No printer, no scanner, no DocuSign account. Here is how to draw your signature, drop it on the right page of a PDF, and download the signed file — all privately in your browser.

Sign it, don't print it
Signing a PDF used to mean a small ordeal: print the page, sign it with a pen, scan it back in (or photograph it), and hope the result is straight and legible. If you do not own a printer, it meant finding one. All of that to add a few strokes of ink to a document that started — and ended — as a file.
You can skip the whole round trip. An electronic signature lets you draw your name once and drop it directly onto the right page of the PDF, keeping the document crisp and digital from start to finish. No printer, no scanner, no third-party account.
Electronic signature vs digital signature
These two terms get mixed up constantly, and the difference matters when you are searching for the right tool.
- Electronic signature — the visible mark you draw and place on the page. It represents your intent to sign, the same way a handwritten signature on paper does. This is what most people mean by "signing a PDF," and it is what the E-Sign PDF tool creates.
- Digital signature — a certificate-based (PKI) mechanism that cryptographically binds your identity to the file and can detect whether the document was altered afterward. It is used for high-assurance workflows and requires a signing certificate.
For everyday agreements — contracts, NDAs, consent forms, HR paperwork, school and rental forms — a drawn electronic signature is the standard, accepted approach.
Three steps to a signed PDF
- Open the document. Drop your PDF into the E-Sign PDF tool. It opens and renders locally, so even before you sign, the file has not been uploaded anywhere.
- Draw and place your signature. Sign in the signature pad with your mouse, finger, or stylus — the pad captures smooth strokes for a natural look. Pick the target page from the thumbnail list (the last page of a contract, a specific form field, or initials wherever they are needed) and drop the signature into position. Use the width slider to scale it: wider for a prominent signature line, narrower for a tight form field. The aspect ratio is preserved, so your handwriting never looks stretched.
- Download. Save the signed PDF. The signature is added as a lossless vector overlay — the underlying text and images stay pixel-perfect, and only the page you signed gains the mark.
The whole thing takes under a minute, with no registration and no email verification.
Signing on a phone or tablet
Touch input is where drawing a signature actually feels natural. On a phone or tablet you can sign with your finger or a stylus, and because the pad captures smooth strokes, the result looks like your real handwriting rather than a jagged scrawl. After drawing, you place and resize the signature exactly as you would on a desktop. This makes it easy to sign something on the move — a form that lands in your inbox while you are away from your computer, for instance.
Why sign in your browser
The documents you sign are often the most sensitive ones you handle: an employment contract with your salary, an NDA, a lease, a medical consent form. These are exactly the files you should not hand to a random "sign your PDF here" website that uploads them to a server you know nothing about.
A browser-based tool keeps the whole process on your device. The PDF is rendered with pdfjs-dist, your signature is captured in a signature pad, and the two are combined with pdf-lib — all running as WebAssembly inside the page. Nothing is uploaded, nothing is stored on a server, and it keeps working offline once the page has loaded. The same privacy logic applies to the rest of your document workflow, from compressing a PDF to filling in a form: if the file never leaves your machine, there is nothing to leak.
Quick checklist
- Drop the PDF into the tool — it opens locally, no upload.
- Draw your signature with a mouse, finger, or stylus.
- Choose the right page from the thumbnails before placing.
- Use the width slider to fit the signature to the line, keeping its aspect ratio.
- Download the signed file — the original stays pixel-perfect, and everything happened on your device.
Quick steps
- 1Open the E-Sign PDF tool and drop your document in. Nothing uploads — the PDF is opened and rendered locally in your browser.
- 2Draw your signature with the mouse, your finger, or a stylus. Pick the target page from the thumbnail list, drop the signature where it belongs, and use the width slider to scale it to fit the line.
- 3Download the signed PDF. Your signature is added as a lossless overlay, so the original text and images stay pixel-perfect — and the file never leaves your device.
Frequently asked questions
In most jurisdictions an electronic signature you apply yourself — drawing your name and placing it on the document — is legally recognized for the majority of everyday agreements, the same way a signed-and-scanned page is. Some specific documents (certain deeds, wills, or notarized forms) have extra requirements, so check the rules for your document type. This is general information, not legal advice.
An electronic signature is the visible mark you draw and place on the page — that is what this tool creates. A digital signature is a separate, certificate-based (PKI) mechanism that cryptographically binds an identity to the file and can detect later tampering. For everyday contracts, NDAs, and forms, a drawn electronic signature is what people mean by "signing a PDF."
Yes. The signature pad works with touch, so you can sign with your finger or a stylus on a phone or tablet, then place and scale the signature exactly as you would on a desktop with a mouse.
No. The PDF is rendered with pdfjs-dist and the signature is embedded with pdf-lib, both running as WebAssembly inside your browser. The document and your signature are never sent to a server, so a sensitive contract or HR form stays on your device.
