ALZip vs WinZip PDF Pro

ALZip is a file compression and extraction program published by ESTsoft. It handles about 40 formats, including ALZ, EGG, ZIP, LZH, TAR, and JAR, and can extract split ALZ, EGG, ZIP, RAR, and ACE archives. Listed features include encryption, split archives, command-line tools, multithreaded ZIP compression, solid and split EGG archives, and Unicode compression. In icon view, users can preview image thumbnails without extracting an archive; linked image viewing requires installing ALSee. ALZip can warn when an archive contains a suspected malicious file and extract it to a safe folder. The PC version can use ALYac to scan compressed files for risks. The product page recommends Windows 11 and 10 for PC and describes a Linux version with similar functions; an Android app is also linked. ESTsoft claims extraction speed can increase by up to 700%, with results depending on format, PC, and environment. The Personal plan costs nothing for qualifying domestic individual users using it noncommercially. Business, education, and public-sector licenses are sold separately, with prices available through the business shopping mall.

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.
