How to Remove Highlights from PDFs: Key Methods Explained

There are multiple ways to remove highlights in PDFs depending on what software or device you're using. We’ll break down the easiest and most reliable methods, so you can choose the one that works best for you.

Method 1: Use Adobe Acrobat (Desktop and Online)

Adobe Acrobat is one of the most reliable tools for editing PDFs, including removing highlights. Whether you’re using the desktop version or Adobe Acrobat online, both allow you to remove highlights quickly.

Here’s how to remove highlights in Adobe Acrobat:

1. Open the PDF file with Adobe Acrobat.
2. Click on the “Tools” tab at the top.
3. Select the “Comment” option.
4. Click on the highlighted text you want to remove.
5. Right-click and select "Delete" or simply hit the delete key on your keyboard.

With the online version of Adobe Acrobat, the steps are very similar. Just upload your document and follow the same steps to unhighlight in PDF.

Adobe Acrobat provides a professional solution, especially if you’re already using it for PDF management. It’s user-friendly, but for more advanced editing options, you may need the paid version.

Method 2: Use Online Tools for Windows/Mac (PDFgear, DocHub, Smallpdf)

If you don’t have Adobe Acrobat, no worries! There are plenty of free online tools to help you remove highlights in PDFs. Websites like PDFgear, DocHub, and Smallpdf are great alternatives, offering simple editing features right in your browser.

Here’s how to use online tools to remove highlights:

1. Visit an online PDF editor like PDFgear, DocHub, or Smallpdf.
2. Upload your PDF file to the platform.
3. Use the text selection tool to highlight the highlighted text.
4. Delete the highlights by either right-clicking and selecting “Delete” or hitting the delete key.

These online tools are free and easy to use, perfect for when you need a quick fix without installing any software. However, free versions may have limitations, so consider upgrading if you need more advanced features.

Method 3: Use Mac Preview (For Mac Users)

If you’re using a Mac, you don’t need to download any additional software to remove highlights from PDFs. The Preview app that comes with macOS is perfectly capable of handling basic PDF edits, including removing highlights.

Here’s how to remove highlights using Preview:

1. Open the PDF with Preview.
2. From the top menu, click on the "Tools" tab, then select “Annotate” and choose “Highlight”.
3. Find the highlighted section and right-click on it.
4. Click "Delete" to remove the highlight.

Preview is a simple and effective solution for Mac users who need to remove highlights without the need for extra tools.

Method 4: Remove All Highlights at Once

If you have a document full of highlighted text and want to remove all of them at once, some PDF editors allow you to do this in bulk. Adobe Acrobat, for instance, lets you remove all highlights in one go, saving you time.

Here’s how to remove all highlights at once using Adobe Acrobat:

1. Open the document in Adobe Acrobat.
2. Go to the “Tools” tab and select “Comment”.
3. Click on “Highlight” in the list of annotation tools.
4. Select all highlighted text, either by clicking or using the search function.
5. Press the “Delete” key to remove everything at once.

This method works well when you have a long document and don’t want to manually remove each highlight.

Method 5: Remove Highlights from PDFs Converted from Word

If your PDF was converted from a Word document and you want to remove highlights, you may face an additional challenge. In many cases, the highlights are part of the text formatting, which can be tricky to edit directly in a PDF.

Here’s how to handle highlights in PDFs converted from Word:

1. Open the PDF in your PDF editor.
2. Select the highlighted areas and check if they are annotations (usually represented with a box).
3. If they are annotations, simply delete them like any other comment.
4. If the highlights are embedded within the text, you may need to edit the original Word document to remove them, then convert it back to a PDF.

This method is a bit more involved, but it ensures that the highlights are fully removed from the document. If you find this process tricky, try converting the document back to Word and fixing the highlights there before converting it again to PDF.

When You Can’t Remove Highlights: Troubleshooting Tips

If you’re having trouble removing highlights, there may be a few reasons why it’s not working. Here’s a quick guide to some common issues and how to fix them.

• Issue 1: Highlight is part of the image. If your PDF is an image (like a scanned document), you can't remove highlights directly. You might need to use OCR (Optical Character Recognition) to extract text, then edit it.
• Issue 2: PDF is password-protected. If the PDF is locked, you won’t be able to edit it without the password. You can either contact the document creator or use an unlock tool to remove restrictions.
• Issue 3: Highlighting is part of the document’s structure. Sometimes, highlights are not annotations but part of the document’s actual text formatting. In such cases, you may need to go back to the source document (like a Word file), remove the highlights, and re-export the PDF.
• Issue 4: Free tools have limitations. Many free online tools offer basic editing features, but some of them may not allow highlight removal. Consider using a more advanced tool or upgrading to a paid version for additional features.

Conclusion

Removing highlights in PDF is a straightforward task once you know the right tools and techniques. Whether you’re using Adobe Acrobat, a free online tool, or Mac Preview, you can quickly and easily remove unwanted highlights from your document. If you run into any problems, troubleshooting the most common issues should help you resolve them. Now you can confidently clean up your PDFs and make them look as polished as you need them to be.
