Frequently asked questions

Can I resize an image to exactly 20KB or 50KB?

Yes. Enter your target KB size and our tool will automatically adjust image quality to get as close as possible to that size.

Why is my output slightly different from the target KB?

Image compression works in increments so the output may be slightly above or below your exact target. It will always be within a close range.

What is the minimum file size I can target?

Very small targets like under 10KB may result in visible quality loss as heavy compression is needed.

Does this tool change image dimensions?

No. Only the file size is reduced through quality adjustment. Dimensions stay the same.

Which formats are supported?

JPG and PNG are fully supported. For best results with small KB targets, use JPG format.
