ZIP Creator & Extractor
Creates ZIP archives from files you drop in — with real DEFLATE compression — and opens existing ZIPs to browse and extract single files or everything at once. Nothing is uploaded anywhere.
Runs 100% in your browser — your files never leave your device.

Notes
- Compression uses the browser's built-in CompressionStream (the same zlib algorithm as desktop tools); already-compressed files like JPEGs are stored without recompression.
- Password-protected archives are not supported.
- Runs 100% in your browser — your files and data never leave your device.
