No. Once files are downloaded with new names, the original names are not stored. Always use the preview to verify changes before applying.
Yes. The tool renames files regardless of type. It only changes the file name, not the file contents or extension (unless you explicitly include the extension in your rename pattern).
There is no hard limit, but very large batches (thousands of files) may be slower depending on your browser and device.
