Annotating a PDF is the best way to share feedback and ideas, and collaborate with friends and co-workers.
But if you’re struggling to annotate PDFs effectively because the process is complicated, we’ve got you covered.
In this article, we’ll break down how to annotate on PDFs online and offline. Here’s what’s covered:
But before we delve into the specifics, let’s look at what a PDF annotation is.
Annotation is a fancy way to say you’re adding notes or highlighting important points in a PDF document.
You can do it for your reference or use it to break down important information for your readers. Here are a few ways you can annotate your PDF document:
In short, you’d add digital highlights and drawings to your eBook or PDF document instead of running a highlighter, writing in the margins, and creating rough sketches.
Adding markups to a document when you’re reading it helps you comprehend the information you’re consuming and keep track of it seamlessly.
It’ll ensure you won’t read five pages and realize you lost track of what the author said three pages ago.
Instead, you’ll read actively and comprehend information easily as annotations help you connect ideas and visualize concepts quickly.
But remember that annotations are effective only when done sparingly. So, ensure you highlight only the important points, not the whole document.
Next, let’s look at a few ways to annotate PDFs easily.
Adobe Acrobat is everyone’s go-to software to annotate PDFs easily. Since it works well on Windows (and Mac), chances are you already have it installed on your system.
And regardless of whichever operating system you use, Adobe Acrobat offers the following annotation features:
Before we look at how to access all of these features in detail, let’s look at how you can access the tools.
First, you’ll need to make the markups and annotations toolbar visible. So, go to “Tools” and select “Comment” to open the toolbar.
The toolbar has all the features, and if you want clarity on what each one does, all you’ve got to do is right-click the toolbar and click “Show all Labels.” This will display the tool’s name alongside its icon to avoid confusion.
Annotations can include both text and drawing annotations
Text annotations include:
All you’ve got to do to access these features is to simply drag your cursor through the required text and select the required tools as shown below:
You can manually draw an image and erase it or use Acrobat’s toolbox to draw various shapes with drawing annotations.
To draw an image manually, use “Draw” and “Erase Drawing” from the toolbar. And if you want to add shapes to your PDF, click the three dots next to Erase Drawing and choose a shape.
To add sticky notes to your PDF, you should enable the comments feature first. Once you’ve done that, click the first tool on your toolbar to add your sticky note.
If you’d like to resize the pop-up box, right-click on the note, select “Open Pop-up note,” and resize the box according to your preference.
You can also change the text formatting within the sticky note and its color. To do this, simply click the three-dots symbol on the toolbar and perform the actions as shown below.
Here are a few different ways to save your annotations on Adobe Acrobat.
If you’re using Adobe Acrobat Reader instead of Adobe Acrobat, choose File > Save As or File > Save As Other > Text.
The only caveat with using Adobe Acrobat is that it's a paid tool, and you’ve got to spend about $14.99 each month to keep using all its features.
For free PDF annotators that have the same functionality check out Kdan’s free PDF reader on Microsoft’s online store.
Now that we’ve looked at a free Adobe alternative for Windows let’s look at one for Mac in the next section.
If you’re a Mac user, you can use Apple’s native app, Preview, to annotate your PDFs and collaborate with your team. But before you start adding your annotations, click the Show Markup toolbar button to make your toolbar visible.
Similar to Adobe, Preview also offers tools to create image and text annotations on your PDF. We’ve listed some of the tools below.
Now that we’ve looked at how to annotate PDFs offline on your computer let’s look at how you can do the same for an online document.
Preview automatically saves changes made to the PDF. But you can also click File>Save to save your PDF file.
If you want to collaborate with your team online and share feedback, Google Drive is the best option, and there are two ways to annotate a PDF using this tool.
Annotating a document on Google Sheets is pretty straightforward. All you’ve got to do is click the “+” icon to start adding comments.
But before that, you’ll need to click the PDF and choose “Google Sheets” from the “Open With” option.
Once that’s done, you can start adding comments to the document as you would normally do.
The biggest downside of employing this method is that it's hard to see white or light-colored text, and you've got to convert the document into a PDF and upload it, so your team views the feedback.
Apart from being cumbersome, this process also makes version control difficult, which brings us to the second method.
Lumin is a third-party integration and a cloud-based PDF annotator which allows users to edit PDFs from any device.
To start annotating PDFs on Lumin, click the PDF on your Google Drive and choose Lumin from the “Open With” option.
To open the editor, grant access to your Google Drive and choose the account containing the PDF if you’re using multiple Google accounts. Once the editor opens, you can annotate on the PDF as follows:
Annotating PDFs helps highlight important points or share feedback.
There are different ways to annotate PDFs depending on your operating system.
You can use Adobe Acrobat or Microsoft's free apps from the online store if you're a Windows user.
But if you're a Mac user, you don't have to worry about using paid apps as it has a native PDF annotation tool called Preview.
If you're annotating PDFs online for collaboration, you can always use Google Sheets or a third-party integration like Lumin to get the job done.
