How do I resize a signature for an online form?
To resize a signature for an online form, upload a photo of it, choose your exam and keep Signature selected. Fileora whitens the paper, darkens the ink, crops to the exact pixel size and fits the JPG into the KB range, often 10–20KB. Check your official notification for the exact numbers.

Black or blue ink?

Questions people ask
Can I sign on my phone screen instead?
For exam forms, sign on paper and photograph it, because many portals ask for a scanned signature.
Is my signature uploaded?
No. It stays on your device.
What if my signature file is below the minimum KB?
The tool pads the JPG so it meets the minimum without changing how it looks.
Are these sizes official?
They are the sizes most notifications for these exams have used. Rules can change between notifications, so always check your official notice and edit the width, height or KB numbers to match.
What if my file is smaller than the minimum KB?
The tool adds harmless padding data to the JPG so it meets the minimum size. The picture itself does not change.
