Why a Signature at 20KB Stops Looking Like a Signature
JPEG compression works in blocks of pixels and throws away detail it judges unimportant. A signature is mostly thin dark lines on a large white area — exactly the detail that gets discarded first. Two things fix this before you compress: scan or photograph the signature in black ink on plain white paper, and crop tightly so the white margins do not waste the 20KB budget.
How to Resize a Photo or Signature to 20KB
- Use a clean source: Black ink on white paper, photographed straight on in good light.
- Crop first: Trim the empty margins so the signature fills the frame.
- Set the target to 20KB: If the form specifies dimensions, set width and height too.
- Zoom in before uploading: At 100% zoom the strokes must still be continuous, not blotchy.
Frequently Asked Questions
My signature becomes blurry at 20KB. What should I do?
Crop the image tightly around the signature and try again. Most wasted space is blank white paper. Convert to greyscale if needed.
Is 20KB enough for a photograph, or only for a signature?
It is workable for a passport-style face photo if the background is plain. For full document pages, use the 100KB page instead.
The form says 20KB but rejects my 20KB file. Why?
Some portals compare bytes rather than KB. Target 18KB to leave a safe margin.
Does resizing to 20KB change the pixel dimensions?
Only if you ask it to. File size and pixel dimensions are separate settings.
Is my signature uploaded anywhere?
No. The resize happens inside your web browser, keeping your identity element safe.
