Compress Signature to 40 KB
A 40 KB ceiling leaves a bit more room for clarity than very tight limits. Preselect it here when your form allows up to 40 KB. Still verify the number on your official notification before you apply.

FAQs
Should I always use the full 40 KB?
No need. Under the limit is enough. Extra KB is only useful if it keeps the signature clearer.
Colour vs black-and-white?
Follow the portal. Greyscale or high-contrast black on white often compresses cleaner for signatures.
What if compression stops above 40 KB?
Crop empty margins, reduce dimensions if allowed, and try again. Huge source files may need a smaller pixel size first.
Is this for left-hand / right-hand signatures?
Yes — the tool only cares about the image file. Sign as your exam instructions require.
