How to compress an image to 20KB
TargetKB starts from a 20KB limit and finds the clearest possible JPG result below that size.
- Open the TargetKB compressor with the 20KB limit already selected.
- Upload one image or up to 10 images at once.
- Download the optimized image and check its dimensions and file size before uploading.
Why use an exact-size compressor?
Many upload forms reject files for being only slightly too large. TargetKB works backwards from your requested limit, automatically balancing image dimensions and JPEG quality instead of asking you to guess a quality percentage.
Check byte limits, output quality and format limitations if your upload is still rejected.
Frequently asked questions
Can an image look clear at 20KB?
It depends on the original dimensions and detail. Small portraits and simple graphics work best at this limit.
Can I upload multiple images?
Yes. You can compress up to 10 images in one batch.
