Frequently Asked Questions
How does the {n} pattern variable function?
The {n} placeholder is a dynamic structural variable. It is replaced by a sequential integer block starting from your "Index Start" value. For example, "asset_{n}" will resolve to "asset_1.png", "asset_2.png", and so on.
Can I perform a bulk extension migration?
Yes. By populating the "Extension Override" field, you can force all staged files to adopt a new format (e.g., converting .jpeg to .jpg). Leave this field empty to preserve the original metadata of each source file.
Is my file data secure during the renaming process?
Absolutely. All string manipulation and ZIP bundling occur strictly within your browser's local sandbox. No binary data is transmitted to our infrastructure, ensuring a zero-leakage security posture.
