Is it private and secure?
Your privacy is built in. Batch Image Renamer does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.
Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.
You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

Frequently asked questions
Does renaming change my images?
No. The original files are re-packed into a ZIP without any re-encoding, so image quality and format are exactly preserved — only the filenames change.
How does auto-numbering work?
Enable auto-number, choose a starting value and digit padding (e.g. 001, 002), and a sequential number is appended to each file in order.
Can I combine rules?
Yes. Prefix, suffix, find-and-replace, lowercase and numbering all apply together, and the live preview shows the resulting name for every file.
