How to compress an image to 80KB
TargetKB starts with an 80KB maximum and automatically finds the clearest JPG result below the limit. It can also read PNG, WebP, and HEIC images when your browser supports them.
- Open the TargetKB compressor with the 80KB 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.
