🏷️Bulk Image Renamer

Rename a batch of images at once. Combine placeholders like sequence numbers and dates into your own naming pattern, then download the renamed files as a ZIP.

Your images are never sent to a server (processed in your browser)

Choose images (multiple allowed)
Naming pattern

Example: photo_{n} gives photo_001.jpg, photo_002.jpg… (the original extension is added automatically. Pressing a button inserts the placeholder at your cursor.)

How to use

  1. Choose the images you want to rename (multiple allowed).
  2. Enter a naming pattern, combining placeholders like {n} and {date} as you like.
  3. Check the new names in the preview list, then press "Rename & download ZIP."

Why the browser can't rename files directly

Browsers can't rename files already on your device (that's a security restriction). Instead, this tool creates copies with new names and bundles them into a ZIP — extract the ZIP and the renamed files are ready to use.

{n} becomes a sequence number, {date} becomes today's date, and {w}/{h} become the image's width and height. If two files would end up with the same name, a number is automatically appended to keep them unique.

FAQ

Are my images uploaded to a server?
No. Renaming and ZIP creation both happen entirely in your browser.
Can I change the file extension?
No — since the file's actual format doesn't change, the original extension is always kept. Use the Image Format Converter if you want to change the format itself.
Some images would get the same new name.
A number gets appended automatically to keep names unique. Including {n} in your pattern avoids this happening in the first place.
What determines the order of the original files?
The order you selected them in. Reselect the files if you want a different order.
