Frequently Asked Questions
Compression?
This uses STORED (no compression) for browser-friendly speed. Output is bigger than a DEFLATE ZIP but ~5× faster.
Folders?
Relative paths preserved from webkitRelativePath.
How do I use the ZIP Builder?
Just type your numbers. The answer shows up right away — there is no button to press. Change anything and it updates by itself.
Does it cost anything or need an account?
No. The tool is completely free, there is no account to create, and it keeps working offline after the page first loads.
Is anything I type uploaded?
No. The tool works entirely on your device, so the values you enter never leave your browser.
