How to get a clear photo at 20 KB
At 20 KB there is only room for a small picture. Around 200 × 230 pixels stays sharp; a much larger pixel size has to be compressed so hard that the face turns blocky. If your form fixes a pixel size, enter it. If it only gives a KB limit, keep the picture small.
KB and pixels are different things
Pixels are the width and height of the picture. KB is how much storage the file takes. Forms usually limit both, and this tool sets both at once: it draws the picture at the exact pixel size and then adjusts JPG quality until the file fits.
Why uploads get rejected
- The file is a few KB over or under the allowed range.
- The file is PNG, HEIC or PDF when the form accepts only JPG.
- The face is too small, off-centre or in shadow, or the background is not plain and light.
- The signature is in capital letters, faint, or signed by someone else.
- A screenshot or a photo forwarded through a chat app was used, which lowers quality.
Questions and answers
Is my photo uploaded to your server?
No. The resizing happens on your own phone or computer. The picture never leaves your device.
My form needs at least 10 KB. Will the file be too small?
No. Set the minimum box to 10 and the tool keeps the file between your minimum and maximum.
