Question 1

How does ZIP creation work in the browser?

Accepted Answer

This tool uses the JSZip library to create ZIP archives entirely in your browser. No files are uploaded to any server.

Question 2

Is there a file size limit?

Accepted Answer

The practical limit depends on your browser's available memory. Files up to 100 MB total should work well.

Question 3

Can I add folders to the ZIP?

Accepted Answer

Currently the tool supports adding individual files. Folder structure from file selection is preserved.

Question 4

Are my files uploaded anywhere?

Accepted Answer

No. All ZIP creation happens locally in your browser. Your files never leave your device.

Question 5

What compression level is used?

Accepted Answer

The tool uses the default DEFLATE compression which provides a good balance between speed and compression ratio.
