Raise a compressed signature into a required KB range instead of compressing it even further.

Fix a signature that became smaller than the form allows.

Some portals reject files for being too small as well as too large. Batch Img Tools can pad a JPEG to meet a minimum KB target while keeping the maximum limit editable.

What you can do

  • Minimum + maximum KB
  • JPG range validation
  • Editable dimensions
  • Batch export

One rule. Every file. One download.
