Signing a PDF used to mean printing it, signing by hand, and scanning it back in — a genuinely annoying loop for something that takes two seconds on paper. This tool skips all of that: draw your signature with a mouse or finger, or type your name and pick from several cursive-style fonts, then download it as a transparent PNG ready to drop into any document.
It works for contracts, invoices, forms, and anywhere else a signature image is needed digitally. The transparent background means it places cleanly over existing document text or letterhead without a white box around it, and there's no login or watermark on the free plan.
