Optimize up to 10 images before you start sharing.
How to compress an image to 500 KB
Use the 500KB starting target for WhatsApp sharing, or lower the target when you need a smaller file.
- Open the TargetKB compressor with the 500 KB 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 send images to WhatsApp?
