Frequently Asked Questions
How does the {n} pattern work?
The {n} placeholder is replaced by a sequential number starting from your specified "Start At" value. For example, "photo_{n}" becomes "photo_1.jpg", "photo_2.jpg", and so on.
Can I change file extensions?
Yes. Enter a new extension (e.g., "png") in the extension box to apply it to all files. Leave it blank to keep original extensions.
Is it safe to upload sensitive files?
Your files never leave your computer. The renaming and ZIP creation happen entirely in your browser using JavaScript.
