Use this page when something refuses an image larger than 20 KB. The preset sets the target to 20 KB (20480 bytes) and lets the tool choose the quality and, if needed, the size.

At this size the budget is tight. A typical photo can hold only about 137 thousand pixels, roughly 430 × 320, so expect a small picture. That is fine for a signature, a thumbnail or a form photo, but not for a large print.

What fits in 20 KB

File size depends on both pixel count and how much detail the picture holds. The estimates below use rules of thumb for photos saved as JPG at web quality (roughly 0.08 to 0.3 bytes per pixel); your own result will vary with the image.

A typical 12-megapixel phone photo is around 3.5 MB, so reaching 20 KB means roughly a 179× reduction. Most of that comes from reducing the pixel count, not only from lowering quality.

How to stay under 20 KB with the best quality

• Crop first. Removing empty background means the same 20 KB is spent on the part of the picture that matters.
• Expect visible softness on detailed images. If a form lists both a size limit and minimum pixel dimensions, check them against the table above before you start.
