Create a signature and sign a PDF online

Draw or type: which method?

Both methods give you a background-free PNG you can paste into Word, an email, or a PDF.

The image is cropped automatically around the strokes, leaving a 10-pixel margin.

Placing the signature on a PDF

The tool shows the page you select. Your click sets the center of the signature, and the slider makes it larger or smaller. The position is converted to PDF coordinates, including for rotated pages.

\[ \text{signature height} = \dfrac{\text{width}}{\dfrac{\text{PNG width}}{\text{PNG height}}} \]

• Suggested width: about 22% of the page width, between 80 and 220 points (1.1 to 3.1 in).
• The all-pages box is handy for initialing every page of a contract in the same spot.
• The document's text stays intact: the signature is added on top as an image.

How much is a signature image worth?

Under the US ESIGN Act and UETA, an electronic signature can't be denied legal effect just because it is electronic, as long as the signer intended to sign and consented to do business electronically. An image signature suits a letter, an estimate, a permission slip, or an internal form. For documents that require notarization or a certificate-based digital signature, such as some real estate or court filings, use a dedicated signing service.

How to sign a PDF online in five steps

You can sign a PDF without printing it. The whole job takes about a minute.

1. First, pick a method: draw or type.
2. Then draw your signature, or type your name and choose a style.
3. Next, drop in your PDF and open the page you need to sign.
4. Click where the signature goes and set the size with the slider.
5. Finally, download the signed file.

So your original document stays intact. The signature goes on top like a stamp. When you sign a PDF here, the file stays on your device.

Which kind of signature fits which document?

US law treats electronic signatures broadly, but the document decides how much proof you need.

This tool covers the first row. If a form needs a certificate or a notary, use a dedicated signing service instead.

Tips to sign a PDF cleanly

A few settings make your signature look sharper on the page.

• Draw it large, then shrink it with the slider. That way the strokes stay smooth.
• On a phone, use a stylus if you have one. Otherwise, use your finger.
• Aim for about 22% of the page width, which is 80 to 220 points.
• To initial a contract, check the box that signs every page.

Before you sign, you can combine files with Merge PDF, or keep only the right page with Split PDF. After you sign, lock the file with Protect PDF. If all you have is a photo of the form, turn it into a document first with JPG to PDF.

Check your signed PDF before you send it

A thirty-second review saves a resend. Run through these points.

• First, check that the signature lands on the right line.
• Then confirm it does not cover any text.
• If it looks too big, shrink it with the slider and place it again.
• If it looks blurry, draw it larger in the pad.
• When the contract has many pages, check the initials on each one.
• After you download the file, open it in your PDF viewer.
• Finally, name the file with the date, such as estimate-signed-10-30-2026.pdf.

The other person then gets a clean document. Also, you keep a tidy copy for your records. The PDF never leaves your browser, so you can sign a private document safely. If you doubt what the paper needs, ask the recipient which kind of signature they require.

Phone and two-signer cases

You can sign a PDF on a phone just as easily. The pad reacts to touch, so a finger works fine. Then the same steps apply. If two people must sign, one person signs first and saves the file. Next, the second person opens that file and signs a PDF that already carries the first mark. Each person uses a separate signature image. Because the tool never keeps your file, you save the result each time. So name each version clearly. When you need to sign a PDF again after a typo, start from the original. That keeps the page clean.

Small habits that save time

Small habits help too. Keep one signature image in your downloads folder. Then you reuse it for every form. Test the result on a dark background if you plan to use the PNG in a slide. The transparent PNG blends in. Print a copy only when the recipient insists. Otherwise, send the PDF as it is. Most offices accept it. Also, avoid scanning a printed copy. A scan lowers quality and adds noise. Save the signed file in two places. Then a lost email never costs you the original. Rename the file before you send it. Check the page count one last time. Remember that you control the final file. Nobody else sees it. You decide when it goes out.
