Frequently Asked Questions

What is the maximum file size?

There is no server limit as everything happens in your browser. The only limit is your device's RAM, which typically allows processing hundreds of megabytes.

Are files uploaded to a server?

No, the ZIP archive is created entirely in your browser using the JSZip library. No data ever leaves your device — your files remain 100% private.

Can I add folders?

You can drag and drop multiple files at once. The archive is created flat without subfolders for maximum compatibility.

What compression level is used?

The tool uses DEFLATE level 6 compression, providing a good balance between reduced file size and processing speed.

What file types can I add?

All file types are accepted: images, documents, PDFs, videos, and more. There are no format restrictions.
