How to use
Frequently asked questions
You drop the files in, set a naming pattern, and the tool applies the same rule to all of them. For example: add "Note_" as a prefix plus the current date — "photo.jpg" becomes "Note_2026-07-28_photo.jpg". The result comes as a ZIP file with everything renamed.
You can add a prefix and a suffix, insert automatic numbering (with a custom start), include the current date in several formats, and use find-and-replace to swap parts of the original name. All the options can be combined.
No. The tool downloads a copy of the already-renamed files inside a ZIP. Your original files stay untouched on your device.
Yes — renaming is purely about the file name, so it works with photos, PDFs, videos, audio, Word documents, spreadsheets and anything else. The extension is preserved automatically.
You can select many files at once. If you want to organize an entire folder, select all the files in it (Ctrl+A / Cmd+A in the picker) and drop them here.
No. The renaming and the ZIP packing happen entirely in your browser. No file leaves your device.
