Find and replace in filenames

Find a piece of text in many filenames and replace it, for example "IMG_" with "holiday-" or "copy of " with nothing. It works as plain text or, with "Use regex", as a pattern. You see the result for every file first, and nothing is uploaded.

How to find and replace in filenames

  1. 1Drop your files in, or choose a folder
  2. 2Fill in "Find" and "Replace with"
  3. 3Check the table, then rename or download
  4. Your files with the text swapped in every name.

What happens to your files

  • Every match changes.All occurrences in a name are replaced, not just the first.
  • Plain or regex.Tick "Use regex" when you need a pattern instead of fixed text.
  • Nothing is uploaded.Renaming happens in your browser, on your own device.

What you can do

  • Replace fixed text in every name, or leave "Replace with" empty to delete it.
  • Tick "Use regex" to match a pattern. A broken pattern shows "That regex has a syntax error." instead of crashing.
  • Mix it with the other options on the page, such as numbering or a new case.
  • Rename in place in Chrome or Edge on a computer, with Undo, or download renamed copies as a ZIP.

Good to know

  • The search covers the name without its extension. To change the extension use "New extension".
  • Matching is case-sensitive. "img" will not find "IMG".
  • If two files would end up with the same name, they turn red and saving is blocked until you fix it.

Questions

How do I remove a word from many filenames?

Type it in "Find" and leave "Replace with" empty. Every match in every name is deleted.

Is the search case-sensitive?

Yes. Type the text exactly as it appears, or use a regex such as [Ii][Mm][Gg].

Can I use regular expressions?

Yes, tick "Use regex". It uses JavaScript regular expressions and replaces every match in each name.
