- Product
- Adobe Export PDF
- Device & OS
- not provided
- Scenario
- Attempting to annotate, highlight text, or add comments directly to a PDF document.
- Observed behavior
- The commenting, highlighting, and annotation tools are completely missing or inaccessible within the Adobe Export PDF service.
Verify whether you are viewing your document in a web browser or a dedicated PDF application, as feature availability heavily depends on the specific software you have open.
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.
Download the free Adobe Acrobat Reader application from the official Adobe website and install it on your computer.
Launch Adobe Acrobat Reader, click 'File' in the top menu, select 'Open', and choose the PDF document you wish to annotate.
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.

Upgrade to Adobe Acrobat Pro for Advanced Editing
If you need to edit the actual text and images in addition to basic commenting, a full PDF editor is required.
Easily Highlight and Comment on PDFs with WPS Office
Stop struggling with limited conversion tools. WPS Office features a comprehensive built-in PDF editor that lets you easily highlight text, add comments, insert shapes, and convert files—all in one lightweight, free application.
- 1. Open your PDF in WPS Office: Launch WPS Office and drag and drop your PDF file into the workspace, or go to 'Open' on the home screen and select your document.
- 2. Access the Comment Tab: On the top navigation ribbon, click the 'Comment' tab to reveal a full suite of PDF annotation tools.
- 3. Highlight and Annotate: Select the 'Highlight' tool to mark important text, or choose the 'Note' icon to drop text comments anywhere on the PDF page.
- 4. Save or Export your File: Once your annotations are complete, click 'Menu' > 'Save' to keep your changes, or use the 'PDF to Word' tool if you need to convert the document.

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.
