The fastest way to sign a PDF online

Most 'sign PDF' tools force you to register, wait for an email, or upload your document to a stranger's server. This page skips all of that. The editor runs entirely in your browser, so signing a contract, offer letter, or invoice takes about 30 seconds — start to finished PDF.

Three ways to sign

Choose whichever matches how your signature normally looks on paper. Every option produces a crisp, transparent overlay that sits on top of the PDF instead of a blurry pasted image.

  • Draw — sketch your signature with a mouse, trackpad, or touchscreen.
  • Type — pick from handwriting-style fonts (Caveat, Dancing Script, Great Vibes, Pacifico).
  • Upload — bring in an existing PNG or JPG and remove the white background automatically.

Is an electronic signature on a PDF legal?

For everyday business documents, yes. The US ESIGN Act and UETA, the UK Electronic Communications Act, EU eIDAS, and Canada's PIPEDA all recognise electronic signatures on standard agreements. A drawn or typed signature placed on a PDF and shared with the counterparty is treated the same as an inked signature for most commercial purposes. When in doubt about a specific document (wills, notarized deeds), check the local requirement.

Frequently asked questions

Is signing a PDF here legally binding?+

In most countries — including the US (ESIGN Act, UETA), UK, EU (eIDAS simple electronic signatures) and Canada — a typed or drawn signature on a PDF is enforceable for standard business documents such as offers, NDAs, invoices, and employment paperwork. Some regulated documents (wills, certain real-estate filings) still require a qualified or notarized signature.

No. There is no signup, no email, and no payment. Open the page, drop your PDF, sign, and download.
