#2: Adobe Acrobat Reader DC

Reader DC is a free application from Adobe, the creator of the PDF format. Its premium cousins, Acrobat DC and Acrobat Pro DC are full-fledged editors, but with Reader DC, you can view and read PDFs, fill and sign forms, and even add comments and other annotations - including a highlight PDF tool. Reader DC is a mature product that's been on the market since 2015, and since it's free, it has a massive user base numbering in the millions.

However, Reader DC is not as capable as its more powerful PDF editing cousins and is quite limited in functionality if you're looking for a robust all-in-one PDF solution. Moreover, if you need more features, the switch to Acrobat DC or Acrobat Pro DC is pretty expensive. You can check the Adobe Acrobat alternative.

Pros

• Cross-platform availability - Win, Mac, iOS, Android

Cons

• Limited features
• Expensive to upgrade
• Bulky software - slows down older systems

#3: PDF Annotator

This PDF annotator for PC is an excellent tool if the only thing you need to do with your PDFs is to annotate them. It offers a good range of annotation tools such as highlighting, commenting, making notes, drawing freehand, adding photos, and so on. You can also fill and sign PDF forms, add blank pages between existing PDF pages, manipulate page positions, and even take advantage of the presentation mode when showing the PDF to others.

In addition, you get access to file conversion, PDF security, page numbering, page extraction, document splitting, and other features as well. The best thing about this PDF highlighter free download is that it supports the use of style on touch-enabled Windows devices such as convertibles and tablets.

Pros

• Extensive annotation tools
• Can add photos as annotations
• Stylus support

Cons

• Windows-exclusive application
• Limited feature set - no editing, etc.
• Expensive annotation tool

#4: Foxit PDF Reader with Highlighter

As a PDF reader app, Foxit's utility is pretty basic. You can draw, add comments, and share PDF files but you won't find other features such as text markups or stamps. However, it's great for document security because you can verify digital signatures, add a handwritten signature or add a legally valid electronic signature.

It also allows users to attach documents and other files to PDF, and it can be integrated with cloud storage accounts or CMS applications for team collaboration. Other than that, it's little more than a PDF viewer with a highlighter. Nevertheless, it is definitely among the top 10 PDF highlighter apps due to its widespread use in the Enterprise segment.

Pros

• Simple and intuitive UI
• Easy to deploy organization-wide

Cons

• No text markup option to highlight PDF text after the selection
• Limited functions in highlighting PDF
• No PDF editing
• No advanced features

---

#5: Drawboard PDF

This robust PDF highlighter tool offers a rich PDF annotation experience on a well-designed and organized interface that will appeal to the aesthetic design side of the user. You can add bookmarks to mark specific pages in a large PDF, insert objects such as shapes, lines, and arrows, and even draw directly on a PDF file. One of the best features is its collaborative ability, which allows users to work on a document in real time once it's been uploaded to the cloud.

It also supports writing or drawing with a stylus. Although this feature can be found in many other PDF highlighter tools, the unique aspect here is the pressure sensitivity, which means you can draw dark or light lines just by changing the pressure applied to the touch-enabled surface of the device.

Pros

• Pressure-sensitive ink
• Various annotation tools available
• Additional features such as flattening and optimizing PDF
• Work in real-time with cloud-uploaded PDFs

Cons

• The free version has limited features
• Cloud access is limited to 10 documents of 40MB each

#6: EaseUS PDF Editor

This is an advanced tool that's been around since 2004. The features are quite extensive so it's more than just a PDF highlighter. You can use it to create PDF forms, edit PDFs, and even convert them to and from more than 10 different file types. In addition, you can use the OCR function to convert non-editable or scanned PDF files into editable versions.

However, the downside is that there's only a free trial version, but you'll need to upgrade if you want access to all features on an unlimited basis. It also offers PDF signing, Bates Stamping, security, file merging/splitting, PDF compression, and watermarking.

Pros

• Good for fulfilling basic annotating needs
• Extensive feature set
• Advanced tools such as OCR

Cons

• Highlight PDF feature limited to commenting
• Only supports Windows
• The trial version is capped at 5 pages

It offers a full array of rich features such as file conversion, PDF editing, OCR, file merging and splitting, PDF form creation, PDF compression, and more. The application is not exactly cheap but is often available with discounts, and there are options to either subscribe monthly or yearly or purchase a one-time perpetual license that never expires.

Pros

#8: Preview on Mac - Free PDF Highlighter APP

The Mac Preview app is an excellent annotation tool for macOS users. Obviously, there's no PDF highlighter for PC version but it's a free tool that comes with your Mac so it's definitely something you should look into. Although the app is designed primarily for image viewing, it is a surprisingly capable application to highlight PDF as well. In fact, you can even export PDFs in other formats such as images using this versatile native Mac app.

The only problem here is that you can select text but not highlight it as you can with UPDF or other PDF highlighter applications for Mac. However, there are other markup tools such as strikethrough and underlining to highlight specific text content. You also have shapes, freehand drawing, and other features that make this a worthwhile app to consider as a free PDF highlighter.

Pros

• Free application
• Mac-native experience
• Versatile app for PDFs and images

Cons

• No text highlighting
• Limited PDF functionality
• No Windows version

Don't expect too much from this app in terms of extensive PDF tools because it only offers the basics - PDF annotations such as the PDF highlighter, page organization, form creation, etc. For advanced actions such as PDF editing, you'll be better off with UPDF, another free PDF highlighter app that also includes a PDF editor module.

Pros

• Convenient browser-based use
• Good selection of annotation tools

Cons

• Limited PDF features
• Outdated user interface

• Easy operations

Cons

• No PC version
