Compress Images to 15 KB in Bulk

Compress multiple images toward a 15 KB file-size limit in one browser batch, with resize and format controls available when quality alone is not enough.

Batch-compress images for a 15 KB upload limit

Forms, portals, CMS systems and messaging platforms often reject files above a fixed size. This preset starts with a 15 KB target so you do not need to tune each image manually.

Batch Img Tools first searches for a usable encoding quality. If the file still cannot meet the ceiling, it can reduce dimensions rather than quietly exporting an oversized result.

What you can do

  • Target 15 KB across a batch
  • Resize and compress in one pass
  • Choose JPG or WebP output
  • Export all accepted variants in one ZIP

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.
