How to rename files

  1. Upload your files - drag and drop or browse. Any file type works: PDFs, images, spreadsheets, Word docs.

  2. Add a field - choose whether it goes at the start (prefix) or end (suffix) of the filename, give it a label and a value. For example: prefix → client → "Pulsify", or suffix → status → "APPROVED".

  3. Pick a separator - underscore, hyphen, dot, or space between parts.

  4. Download - each file downloads instantly with its new name. Nothing is uploaded to a server.
