B1 Archiver vs WinZip PDF Pro

B1 Free Archiver creates and extracts archives, with desktop software, an Android app and an online archiver. The desktop application creates B1 and ZIP archives and supports almost 40 formats, including RAR, RAR5 and 7z. The online tool extracts files from B1, ZIP, RAR, 7z and other archive types. On Android, B1 also works as a file manager. The B1 format supports password protection using 256-bit AES encryption, and the desktop archiver checks archive integrity with Adler-32 before unpacking. B1 says files uploaded to its online archiver are deleted a few minutes after the page is closed. Its privacy policy says it does not knowingly collect identifying personal data, though it may collect non-personally identifiable server information such as IP address and browser type. The policy also says app and device usage data, including location and network performance, may be collected for anonymous ad-related use in B1 apps. Support is by email and in English only. B1 is free for personal and commercial use, with no registration.

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.
