File renamer FAQ

Are my files uploaded to a server?

No. File contents stay in your browser. Rename, ZIP, and download all run locally. If a rename instruction is not recognized, only the prompt and a sample of filenames may be sent to the AI — never the files themselves.

What file types can I rename?

Any file type. The tool changes the filename only. Images, PDFs, Office documents, spreadsheets, archives, and other extensions all work.

How do I rename many files at once?

Add your files, write one instruction in everyday English (for example “add invoice- as a prefix”), review the preview, then download. One file downloads directly; multiple files come back as a ZIP.
