Bulk File Renamer
Rename many files at once with find/replace, prefix, suffix or sequence numbers - download as a ZIP.
Renaming dozens of files one at a time - photos from a shoot, exported assets, downloaded documents - is tedious and error-prone by hand. This tool lets you drop in a batch of files and apply a find/replace pattern, a prefix, a suffix, or sequential numbering across all of them at once, then bundles the renamed copies into a single ZIP for download. Originals are never touched; everything runs locally in your browser, so nothing is uploaded to rename a batch of files that might contain sensitive names.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Does it modify the original files?
No - originals are untouched. You get a ZIP with renamed copies.
Does it upload my files?
No - everything runs locally in your browser.
Can I combine multiple renaming rules?
Yes - apply find/replace alongside a prefix, suffix, or sequence number in the same pass.
Is there a limit on how many files I can rename?
No hard limit - the practical ceiling is how many files your browser can hold in memory at once.

This tool is also a REST endpoint, so you can run it in a pipeline instead of by hand. Each call costs 2 credits and needs an API key. See the API reference for every parameter.
