Question 1

Are my files uploaded?

Accepted Answer

No. ZIP creation uses the JSZip library running entirely in your browser. Your files never leave your device.

Question 2

How many files can I add?

There is no hard limit. The practical limit depends on your device memory and the total uncompressed size.

DEFLATE compression at level 6, the same algorithm used by most ZIP tools.

Question 4

Can I add more files after the initial drop?
