Why and When Are Annotations in a PDF File Useful?

If you’re here, you probably desperately need to know how to annotate your PDF file. And who can blame you? At first glance, it seems like a PDF file can really never be edited, which can be a frustrating thing to learn.

But before we get into all of that, let’s get a little bit of perspective. The PDF format was a blessing bestowed upon us by Adobe back in the early 1990s. Its original purpose was to replace large document files since they can be very problematic when document sharing. Back then, it was even more challenging than it can be today since the computing power was minimal at best.

So yes, PDF seemed like the perfect alternative to huge files that were not even portable. Moreover, PDFs were quite impactful since they were one of the first file formats to combine all the major graphic design elements in one document. That too, WHILE keeping the document size as small as possible. As a result, the people back then were completely blown away by this beautiful innovation. 

Fast-forward to now – PDFs don’t seem that magical anymore. I mean, with all the new technological miracles we see every day, the fact that a file can do all that stuff is not very surprising. 

Yet, PDF remains popular and is actually quite beloved for users. The reasons for this are vast and varied, but one of the most critical things PDF offers is portable. Regardless of what computer system you are using, you can use a PDF, keep it on your storage, and even share it around. 

Here are a few common scenarios where digital PDF annotation tools are utilized to their fullest capacity:

Design and Artwork annotation

Adobe CC is the one-stop solution for all creative work for most designers. Opt to export their designs in PDF to share for review. PDF files ensure high image quality while making them easily accessible across most devices.

Catalog review and annotation

Digital catalogs often contain many images and text. All put across multiple pages in a PDF. Annotation tools are a must if you need to make any sense from feedback.

Magazine review and annotation

Magazines, both digital and print, undergo several critical review stages and often deal with 100s of PDF pages. Imagine having to print, annotate, scan and send every single time! Online annotation tools will be a lifesaver.

Website wireframe annotation

Online review and marking tools help the marketing people to polish their emails and cut through the noise to communicate the right message and approvals on any design or content-related changes from key decision-makers.

Digital Proposals proofing

A proposal not communicated well can make or break a business. Teams typically use these tools to take approvals from senior-level stakeholders while aligning their designs with the business vision.

Print file annotation

Don’t waste pages for draft printouts, seriously! PDF annotation tool helps to consolidate the feedback from different members and clients and drive the print towards its final form.

Digital Ad proofing

Digital proofing tools help ad makers and marketing professionals review and work on minute details of their print and digital ads until they are sure about their campaigns’ performance.

How to Annotate a PDF: Important Features of PDF Annotation Software

But, how to pick the best software solution for PDF annotations?

The one thing that you must understand is that PDFs are fixed documents. What this essentially means is that they cannot be edited entirely. If you’re planning to edit the WHOLE content of your PDF document, let me tell you straight up that it’s not possible. 

What you can do instead is make annotations to your document. The annotations will make sure that your point of view, along with the original content, is visible to whoever has access to your PDF. In short, annotation is a cheat code that lets you make edits without making edits. 

When choosing software, these are the things that you need to ensure that your annotation tool has:

  1. A highlight section.
  2. Strikethrough function.
  3. Copy text function. 
  4. Ability to add hand drawings and shapes. 

While there are some advanced tools out there that will offer you way more than this, these four features are absolute essentials when it comes to annotation software. If your software has these, rest assured that your annotation experience will be seamless, and you can actually make alterations to your PDF whenever and however you like.

Mark up Pdf files with ease and without restrictions.
