Convert Image Filenames to Lowercase in Bulk

Normalize a batch of image filenames to lowercase for web publishing and predictable URLs.

Convert Image Filenames to Lowercase in Bulk

Normalize a batch of image filenames to lowercase for web publishing and predictable URLs.

Batch Img Tools renames at export time, so the originals on your device are not renamed in place. That makes it easier to test a rule, preview the result and change it before downloading the ZIP.

What you can do

  • Filename templates and sequence numbers
  • Find/replace including regular expressions
  • Case transforms and EXIF tokens
  • Collision-safe ZIP export

One rule. Every file. One download.

Add your images above and run the whole batch in one pass — free, private, and exported as a single ZIP.
