What is bulk image renaming?

Bulk renaming means changing the filenames of many images in one operation instead of renaming them one by one. If you're a photographer, e-commerce seller, or social media manager, you probably deal with hundreds of images that need organized, consistent names. Bulk renaming saves time and prevents errors.

Rename options available

  • Sequential numbering — rename files as 1.jpg, 2.jpg, 3.jpg or with zero-padding: 001.jpg, 002.jpg
  • Alphabetical sequence — rename as a.jpg, b.jpg, c.jpg through zzz.jpg
  • Custom pattern — combine tokens like {prefix}-{index}-{name}
  • Prefix & suffix — add text before or after the base filename
  • Find & replace — replace part of a filename with new text
  • Space cleanup — remove spaces or replace with hyphens/underscores
  • Case conversion — force lowercase, UPPERCASE, or Title Case

Frequently Asked Questions

Open the Batch File Renamer, drag and drop your images, configure the rename settings (pattern type, numbers, prefix, etc.), click "Apply & Preview", and then download all files as a ZIP. It's free, requires no account, and runs entirely in your browser.
Yes. The Live Preview panel updates in real time as you type or change settings. Every original filename is shown side-by-side with its renamed version so you can confirm everything looks right before committing to a download.
No. Only the filename changes. The image content, quality, metadata, and format remain completely untouched. The tool simply copies the file in memory and sets a new filename when you download it.
