Your files are never uploaded. Everything is processed on this device.

  2. 2Set the naming rule
  3. 3Save as ZIP
Done

🔒 Your files are never sent to an external server. Everything is processed safely inside this browser.

How to use

  1. Tap "Choose files" and select the files to rename (you can add more any time).
  2. Set the naming rule (e.g. photo_{n}), the first number, digits and order. The new names are shown below.
  3. Tap "Rename and save as ZIP" and save.

How it works

  • The selected files are renamed in one go according to the rule.
  • A browser cannot rename the files on your device directly, so the renamed files are packed into a ZIP.
  • If two names would clash, a number is added to the later one.

Notes

  • Extensions (.jpg etc.) stay as they are.
  • Your originals are not changed. Open the ZIP and use the files.
  • Characters not allowed in file names (/ \ : * ? " < > |) become "_".

FAQ

Are my files uploaded anywhere?

No. Everything is processed inside the browser on your device.

How do I get 001, 002 ...?

Set the digits to 3. Use 2 for up to 10 files, and 3 or more for 100 or more.
