Can't Highlight Text in PDF: Easiest Solution For You!

Part 1. Why Can't I Highlight Text in PDF?

Wondering why can’t I highlight text in PDF? Well, this can occur due to different causes. Below, we’re providing some of the reasons why you’re unable to highlight text in PDF –

• PDF Security Settings:Sometimes, PDF files are protected with security settings that prevent certain actions like highlighting, copying, or editing text. These settings are often put in place by the creator of the PDF to control how the document is used.
• Scanned Documents:If the PDF is a scanned document, rather than a text-based PDF, you can’t highlight text in PDF because there's no actual text to select. Scanned documents need to be converted using Optical Character Recognition (OCR) to make the text selectable.
• PDF Viewer Limitations:Some PDF viewers or applications may have limitations or bugs that prevent certain features like highlighting from working properly. In such cases, trying a different PDF viewer or updating your current one might help resolve the issue.
• Software Bugs or Compatibility Issues: Occasionally, bugs or compatibility issues with your PDF reader software can prevent highlighting. Updating your software to the latest version or using a different PDF reader might solve the problem.
• Document Permissions and Author Settings:The author of the PDF may have restricted certain actions, including highlighting, through the document's permissions settings. This is often done to protect the content of the document from being altered or copied without authorization.
• Document is Corrupted:Occasionally, if a PDF file is corrupted or damaged, it can affect the functionality of features like highlighting. In such situations, you have to repair or redownload the PDF file and resolve the issue.

Part 2. How to Highlight Text in PDF?

If you’re not able to highlight in PDF, there are several solutions you can try depending on the cause of the problem –

• Check PDF Security Settings

If the PDF is protected by security settings, you might need to change those settings to enable highlighting. If you have the password or permission from the document’s creator, you can remove or adjust these restrictions using a PDF editor. This will allow you to perform actions like highlighting, copying, or editing the text within the document.

• Use Optical Character Recognition (OCR)

For scanned documents, highlighting text isn’t possible because the document is essentially an image rather than text. To convert the image into selectable text, you need to use OCR software. Many PDF editors, like Afirstsoft PDF or online tools, offer OCR functionality. Once you run OCR on the scanned PDF, it will recognize the text, making it possible to highlight, copy, or edit it as needed.

• Try a Different PDF Viewer

Sometimes, the issue lies with the PDF viewer you are using. Not all PDF viewers have the same features or may have bugs that prevent certain functionalities. Switching to a different PDF viewer, such as Afirstsoft PDF, Adobe Acrobat Reader, or other reputable PDF applications, might resolve the issue. Additionally, ensuring that your current PDF viewer is updated to the latest version can fix bugs and improve functionality.

• Update or Change Your Software

If the problem is due to software bugs or compatibility issues, updating your PDF reader to the latest version might solve the problem. Software updates often include bug fixes and improvements that enhance functionality. If updating doesn’t help, consider using a different PDF reader that is known for robust features and compatibility, like Afirstsoft PDF, Adobe Acrobat Reader, or Sumatra PDF.

• Check Document Permissions and Author Settings

The author of the PDF might have set permissions to prevent highlighting or other actions. If you have permission to edit the document, you can change these settings using a PDF editor. Open the document in a PDF editor, go to the document’s properties, and modify the security settings to allow highlighting. If you don’t have the necessary permissions, you may need to contact the document’s creator for access.

• Repair or Re-download the PDF

If the PDF file is corrupted, it might affect your ability to highlight text. Try opening the document in a different viewer to see if the problem persists. If it does, you can try repairing the PDF using specialized software or online tools designed to fix corrupt PDF files. Alternatively, re-downloading the PDF from its source might resolve the issue if the file was damaged during the initial download.
