Free, private, in-browser archive converter. Open a ZIP/TAR/TGZ or a single file and convert instantly — no uploads.
Drag & drop a .zip, .tar, .tgz/.tar.gz, .gz, or any single file here, or
* GZ is available for single files (not multi-file archives). To compress many files to GZ, first pack them as TAR, then choose TGZ.
All processing happens locally in your browser. Your files never leave your device.
This tool converts archives between ZIP, TAR, and TGZ (.tar.gz), and can also compress a single file to GZ — entirely in your browser. It preserves folders and filenames when working with archives.
Use it to repackage downloads, prepare deployments, or switch formats for compatibility (e.g., ZIP for Windows users, TAR/TGZ for Linux/Unix workflows).
Input: ZIP, TAR, TGZ (.tar.gz), GZ, or a single file (any type). Output: ZIP, TAR, TGZ, and GZ (single file only).
When should I use GZ vs TGZ?GZ compresses exactly one file. TGZ is a TAR archive (possibly many files/folders) that is then GZ-compressed. To gzip many files, create a TAR first (TGZ does this in one step).
What does the “Compression” setting do?For ZIP, TGZ, and GZ outputs, 0 = store only (fastest, largest) and 9 = maximum compression (smallest, slowest). TAR is uncompressed.
Are my files uploaded?No. Everything runs locally in your browser for privacy.
Can it open RAR or 7Z?Not yet. Those require a larger WASM decoder. We may add optional 7Z/RAR read support later via a lazy-loaded module.
Maximum file size?Limited by your device’s memory and browser. Large archives work best on desktop with plenty of RAM.
