PDF Studio

Sign PDF

Add your signature to PDF documents. Draw, type, or upload your signature and place it anywhere on the page.

Free · No signup required

Printing a document just to sign and re-scan it is slower than it needs to be for most everyday paperwork. PDF Studio lets you create a signature by drawing, typing, or uploading an image, add your details, and stamps a signature block onto the document — turning a print-sign-scan routine into a few clicks.

How to Use Sign PDF

  1. 1

    Upload the PDF that needs a signature.

  2. 2

    Create your signature by drawing it, typing it in a cursive style, or uploading an image.

  3. 3

    Fill in your name and details, then apply — the signature block is added to the last page. Download your signed PDF.

Skip the print-sign-scan routine

Everyday paperwork — rental forms, permission slips, quotes, internal approvals — does not need a printer. Sign PDF lets you create a signature on screen and apply it to a PDF in a minute, so a document can be signed from a phone or laptop and returned the same day.

Three ways to create your signature

You can draw your signature with a mouse, trackpad, or finger on a touch screen; type your name and have it rendered in a signature style; or upload an image of your handwritten signature. You can also add initials and a company stamp image for documents that need them.

What gets added to the document

PDF Studio adds a signature block to the last page of your PDF, containing the signature image, your full name, and the date. You can fill in optional details — job title, department, company, email, phone, location — and choose a reason such as approved, verified, witnessed, notarized, or acknowledged, or write your own, plus a short note. Fill in only what the recipient needs.

The block is placed on the last page rather than at a spot you drag to, which suits most contracts and forms, where signatures go at the end. If a document needs a signature in the middle of a page, this tool is not the right fit.

Is it legally valid?

Whether an image-based electronic signature is accepted depends on the country and the kind of document. Many everyday agreements accept simple electronic signatures, while some — property transfers, certain legal filings — require a certified digital signature issued by a trusted authority. This tool applies a visible signature block; it does not create a cryptographic certificate-based signature. When in doubt, check with the person or organisation requesting the signature.

Signing happens in your browser, so the document and your signature are not uploaded.

Frequently Asked Questions

How do I sign a PDF online?

Upload your PDF to PDF Studio, create your signature by drawing, typing, or uploading one, add your details, and apply. The signed PDF downloads straight away.

Is a signature added this way legally binding?

Requirements vary by jurisdiction and document type — for anything requiring a certified digital signature, confirm what your specific use case legally requires.

Can I reuse the same signature on multiple documents?

Each session lets you create and place a signature as needed; save an image of your signature separately if you want to reuse it quickly.

Where does the signature appear on the document?

PDF Studio adds a signature block (signature, name, date, and any details you fill in) to the last page of the PDF. It does not currently let you drag the signature to a custom spot.

Where does the signature appear on the page?

In a signature block at the bottom of the last page. You cannot currently drag it to a custom position.

Can I add initials or a company stamp?

Yes. Alongside the signature you can add typed initials and upload a company stamp image, and they are included in the signature block.

Is this a certified digital signature?

No. It adds a visible electronic signature block. Documents that legally require a certificate-based digital signature need a dedicated signing service.

Is my document uploaded when I sign it?

No. Signing is done in your browser, so the PDF and your signature stay on your device.
