Reduce Image Size in KB — Any Target
Every form has its own number: 12KB here, 75KB there, 150KB somewhere else. Instead of hunting for a page that matches your exact limit, type the KB target below and this tool will compress your image to fit it. It always keeps the highest quality your limit allows.

Frequently asked questions
How do I reduce image size in KB without losing quality?
Quality loss is unavoidable below a certain size, but it can be minimized: the tool searches for the highest JPEG quality that fits your KB target before touching dimensions. That order — quality first, dimensions second — preserves the most detail.
What KB size should I choose?
Use the exact limit your form states. If the form gives a range like 20–50KB, enter the maximum (50) here; if your result lands below a stated minimum, run it through our increase image size tool.
Can I increase image size in KB instead?
Yes — some systems reject files that are too small. Use our increase image size in KB tool, which enlarges the file until it clears the minimum.
