What a 20KB image looks like

20KB is very small. A JPG of that size is typically a small photo around 300 to 450 pixels wide at moderate quality. It is fine for a face on a form but not for a full-scene photo you want to print.

Signatures fit 20KB easily, because they are mostly plain white with a few dark lines. A signature scan of about 300 to 600 pixels wide is often only a few KB.

Where 20KB limits appear

Exam registration portals and some application forms often ask for photos and signatures in the 10 to 50KB range, and 20KB is a common cap for signatures in particular. Always follow the size, pixel dimensions and format stated on the form you are filling.

How the tool fits it into 20KB

The tool saves as JPEG and searches for the highest quality that fits, trying values between 0.95 and 0.5. If even the lowest quality is too big, it reduces the width and height in 10 percent steps until the file is at or under 20KB. When it says done, the image fits.

If it cannot get under 20KB, it tells you and gives you the smallest result it made. This is rare for photos and signatures, but can happen with very detailed images.

Tips for a clear 20KB photo

Crop to your face and shoulders first, so no pixels are wasted on the room behind you. Use a plain, light background; busy backgrounds take up space. Avoid PNG for photos, since PNG files are much larger. For a signature, sign in dark ink on white paper and crop tightly around it.

Questions, answered

How do I reduce my signature to 20KB?
Scan or photograph it on white paper, crop tightly around the signature, and add it here. Signatures usually fit 20KB with little loss.
Why does my 20KB photo look blurry?
At 20KB the image has to be small and fairly compressed. Crop to the face first and use a plain background, so the available space goes to your face.
What size in pixels is a 20KB photo?
Typically around 300 to 450 pixels wide at moderate quality, though it depends on the photo. Plain backgrounds allow larger dimensions.
The form needs exact pixel dimensions and 20KB. What do I do?
Crop to the right ratio, resize to the exact pixels with the resize tool, then set the maximum size to 20KB.
Can I keep it as PNG?
Photos as PNG rarely fit 20KB. The tool saves JPG, which is much smaller for photos and accepted by most forms.
