B1 Archiver vs Bandizip

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.

Bandizip is an archiver for compressing and extracting files on Windows and macOS. It creates formats including ZIP, 7Z, ZIPX, EXE, TAR, and ISO, and extracts more than 40 formats, including RAR and RAR5. It supports multi-volume and high-capacity compression, smart extraction, and editing files inside an archive. AES-256 encryption is available, and 7Z archives can encrypt filenames. On Windows, archive scanning uses the system antivirus through Microsoft AMSI and requires Windows 10 or later with real-time protection enabled. The free Standard Edition includes ads and limited features; its malware scan is restricted to archived files smaller than 1 MB and cannot detect malware in every archive or format. Professional Edition adds a password manager, ZIP archive repair, password recovery, and image previews inside archives. It costs 30.00 USD once for one user on up to five PCs at a time. Enterprise Edition costs 20.00 USD once per single-PC license, with a minimum purchase of two. Windows support covers versions 7, 8, 8.1, 10, and 11; macOS requires version 10.13 or later.
