Frequently Asked Questions
How does batch renaming work?
Add your images, choose a naming pattern, and the tool renames every file in one pass — then you download the renamed set.
Can I use a custom prefix and numbering?
Yes. Set a custom prefix and the numbering style — like "vacation-01", "vacation-02" — so every file gets a consistent, sortable name.
Does it keep the original files?
Your originals are never modified. The tool produces renamed copies you can download, so nothing is overwritten.
Is it free? Are my images private?
Yes. Free with no sign-up, and all processing happens locally in your browser — your images never leave your device.
