What is Create ZIP Online?

ZIP is the most widely supported archive format: it bundles many files into one and compresses each of them with Deflate. This tool builds a standard ZIP with the zip.js library entirely on your device, so private documents never travel to a server.

You can name the archive, choose between Store (no compression, fastest), Fast, Normal or Best compression, and keep folder paths when your browser provides them for a dropped folder. Duplicate file names are renamed automatically and file dates are preserved. The total input is limited to 500 MB.

How does it work?

  1. Drop several files (or a folder in browsers that support it) on the drop zone.
  2. Set the ZIP file name and the compression level; keep the folder structure if you want it.
  3. Check the list of entries and the size before and after compression.
  4. Download the .zip file.

Common use cases

  • Bundling several documents into one attachment for an e-mail or upload form.
  • Zipping a small project folder to share it without installing archive software.
  • Creating an uncompressed (Store) archive of already-compressed media for a single download.
  • Packing test fixtures or logs for a bug report.

Examples

Drop your files, pick a compression level and download a single .zip built right in your browser.

Privacy

Create ZIP Online runs entirely in your browser. The text or files you provide are processed on your device and are not uploaded, logged or stored on our servers.

Limitations

The archive is not password-protected or encrypted: anyone with the file can open it. Files that are already compressed (JPEG, MP4, ZIP) hardly shrink. Maximum 500 MB of input in total.

Frequently asked questions

Are my files uploaded to a server?

No. The ZIP is created in your browser with JavaScript; the files never leave your device.

Which compression level should I choose?

Normal is a good default. Fast saves time on large files, Best squeezes text and code a bit more, and Store just packs files without compressing them.

Can I protect the ZIP with a password?

Not in this tool: it creates standard, unencrypted ZIP files. Use an encryption tool if the content is sensitive.
