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.

Files

File contents stay in your browser. Rename, ZIP, and download run on your device. File contents are not uploaded to our servers and are not used for advertising.

Rename instructions

Simple instructions are handled in the browser. If an instruction is not recognized, only that instruction and a sample of filenames may be sent to Google Gemini so a preview can be generated. File contents are not included.
