How to make a good signature file
- Sign on plain white paper with a black pen, larger than normal. Use a blue pen only if your notice allows it.
- Take the photo straight on, in daylight, with no shadow of your phone across the paper.
- Choose the photo here. The tool finds the writing and frames it.
- Check that every stroke is still there in the result. If thin lines vanish, lower the strength.
What Clean the paper does
A phone photo of white paper is really grey, and darker at one side. The tool compares each point with the paper around it, so the whole sheet turns white and the shadows go. The ink stays dark. A plain resize keeps the grey, and grey takes more space in the file.
Signatures that get rejected
Notices often name the same faults: blurred, miniature or partial signatures, capital letters where they are not allowed, and a signature that differs from the one you make in the exam hall. Write it the way you will on the day.
How do I resize a signature to 140 × 60 pixels?
That is the size this page starts with. Choose your signature photo and download the result. It also lands between 10 KB and 20 KB.
Can I make a signature on my phone?
Yes. Sign on paper, take a photo, and do the rest on this page in your phone’s browser.
What if my signature comes out too thin?
Sign again with a thicker pen, or lower the strength. Thin pen lines can fade when a large signature is shrunk into a small box.
Does it remove the background?
It turns the paper white. The result is a JPG, which has no transparent background, because that is what forms ask for.
