Frequently Asked Questions
Why is it downloaded as a package?
Browsers can't modify local files directly, so files are renamed and packed into a ZIP for download — extract it after.
Which rules are supported?
Prefix, sequence number (zero-padded), suffix, and string replacement, with the original extension preserved.
Can I preview the changes?
Yes, the list shows the Old Name → New Name mapping in real time.
Are files sent to a server?
No. Packing happens entirely in your browser.
