Resize image to 20KB online: what to know

20 KB is the limit you meet most often on signature uploads, and sometimes on small ID photos. It is tiny, so the tool works in two steps: it reduces the pixel size a little, then lowers the JPEG quality until the file just fits under 20 KB.

Dark ink on white paper shrinks very well. A detailed colour photo does not, because there is more to squeeze out. If your result looks blurry, start from a smaller or better lit original, or check whether the form really needs 20 KB.

Tips

Questions

Why is my image still above 20KB?

The picture is probably very large or very detailed. Lower the width and height, then resize again.

Will a 20KB signature look clear?

Yes, if it is dark ink on white paper. Photos lose more detail at this size.
