Four archive tools, one standard

UnpackNest has four archive tools: RAR, ZIP, 7z and TAR/GZ. Each one runs in your browser and blocks unsafe paths. Each one is tested on desktop and mobile before release, and the guides explain what to do when a file will not open.

Available

ZIP Extractor

Open ZIP files (Store, Deflate, ZIP64), preview the contents and extract selected files.

Available

7z Extractor

Open 7z archives, including password-protected and split .7z.001 sets.

Available

TAR / GZ Extractor

Open .tar, .tar.gz, .tgz and single .gz files.

Built around the file, not the upload

01

Local processing

Archive bytes are processed in your browser. The RAR extraction flow does not require uploading your file to UnpackNest.

02

Safety checks

Traversal paths, links, encrypted entries and unsafe output conditions are blocked instead of silently rewritten.

03

Clear results

See the archive type, entries and blocked items before extracting anything.
