Increase Image Size in KB
It sounds backwards, but many portals reject photos for being too small — a 9KB file fails a "minimum 20KB" rule just as surely as a 5MB file fails a maximum. This tool re-renders your image at larger dimensions and higher quality until the file size clears the minimum you enter.

Frequently asked questions
Why would a form reject a photo for being too small?
Minimum sizes are a crude quality check: a 5KB photo is usually too compressed or too tiny to verify. Systems enforce a floor so reviewers receive usable images.
Does increasing KB improve my photo's quality?
No — enlarging cannot recover detail that was never captured. It makes the file bigger and dimensions larger so validators accept it, and it avoids adding junk data, but the visible quality stays roughly what your source had.
My file needs to be between 20KB and 50KB. Which tool do I use?
Run this tool with minimum 20 — then check the result stays under 50KB; the spec stamp shows the output size instantly. If it overshoots, compress with the 50KB page instead.
