About 20KB
Sign with a dark pen on plain white paper, photograph or scan it in even light, crop tightly around the signature, then compress. Also check whether the portal sets a width and height in pixels.
For scale, 20KB is about 0.02MB. A typical 3MB phone photo has to shrink roughly 154 times to fit, so expect lower resolution and some softness. Cropping first keeps more detail.
Tips for best results
Job and exam portals commonly ask for a scanned signature under 20KB. Crop the white space around your signature before compressing for the best result.
