You can use Adobe Acrobat DC to fill and sign PDF documents. Here is a sample file you can download and try signing.

1. Open the document in Adobe Acrobat DC.
   • If Acrobat is not your default PDF application, right-click on your document, choose Open With, then Adobe Acrobat DC.
2. In right pane, click Fill & Sign.
3. In the top toolbar, you can use the tools to add text, place marks, and sign the document.
4. Place text and marks by clicking the toolbar button, and then clicking where you want to place it on the document.
5. When you sign the document, if this is your first time you'll have to add a signature.
   1. You may use a preformatted signature, or choose Draw at the top of the dialog.
   2. Using your tablet pen, draw your signature in the provided box.
      1. The signature preview will be somewhat low quality. Do not worry too much if some of your lighter pen strokes are not visible.
      2. If you do not like your signature, you can click “Clear Signature” and draw it again.
   3. Once you have drawn your signature, click “Accept” in the bottom right.
6. Your handwritten signature will now appear under your cursor. Move the signature to the location you would like to place it, then click once.
7. If the signature is too large or two small, you can resize it by clicking and dragging the square in the corner of the signature box.
   1. Save the document to store the filled information and your signature. After saving a signed document, you won't be able to edit the text anymore.

1. Click on Tools at the top-right of the Acrobat window.
2. Click on Add Text under Content Editing in the right pane.
3. Move the cursor to where you would like to add text. Generally, you want to place the bottom line of the cursor just a bit above where you want the bottom of your text to be. Click to start entering text.
   1. After you enter text, you may click again elsewhere to add more.
4. When you are done adding text, go to File > Save. When asked if you want to finalize the changes, click Confirm. Then save the document as you normally would.
