Sign PDF — Free Online Tool

Signing a PDF used to require printing it, signing with a pen, scanning it back in, and emailing the result. That workflow still exists everywhere, and our sign tool kills it. Three signature modes are supported. Type a name in one of seven handwriting-style fonts (Dancing Script, Great Vibes, Pacifico, Allura, and others), and it lands on the page rendered exactly as a handwritten signature would. Draw your signature on a touchscreen or with a mouse, with pressure-sensitive strokes and a smoothing pass that mimics ink flow. Or upload an existing scanned signature as PNG/JPG — the tool keys out the white background automatically so the strokes blend onto the page. Once placed, drag to position, resize from eight handles (corners and edges), and rotate freely. The signature embeds as a vector path where possible (typed and drawn) or as a transparency-keyed image (uploaded), so it stays crisp at any zoom. The output PDF is otherwise byte-identical to the input apart from the added signature annotation. Compared to Adobe Sign or DocuSign, our tool is free for ad-hoc signatures and runs entirely server-side — no DocuSign account, no email round-trip, no chargeable envelope. For legally-binding e-signatures with audit trails you still need a dedicated service; for everyday paperwork, this is faster.
