Frequently Asked Questions

How do I create a ZIP file online?

Upload the files you want to bundle using the upload box, then click "Create ZIP". A single .zip file containing all of them is generated and ready to download.

Can I password-protect the ZIP file?

Yes. Tick "Protect with a password" before creating the archive and enter a password. The ZIP is encrypted with AES-256, one of the strongest ZIP encryption standards.

Can I create a ZIP without a password?

Yes, password protection is optional. Leave the checkbox unticked to create a standard, unencrypted ZIP file.

Are my files uploaded to a server?

No. The ZIP is built entirely inside your browser using zip.js, a JavaScript library. Your files never leave your device.

Is there a limit to how many files I can add?

There is no fixed limit. Your browser's available memory is the practical limit. Most modern devices handle hundreds of files comfortably.
