Batch renaming photos by the date they were taken
How Nomaro renames the photos in a folder by EXIF date taken and a sequence number, with preview, conflict checks and undo.
Nomaro: Batch rename
Rename hundreds of files at once, correctly.
Open a folder, add rules in order and see each file's new name next to the current one before anything changes. Conflicting or invalid names are flagged; the last rename is undone with one click. Files never leave the device.

Key features
- Ordered rules
- Find and replace, insert text, remove characters, case, numbering, date, name from tags, spaces and characters, extension. Rules can be switched on and off and reordered.
- Live preview
- The current and new names appear side by side; unchanged and excluded files are marked. It stays smooth in folders with thousands of files.
- Conflict checks
- The same name given to two files, names that already exist in the folder, characters invalid on Windows and reserved names (CON, NUL…) are flagged; files with problems are skipped.
- Undo
- The last rename is undone with one click. Renaming happens in two steps, so swaps such as "a → b, b → a" are applied safely.
- Regular expressions
- Find and replace can use regular expressions; groups are carried into the new name with $1, $2. An invalid expression shows a warning and is not applied.
- Photo and music tags
- Capture date and camera from photos (EXIF); artist, title, album, track number and year from music can be written into the name: "03 - Artist - Title.mp3".
