Questions
What is a 20 KB limit usually for?+
Scanned signatures, thumbprints and very small ID photos on government and exam forms.
Why did my photo get smaller in pixels?+
A full phone photo can’t reach 20 KB at a clean quality, so it is scaled down until it fits at 70% quality or higher. Forms at this size expect a small picture anyway.
How can I keep a signature readable at 20 KB?+
Crop tightly around the signature first, so the pixels go to the ink, not empty paper.
Are my photos uploaded?+
No. The photo is compressed to 20 KB in your browser and never leaves your device.
