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)
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.)
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.
