Rename hundreds of files in one go.

A focused, scriptable bulk renamer for Android. Pick the files, type the rule, see the diff before you commit. No cloud, no account, no telemetry.

What you get

Live diff preview — see every rename before applying
Find & replace, sequence numbering with pattern hints, prefix/suffix add & trim, case conversion
Collision detection — the engine won’t overwrite a file that already exists at the target name
Real File.rename on Android 11+ (not a SAF copy-and-delete)
Works fully offline once installed

How your data is handled

Bulk Rename operates entirely on your device. It needs broad file access so it can rename files outside the app sandbox — but it never reads, copies, or transmits the contents of those files. The only data that leaves your device is the standard ad request to Google AdMob.
