PNG vs SVG signatures: which to use and when

When you export a signature you'll meet two formats: PNG and SVG. They look identical on screen, but they're built differently — and that difference decides which one you should reach for.

PNG — the everyday choice

A PNG is a raster image: a grid of pixels, with transparency. It's the right pick for almost everything:

• Email signatures and footers
• Dropping onto documents, contracts and photos
• Social posts and the web

signaturelogo.co exports a transparent PNG at high resolution, so it stays sharp on normal screens. The only catch: because it's made of pixels, blowing it up far beyond its native size will eventually soften the edges.

SVG — for scale and print

An SVG is a vector: it stores the signature as mathematical paths, not pixels. That means it scales to any size with perfectly crisp edges — from a business-card monogram to a wall-sized print — and the file stays tiny.

Rule of thumb: PNG for screens and documents, SVG when something will be printed large or resized often.

Drawn signatures export as SVG today. Vector export for typed and handwritten signatures is part of the upcoming Pro tier, and a commissioned signature is delivered as vector files you fully own.

So which should you pick?

For the vast majority of uses — email, PDFs, the web — a transparent PNG from the studio is exactly right, and it's free. Reach for SVG only when you specifically need limitless scale or print-shop crispness.
