Signature for PDF
Create a signature for your PDF documents free — type your name, pick a clean style, and download a transparent PNG or SVG to drop into contracts and forms. No account.
What a “signature for PDF” really means
Most people searching for a signature for PDF want one of two things: a picture of their signature to drop into a PDF, or a way to e-sign a document. Signaturegen does the first — it generates a clean signature image (SVG or PNG) that you place into your PDF using the reader you already have. It is not an e-signing platform with audit trails; it makes the signature, and you add it where you need it.
That distinction is what keeps it fast and free: type your name, pick a style, download a transparent-background PNG, and your signature is ready to sit on any contract, form, or agreement — no account, commercial use included.
How to add a signature to a PDF
Create the signature here, then add it with whatever tool you already use. The transparent PNG is the easiest option because it layers cleanly over the page.
In Adobe Acrobat or Acrobat Reader
Open the PDF and choose Tools → Fill & Sign, or use Comment → Add Image, then place the downloaded PNG where the signature goes and resize it to fit the line.
On a Mac with Preview
Open the PDF in Preview and show the Markup toolbar. Use the image insert option to drop in your PNG, then drag it over the signature field and scale it to size.
In Google Drive or Google Docs
Open the document in Google Docs, insert the PNG with Insert → Image, position it over the signature line, then download or export the result back to PDF.
Create your PDF signature in three steps
1. Enter your name or initials
Type the name you sign with. Initials work well for forms with tight signature boxes.
2. Choose a clean, readable style
Pick from 26 styles. For contracts and forms, a clean, legible script reads better than an ornate one. Set the ink color to black or blue.
3. Download a transparent PNG (or SVG)
Download the PNG with its transparent background so it layers neatly onto the page, or grab the SVG if you need it razor-sharp at large sizes.
PNG or SVG for a PDF signature?
Both are free; the PNG is the usual winner for PDFs.
- PNG (transparent background): drops straight onto a PDF page with nothing behind it — the easiest, most reliable choice for most documents.
- SVG (vector): use it when you need the signature crisp at large sizes or for print-quality output.
Where a PDF signature comes in handy
- Contracts and agreements that arrive as a PDF to sign and send back.
- Business forms, approvals, and internal sign-offs.
- Freelance and client paperwork — proposals, invoices, statements of work.
- Applications and onboarding documents for school, internships, or a new role.
Is signing a PDF this way legally valid?
Adding a signature image to a PDF can be legally binding in many situations. Electronic signatures are recognized under the U.S. ESIGN Act and UETA, and under the EU's eIDAS regulation, when the signature reflects clear intent to sign and is applied with consent.
Some documents — certain notarized agreements, property transfers, or wills — require more than a signature image. Signaturegen produces the signature; it does not provide identity verification, audit trails, or notarization. For high-stakes contracts, use a dedicated e-signing service or confirm the requirements for your document.
Free, private, no account
Generating a signature for your PDF is free and needs no sign-up. Live previews render on demand and aren't saved, and commercial use is allowed. Paid plans (Standard $9.90/year, Premium $19.90/year) add a private signature library, premium styles, and higher-resolution exports if you sign documents often.
