Bulk File Renamer
Rename many files at once with prefix, suffix, find & replace, numbering and case options.
Browsers cannot rename files on your disk. You get a ZIP with the renamed copies instead.
Rename hundreds of files in one go
You don't need to rename files one by one to organise holiday photos as 'Rome-2026-001.jpg', name product images by SKU or clean unwanted text from a batch of files.
Renaming options
- Add a prefix and suffix
- Find and replace
- Numbering with a start number and digit count
- Upper and lower case conversion
- 'Clean names' to make names URL- and system-friendly
Preview and ZIP
See every new name in a live preview before downloading. Name collisions are resolved automatically. Browsers can't rename files on your disk for security reasons, so renamed copies are downloaded as a ZIP archive.
How to use Bulk File Renamer
- Choose the files to rename.
- Set the prefix, suffix, find & replace and numbering rules.
- Check the new names in the live preview.
- Download the renamed files as a ZIP.
Why use this tool?
Organise files in minutes without installing software; your files are never uploaded.
FAQ
Why do I get a ZIP instead of renamed files on my disk?
For security, web pages can't rename files on your computer, so renamed copies are packed into a ZIP.
Are file extensions kept?
Yes, rules apply to the file name and extensions are preserved.
What if two files end up with the same name?
Collisions are resolved automatically so every file gets a distinct name.
