Solution 1Recommended

Use Adobe Acrobat Reader for Commenting and Highlighting

Since Adobe Export PDF is exclusively a conversion service, you need a dedicated PDF viewer like Adobe Acrobat Reader to annotate your documents.

Adobe Export PDF is a cloud-based service meant only for converting PDFs to Word, Excel, or RTF formats. It does not unlock or provide PDF editing or annotation features. To add highlights and comments, you must open the document in a supported PDF reader.

1
Download and Install Acrobat Reader

Download the free Adobe Acrobat Reader application from the official Adobe website and install it on your computer.

2
Open the PDF File

Launch Adobe Acrobat Reader, click 'File' in the top menu, select 'Open', and choose the PDF document you wish to annotate.

3
Access the Comment Tools

Click on 'Tools' in the top menu bar and select 'Comment'. A secondary toolbar will appear with options to highlight text, add sticky notes, and draw shapes.

Frequently Asked Questions

Does Adobe Export PDF include any text editing features?

No, Adobe Export PDF is strictly a document conversion service used to turn PDFs into editable Word, Excel, or RTF files. It does not include built-in PDF editing, highlighting, or commenting capabilities.

How can I add highlights to a PDF for free?

You can use free PDF software like WPS Office or Adobe Acrobat Reader. Simply open your PDF in these applications, navigate to the Comment or Annotation tab on the top menu, and select the Highlight tool.

Why are my PDF commenting tools grayed out in Acrobat Reader?

Commenting tools may be grayed out if the PDF document has security restrictions applied by the author that prevent annotations, or if the document is being opened in a limited browser-based viewer instead of the desktop application.
