The fastest way from "please sign" to "signed"
The print-sign-scan routine wastes fifteen minutes and produces an ugly, heavy scan. Signing in the browser keeps the document digital: the original stays crisp, the file stays small, and the signature lands exactly where you put it.
Two ways to provide a signature. Drawing works well on phones and tablets, where a finger or stylus produces a natural line. Uploading suits people who keep a good photo of their paper signature: light background pixels are stripped automatically, so the signature blends into the page instead of sitting in a white box.
What this tool does and does not do
This tool places a visual signature image into the PDF, which is how the vast majority of everyday contracts, consents, applications and internal paperwork get signed. It does not add a cryptographic digital certificate. If a counterparty requires certificate-based signing with identity verification (common in government procurement), you will need a qualified signature provider; for everything else an image signature accepted by both sides does the job. More detail on legal standing is in the FAQ below.
Signing something confidential? After downloading, put a password on the file with Protect PDF before emailing it, and keep your own copy in the vault so the signed version is findable a year from now.
