Signature Generator: Draw or Type Online

Three ways to make your signature

• Draw: sign in the box with a mouse, a finger or a stylus. Undo (or Ctrl+Z) removes the last stroke and Clear starts over; Undo also brings a cleared signature back.
• Type: enter your name and pick one of five script fonts: Dancing Script, Great Vibes, Sacramento, Herr Von Muellerhoff and Mrs Saint Delafield. Each option shows your own name, and a size slider sets how large it is.
• Upload photo: sign a sheet of white paper, photograph or scan it and open the picture. The paper is removed and the ink kept, as a transparent PNG.

Choose black or blue ink or any colour for all three, then download a PNG with a transparent background or an SVG vector file. Both are trimmed to the ink with a little padding, so they drop neatly onto a signature line.

Tips for each method

• When drawing, sign at your normal speed. Natural line width thins fast strokes and thickens slow ones, like a ballpoint; a stylus (Apple Pencil, Surface Pen, S Pen) uses pen pressure instead. A finger on a phone usually looks better than a mouse.
• For a photo, use daylight or even lighting, fill the frame with the signature and keep the edge of the paper and the table out of the picture. A dark pen gives the cleanest result.
• Some offices ask for blue ink, because it makes an original easy to tell apart from a black-and-white copy.

How the photo cleanup works

Phone photos of paper are never evenly white: one corner is in shadow, the other catches the light. So the tool first estimates the paper’s brightness around every point, from the brightest pixels in small blocks, smoothed across the page. Each pixel is then compared with its own local paper, which removes shadows that a single threshold would turn into ink. Paper cut-off sets how dark a pixel must be, relative to the paper, to count as ink. The automatic value starts from Otsu’s method, which splits the brightness histogram into its two most distinct groups, and leans a little towards the paper so light strokes survive. Lower it if paper texture shows, raise it if thin strokes break up. Tiny isolated specks (dust, grain, JPEG noise) are removed, and the result is cropped to the ink. The ink can be recoloured or keep its own colour.

PNG or SVG?

The PNG of a drawn or typed signature is drawn at twice its on-screen size by default; choose 3× or 4× for large prints. Turn on White background if an app shows transparent areas as black. A typed signature’s SVG holds the letters as outlines, so it needs no font installed. Photos have no SVG, because they are pixels.

Can I use it to sign documents?

Many legal systems accept electronic signatures for everyday agreements: the US ESIGN Act and the EU eIDAS Regulation both say a signature cannot be denied legal effect just because it is electronic. Some documents, such as wills or notarised deeds, still need ink or a certified digital signature, so check what the recipient accepts. This is general information, not legal advice.
