Safety before extraction
Archive paths are checked for traversal, absolute locations, misleading double extensions, control characters, executable content and extreme declared expansion ratios.
Create, inspect, edit and extract ZIP archives without sending their contents to Pagan Earth or an online conversion service.
This tool reads and writes classic ZIP files with browser APIs. It does not upload entries, execute files or consult an online reputation database. Archive warnings are structural clues, not an antivirus verdict.

Archive paths are checked for traversal, absolute locations, misleading double extensions, control characters, executable content and extreme declared expansion ratios.
Classic single-disk ZIP archives using Store or Deflate are supported. Encrypted entries, multi-disk archives, ZIP64 and uncommon compression methods are reported but not silently guessed.
Creating or rebuilding an archive necessarily reads entry data in the browser. Very large archives may exceed your device memory even though nothing is uploaded.
