works between PDF and formats such as Word, Excel, PowerPoint, JPG, and PNG. Signatures may be drawn, typed, or uploaded as an image; documents can also be password-protected and assigned permissions. The maker says compression has no file-size limit and is processed locally, and the application works offline. A 7-day trial starts at installation without requiring email, a credit card, or registration. After it ends, reading PDFs remains free, but other features are locked. The Free PDF Reader plan is free and supports reading, searching text, and bookmarking pages indefinitely. The current version supports Windows 11, 10, 8, and 7. Minimum requirements include a 1.5 GHz processor, 2 GB memory, and 220 MB disk space.
