    • How to sign pdf electronically for free

    Let’s dive in.

    What Is Adobe Acrobat Reader?

    Adobe Acrobat Reader is a PDF document software that allows you to view and edit PDF files. It includes both free and paid versions, offering more features and functionality. You can use the free version to open and display PDF files. The paid version allows you to edit, add signatures, print, and alter PDF files.

    Adobe Acrobat Reader provides many benefits, such as opening all PDF files. This is important because PDFs can come in several types, but not all PDF readers can open and view each type. 

    The downside to Adobe Acrobat Reader is that you’ll need the paid version to edit PDF files. More specifically, the premium version — Acrobat Pro — allows you to annotate, scan, and convert. If you need to sign a PDF file and want to use Adobe, you’ll need to purchase the paid model.

    Why Would You Avoid Adobe Acrobat Reader for Signing PDFs?

    Adobe Acrobat Reader is a feature-rich, complete PDF reader, which isn’t surprising. Why? Adobe created the PDF file format, so Adobe Acrobat Reader was the first-ever PDF reader. Unsurprisingly, the original is so compatible, accessible, and complete.

    However, the popular software does have some drawbacks. Because the platform was — and still is — designed for larger enterprises, it’s less affordable for small and medium-sized businesses.

    Although a free version of Adobe Acrobat Reader exists, it can only open and view PDF files. If you need to sign a PDF document electronically, you won’t be able to do so with the free software. You’ll need to purchase the premium offering: Acrobat Pro.

    You don’t need to do this if you need to sign a PDF document digitally. Instead, there are several free alternatives available on the market. For example, you could use a digital signature software tool. These can be used to sign PDFs electronically and can also be used to sign other file types digitally.

    Here’s a walkthrough of how the app works for signing a PDF:

    1. Log in to your Signaturely account.
    Log in to signaturely

    To begin, log in to your Signaturely account from the main website. If you don’t have one yet, create one — it’s free to do so.

    1. Select the appropriate “Who needs to sign?” option.
    Select Signees

    After logging in, you’ll land on a page that presents three choices:

    • Only Me
    • Me & Others
    • Only Others

    If your PDF document only needs your digital signature, select “Only Me.” If you need your signature and somebody else’s, select “Me & Others.” If you only need someone else’s signature, select “Only Others.”

    1. Attach your PDF document and upload it.
    Upload PDF

    On the next page, you’ll be able to attach your PDF document. Scroll down and find the “File Uploader” section. Select “Upload File” and locate your PDF document. Once you’ve done that, hit the “Fill Out & Sign” button.

    1. Use the document editor to add your digital signature to the signature field.
    Prepare for signing

    The next page will be the document editor. This is where you can create and add your digital signature to your PDF document. You can also add text, check marks for checkboxes, and dates.

    After you review signature placement and add all elements to your PDF document, press “Send” in the top right corner. This will complete your document and allow you to email and download it.

    Preview and Markup on Mac

    If you’re a macOS user, another suitable solution for signing PDF files exists. There is a default application called “Markup” that you can use to open and view images and PDF files. Not only can you open and view PDFs with it, but you can also fill and sign them.

    This is a fantastic, simple solution for anyone using a MacBook, iPad, or iPhone. It’s also free because every device that runs the macOS operating system comes with the Preview app.

    Printing, Signing, and Scanning

    If electronic document signing is not suitable for your situation, you can always use the traditional printing, signing, and scanning methods. Many businesses still do this, even though it’s an outdated, inefficient way of dealing with contract and document workflows.

    Here’s a guide on how to sign a PDF without printing, in case you don’t have a printer.
