What this makes
A picture of your name in a signature face, with a light handwriting effect so it looks written rather than typed, exported as a transparent PNG at 300 DPI or an SVG. The faces here were chosen for three things a signature needs: capitals that read at a glance, joins that never break, and enough irregularity to look like a hand. Allura and Alex Brush are the most convincing; Mr De Haviland and Mrs Saint Delafield look like a hand that has signed the same name a thousand times.
Slant, weight and ink
A signature is judged on its first letter, so look at the capital of your first name and your surname before anything else. Then set the slant: a right lean of 8 to 12 degrees reads as quick and confident, upright reads as careful. Heavier weight reads as formal; a lighter ink and a little wobble read as a real pen. The preview updates as you move the sliders, and the link in the address bar keeps your settings.
Where to use it
The transparent PNG drops into a letterhead, an invoice, an email signature or a website without a white box behind it. The SVG scales to a stamp or a banner. Keep the text you typed so a later version can be regenerated in the same face. Nothing you type is stored on this site.
Not a legal signature
This is a design asset. It does not verify who you are, and pasting it into a document does not sign the document. Electronic signatures get their standing from the process around them, which records who signed, when and what; for a paper document, sign by hand. To develop a real signature, print the practice sheet, trace your name for a week, then write it fast and stop changing it.
