Sign PDF

What Is Sign PDF?

Signing a PDF means putting your signature on a document so others know you agree or that you have seen it—like signing a paper form, but on your computer or phone. You might need to sign a contract, a permission slip, a bank form, or a school document. Instead of printing, signing with a pen, and scanning back, you can sign right on the screen. Our Sign PDF tool lets you open your PDF, create your signature once, and place it wherever you want. It is fast, free, and your file never leaves your device.

Where Do People Use PDF Signing?

People use PDF signing in many everyday situations. At work, you might sign an offer letter, an NDA, or an approval form. At school, parents sign permission slips or consent forms. At home, you might sign an insurance form, a rental agreement, or a government form. Banks and hospitals often ask for a signed PDF. Freelancers and small businesses use it to sign quotes and invoices. In short, whenever someone sends you a PDF and says “please sign and return,” you can use our tool to add your signature and send it back—no printer or scanner needed.

Different Types of Signatures (And When to Use Them)

Not every document needs the same kind of sign. Knowing the types helps you choose the right one and look professional. Here are the most common:

Full signature

Your full name, written or typed in a signature style. Use this for contracts, agreements, consent forms, and any document where you are legally or formally agreeing. It is the one people expect at the end of a letter or on the “signature” line. Our tool lets you draw it, type it in a cursive font, or upload a photo of your real signature—pick what feels most like you.

Initials

Short for “initial signature”—usually the first letters of your first and last name (e.g. “J. S.” or “JS”). People use initials to approve each page of a long document, to acknowledge a change on a single page, or on forms that say “initial here.” You can create initials the same way: draw them, type them, or use a small image. Place them in every spot the form asks for.

Date next to signature

Many forms want the date you signed. You can add the date as typed text (e.g. in the Type tab, type the date and place it next to your signature). Some documents have a separate “Date” line—place your signature on the signature line and your date on the date line so the document looks complete and correct.

Witness or second signer

Sometimes a document needs two people to sign: you and a witness, or you and another party. Create one signature (yours), place it, then create or upload the second person’s signature and place it in the right box or line. You can use different styles for each—for example, draw yours and type the witness name—so it is clear who signed where.

Company or authority stamp style

For official or business use, some people add a formal look: a typed name with a title (e.g. “John Smith, Director”) or a simple “Approved” with initials. Use the Type tab to type the exact text, pick a clear font, and place it where the form asks for approval or authority. It keeps the document tidy and professional.

Quick tip: If you want it to look like real pen-on-paper, use Draw or an uploaded image. If you want it neat and readable every time, use Type. You can even mix: full signature at the end, initials on each page.

How Do You Use This Tool?

First, you bring your PDF into the tool. You can drag the file and drop it on the big upload area, or click there and choose the file from your computer or phone. The tool then shows your PDF on the screen. Next, you create your signature. You have three simple options: draw it with your mouse or finger, type your name and pick a nice style, or upload a photo of your real signature. Once your signature looks good, you click “Place on PDF” and then click the exact spot on the page where you want it. You can move it by dragging and make it bigger or smaller using the corner handles. If your document has many pages, you can put the same signature on all of them at once, or put different signatures on different pages. When you are done, you click “Download Signed PDF” and get your signed file—ready to send.

Features Explained (The Small Details)

Uploading Your PDF

The upload area is the first thing you see. You can drag a PDF from your folder and drop it there, or click and pick the file. The tool supports all normal PDF files. While the file is loading, you will see a short progress message. Your PDF is never sent to our servers—it stays in your browser. That means your document stays private.

Creating Your Signature – Draw

If you choose “Draw,” you get a small canvas where you can write your signature with the mouse or your finger on a phone. You can pick an ink style: Classic, Ballpoint, Fountain Pen, Marker, or Brush. Each one looks a bit different, like different pens. You can also choose a color: black, blue, green, burgundy, or any custom color. There is a clear button to start over if you do not like how it looks.

Creating Your Signature – Type

If you prefer typing, click the “Type” tab. You type your name and the tool shows it in a nice cursive (handwriting-style) font. You can try different font styles until one matches how you want your signature to look. This is useful if you want a clean, readable signature without drawing.

Creating Your Signature – Image

If you already have a photo or image of your real signature (for example, from a white paper you signed and photographed), you can upload it. Click “Image,” then choose the file. The tool will use it as your signature. You can remove it and upload a different one if needed.

Placing the Signature on the PDF

Click the orange “Place on PDF” button, then click on the PDF where you want the signature. A copy appears there. Drag it to move it; use the small corner handles to resize it. The signature keeps its shape and does not get stretched. You can place more than one signature on different pages. The duplicate option lets you put the same signature in another spot without creating it again. With “All pages,” the signature appears on every page; you can still change the position on one page later without affecting the rest.

Moving Between Pages

Your PDF might have many pages. Below the PDF you will see “Prev” and “Next” buttons to go to the previous or next page. You will also see “Page X of Y.” The current page number is in a small box—you can click it, type a number, and press Enter to jump straight to that page. That way you do not have to click Next many times in long documents.

Downloading and Clearing

When you are happy with where all the signatures are, click “Download Signed PDF.” The tool builds the final PDF in your browser and downloads it. You can then send that file by email or upload it wherever it is needed. If you want to start over with a different PDF or change something, use “Clear PDF” to load a new file. Your signatures and placements are cleared so you can begin again.
