Reduce a photo when a portal has a low maximum size.
How to compress an image to 50KB
A successful result is at or below 51,200 bytes (50 × 1,024), not padded to exactly 50KB. If your portal requires fewer than 50,000 bytes, use the 48KB option above. Check the downloaded photo for readability and required dimensions.
- The compressor on this page starts with 50KB selected. Change it only if your upload requires another limit.
- 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 I make an image smaller than 50KB?
Yes. Change the target directly in the compressor above. Smaller limits may reduce dimensions or detail.
Why does a 50KB image look less detailed?
A small limit can require lower JPEG quality or fewer pixels. Keep your original and check that faces and text remain readable before uploading.
Can I process more than one image?
Yes. Upload up to 10 images and each will be compressed to under 50KB.
