7-Zip vs WinZip PDF Pro

7-Zip is a file archiver for Windows, Linux, and macOS, offered at free with no registration or payment required. It creates and extracts 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM archives, and can extract additional formats such as RAR, ISO, and VHDX. The 7z format uses LZMA and LZMA2 compression, and AES-256 encryption is available for 7z and ZIP files. Other listed capabilities include split archives, archive repair, portable use, and command-line tools. The Windows version includes Shell integration, a file manager, a command-line version, and a FAR Manager plugin. The software is open source; most code is under the GNU LGPL, with some under BSD licenses and an unRAR restriction applying to some parts. The maker says it can be used in commercial organizations without payment. It is localized in 87 languages. Developers can use the LZMA SDK, which includes documentation, samples, headers, libraries, and tools for applications using LZMA compression.

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.
