Good to know
Crop tightly around the signature before resizing; extra white space wastes pixels.
Forms often give pixel dimensions for signatures as well. Enter width and height if yours does.
Check the official notification for ink colour and size rules.
Questions
What size should a signature be?
Use what your form's notification says. Many forms use a range such as 10–20 KB, which is the default here.
Is my signature uploaded anywhere?
No. It is processed on your device only.
The signature looks faint. What can I do?
Retake the photo in brighter light with a darker pen. Avoid shadows on the paper.
Can I set pixel dimensions?
Yes. Enter width and height and the image is cropped to that shape.
Is it free?
Yes, free with no signup and no watermark.
