    After creating a document, converting it into Adobe Acrobat Reader is usually very easy for storage in my computer, sending/sharing via emails, etc. This also saves a significant amount of unnecessary printing and paper waste, which is great for reducing waste. I don't have to worry about not having the right software/app to view, edit, and share with anyone.

    Pros
    Adobe
    • It has all the tools that individuals need for reading/doing light editing of PDF files.
    • It is the most secure PDF reader on the market, and it tends to get patched with timely updates on a regular basis.
    • It usually works very well, as far as the software itself. It doesn't crash a lot, or is particularly an error prone software platform.

    Cons
    Adobe
    • Being able to add image "stamps" to a document is a little tricky as the stamp has to already be in PDF format (at least on Mac) to work. This mean you have to convert the image to PDF before you can use it as a stamp.
    • Being only able to save one signature and one set of initials is a bit of a pain but you can actually use stamps if you need different versions frequently used scribbles for various reasons. The stamp won't secure the document and prevent future changes the same way the signature would though.
    • All of the other features you might want to use are only included with Acrobat Pro but the options are all displayed in the Reader app. When clicked they will offer the free trial that leads to a paid subscription. This is more of an annoyance but you can't fault Adobe for trying to make a sale.

    To be honest, I do not have any say in the renewal of Adobe Acrobat Reader DC. It is managed at an enterprise level, and the decision to renew or not renew is handled well above my pay grade as an external consultant.

    Usability
    Adobe
    Again, Adobe Creative Suite is widely used and backed by an industry leader, making the experience very familiar and common for anyone who has used a PDF and wants more features to interact with it. It also makes copy text a lot easier than just previewing the file.

    We have reviewed DocuSign in comparison to [Adobe] Acrobat Reader [DC's] e-sign capabilities. We found that DocuSign has more robust options when creating contracts and consent capabilities. DocuSign's online UI is much more suited to this type of task as well. However, we decided to stick with [Adobe] Acrobat Reader DC because of the price (DocuSign is more expensive) and we felt we didn't need all of the bells and whistles for contract signature and consent.

One click switches to the Editor to fill, annotate, or redact the same document.Screenshot of Users draw a freehand signature, type one, or upload an image — then insert it into any PDF in one click.
