Text replacement

Find and replace text in file names

Use a simple find-and-replace rule when file names are already close to correct but contain repeated noise. Renamio previews every result before files are changed, so you can catch unsafe replacements early.

Best for

Use this when many files share the same unwanted text, spacing, prefix, or duplicate marker and you want one controlled replacement.

Yes. The replace rule supports replacing all matches, only the first match, or only the last match.

Can I keep file extensions unchanged?
