How an image gets down to 20 KB
Quality is lowered first, but not below a set floor, so the picture doesn't turn into blocks. If it still doesn't fit, the image is made smaller in steps until it's under 20 KB.
A phone photo will end up only a few hundred pixels across. That's normal at 20 KB and fine for a passport-style photo on a form.
If your form also gives pixel dimensions, type them in as well: the photo is resized to that size first, then saved under 20 KB. For a signature, use the Signature preset.
Frequently asked questions
Why is my 20 KB photo so small?
20 KB holds very few pixels. To fit, the photo has to be scaled down; a few hundred pixels across is typical.
How do I resize a photo to 20 KB?
Choose 20 KB as the target size. The photo is saved at the best quality that fits, and scaled down if it has to be.
How do I resize an image to 50 KB?
Choose 50 KB as the target, and add a width and height too if your form asks for exact pixels.
Can I resize an image without losing quality?
Making a photo smaller in pixels keeps it sharp. A KB target may lower quality a little to fit, and making a small photo bigger can't add detail.
