Frequently Asked Questions
What happens to my image data?
Renaming, HEIC-to-JPEG conversion, and ZIP creation run in your browser. Your files are not uploaded to a processing server.
How does the sequential index counter work?
Use the [index] variable. To add padding, write a colon followed by the width (e.g. [index:3] produces 001, 002 etc.). It increments starting from 1 in the order of files listed in the queue.
Are invalid characters automatically sanitized?
Yes. Slashes, asterisks, brackets, and other restricted filename characters are converted to underscores automatically.
