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.
