Advanced Features

If you are someone who frequently signs documents and wants to make the signing process faster, then the “Manage Signatures” feature is for you. By using it, you can save your signature and give it a unique name for easy access. This way, when you have to sign a document in the future, you can select it from a saved list of signatures and insert it with a single click.

To access “Manage Signatures,” you simply need to click on the “Signature” icon located in the “Markup Toolbar.” Once you’ve done that, click on the “Add or Remove Signature” option. The “Manage Signatures” menu will popup, where you can create new signatures, delete existing ones, and rename them if needed.

To add a new signature, click on the “+” sign located at the bottom of the screen. You can then create a signature using the following options: typing, drawing, or using an image. If you choose to type your signature, you can select the font, size, and color that you want to use. If you choose to draw your signature, you can use your mouse, trackpad, or a stylus to create it. Finally, if you choose to use an image, you can upload one from your computer, phone, or tablet.

Once you’ve created your signature, you can give it a unique name and save it for future use. Whenever you need to use it, click on the “Signature” icon and select it from the saved signatures.

Aside from the “Manage Signatures” feature, there is also the “Markup Toolbar” which offers additional annotations and comments that you can add to the PDF. These can be helpful if you need to provide feedback or additional information to the recipient of the document.

The “Markup Toolbar” features include text highlighting, underlining, and strikethroughs. You can also add text boxes, shapes, and arrows to the PDF. Additionally, there’s a feature where you can add your signature directly to the document using the “Signature” icon. Just click on it, select your saved signature, and drop it into the document where you need it.

As you can see, the “Manage Signatures” and “Markup Toolbar” are valuable tools to have when signing and annotating PDFs. By taking advantage of these features, you can save time and provide additional information that will help ensure that your documents are accurate and complete.

  • Preview: It’s the default PDF viewer on Mac, and it comes with a built-in signature tool. Preview allows you to sign a blank piece of white paper with a black pen and save it as a signature for future use. You can also add text boxes, shapes, and annotations to your PDF.

Preparing Your Signature

Before you sign a PDF electronically, you need to create a signature that looks professional and consistent across different documents. Here are some tips to prepare your signature:

  • Choose a handwriting font: If you don’t have a digital signature or don’t want to draw it by hand, you can use a handwriting font that mimics your handwriting. You can find many free handwriting fonts online or purchase a premium one.
  • Practice your signature: Whether you’re using a real signature or a font, practice signing your name several times until you’re comfortable with the style, size, and pressure. You can also sign a blank piece of paper and scan it to make a digital copy.
  • Save your signature: Once you have a signature you’re happy with, save it in a secure location on your computer or in the cloud. You may want to use different signatures for different purposes, such as a personal one for casual documents and a business one for professional documents.

By taking the time to create a good signature, you show professionalism, attention to detail, and reliability to your clients and partners.
