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.

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.
