ZIP Creator
Bundle multiple files into a single ZIP archive. 100% browser-based via JSZip — your files never leave your device.
How ZIP Creator works
Add as many files as you like — one drop or multiple. Duplicates are skipped automatically.
Store (fastest, no compression), Fast, Balanced, or Best (smallest file, slower).
JSZip builds the archive entirely in your browser. Live progress bar shows completion.
Frequently asked
Is my file uploaded to a server?+
Never. Everything runs in your browser via JSZip. Perfect for private or confidential files.
How big a ZIP can I make?+
Practically limited by your device's memory. Modern laptops handle 1 GB+ archives easily. On mobile, keep it under 200 MB total.
Can I add folders?+
The current tool bundles files. To include a folder structure, drag files from within your folder — subfolder names aren't preserved (browsers restrict directory metadata for security).
What compression algorithm is used?+
DEFLATE (the same algorithm used by every ZIP tool). "Store" mode packs files without compression for fastest speed.
