Does the tool read the contents of my files?

No. Only the filenames are processed. The file contents are not read or transmitted — just the names are changed when downloading.

Can I add a number sequence to all filenames?

Yes. Add a sequential number rule to append or prepend numbers like 001, 002, 003 to each filename automatically.

What if I make a mistake in the rename rules?

The preview panel shows the exact new filename for each file before you confirm. Review the names carefully before downloading.

Can I change file extensions with this tool?

Yes. Using the find-and-replace rule, you can change the extension (e.g. replace ".jpeg" with ".jpg") across all selected files.
