How to use the bulk file renamer

  1. Add the files — photos, documents, music, anything.
  2. Build the new name with a pattern such as Holiday-{n} or {date}_{name}, plus find & replace and letter case.
  3. Check the live preview and download everything as one ZIP.

Give a folder of camera photos meaningful names, number scanned pages in the right order, or clean up spaces and capital letters before uploading files to a website. The preview shows every new name before you download, duplicates are numbered automatically and characters that Windows does not allow are replaced. Files are packed without recompression, so the ZIP is created in a moment and quality is untouched.
