New: native 7-Zip engine with encrypted 7z, hidden file names, multithreaded compression, split volumes, and smarter folder compare. Peek opens any archive in a fast, native Mac window — browse, preview, edit, and pull out exactly what you need without unpacking everything into a folder first. Built for developers, IT, and power users who live in archives all day. No account. No subscription. No data collection. BROWSE WITHOUT EXTRACTING - Inspect contents in a clean tree view. - Search by file name or inside text files. - Preview code, JSON, images, and PDFs instantly. - Open any file in its default app — without a full extract. RIGHT FROM FINDER - Quick Actions to compress, protect, extract, or open — straight from the right-click menu. - Quick Look previews and custom thumbnails that show what's inside before you open it. NATIVE 7-ZIP ENGINE - Create and edit encrypted .7z archives, with an option to hide the file names inside. - Fast multithreaded compression (LZMA2) with advanced BCJ/ARM/Delta and PPMd filters. - Edit encrypted 7z in place — add, replace, rename, and delete without rebuilding everything. COMPARE & DIFF - Compare archives, folders, or loose files — not just compressed files. - Line-by-line text diff plus semantic diffs for config files (.env, JSON, plist, YAML). - Secrets are automatically masked, so passwords and tokens never show in plain text. - Diff dependencies and versions across package.json, Podfile.lock, Package.resolved, and Info.plist. - Ignore rules, filters, and one-click export of any comparison. EVERY FORMAT YOU'LL HIT ZIP, 7Z, RAR, TAR, TAR.GZ, TAR.BZ2, TAR.XZ, GZIP, BZIP2, XZ, ISO, CAB, LZH/LHA, Unix compress (.Z), uuencode, and ZIP-based packages like JAR, APK, AAB, IPA, EPUB, APPX, and XPI. PEEK PRO — one-time unlock, no subscription - Edit archives in place: add, replace, rename, and delete, then save without re-zipping everything. - Create and convert between ZIP, 7Z, and TAR with speed/size compression profiles. - Split archives into volumes (.001, .002, …); Peek auto-rejoins them on open. - AES-256 password protection, with passwords stored securely in Keychain. - Verify integrity with SHA-256 and export checksum reports. - Batch extract, convert, and verify many archives at once. Peek works only with the files you choose, needs no account, and collects no data.
