How to compress an image to 30KB
Open TargetKB with the 30KB target selected, upload your image, and download a result that fits under the limit.
- Open the TargetKB compressor with the 30KB 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
Does TargetKB change image dimensions?
It can reduce dimensions when needed to reach a very small target while preserving the best possible result.
Can I select another size?
Yes. The main compressor accepts any custom KB or MB target.
