Zip, unpack and find files without uploading them. Pico Zip is a simple archive tool for iPhone, iPad and Mac. Archive processing runs on your device, with no app account, ads or analytics. FREE EVERYDAY TOOLS • Create ZIP, 7z, TAR, TAR.GZ and TAR.BZ2 archives from files and folders. • Protect ZIP archives with an AES-256 password. • Extract ZIP, 7z, TAR, TAR.GZ, TAR.BZ2 and single-file GZIP archives. • Open and extract single-volume RAR / RAR5 archives, including password-protected archives when you know the password. RAR creation and multipart RAR are not supported. • Browse archive contents, search filenames and extract only the files you select. • Preview supported extracted files, then save or share your results. • Keep existing outputs: conflicting names are numbered rather than silently overwritten. OPTIONAL ONE-TIME SUPPORT If Pico Zip is useful to you, Support Pico Zip is an optional non-consumable purchase. It supports continued development and adds: • A queue for unpacking multiple archives. • One archive per input file or project folder. • Reusable format and filename-prefix presets. There is no subscription. Basic compression, password-protected ZIP creation, extraction and archive browsing remain free. Restore purchases is available in the support screen. YOUR FILES STAY LOCAL Archive creation, extraction and password handling run on your device. Pico Zip does not upload your files or passwords to a developer server or include tracking SDKs. Working copies remain in the app until removed. Purchasing and restoring use Apple's services; cloud file providers, destinations you choose and system backups may transfer files according to your settings. Requires iOS 15 / iPadOS 15 or macOS 12 or later.
