Remove Highlight from PDF

How to Remove Highlights from a PDF

You can remove one or all supported highlights from a PDF without deleting the text underneath them. Use the tool above to scan the document, clear selected highlight annotations, and download a new clean copy.

Quick Answer

To remove highlights from a PDF, add the file, let the tool scan for supported highlight annotations, choose one or all highlights, and export the cleaned PDF. The original document is not overwritten.

Removing a highlight annotation normally removes the colored overlay while keeping the original text, images, page dimensions, and layout. It does not automatically delete text that was highlighted.

How to Remove Highlights Online

1. Add your PDF. Drag and drop a file or select it from your device.
2. Scan the document. The tool looks for supported text highlight annotations across the PDF.
3. Review the results. Check how many highlights were found and where they appear when page information is available.
4. Choose what to remove. Clear all detected highlights or select individual items when selective cleanup is supported.
5. Download a new PDF. Export the cleaned copy and keep the original file separately.

What This Tool Removes

The tool targets supported PDF highlight annotations. These are usually separate markup objects placed over text or a page region. They may include common text highlights created by PDF readers and annotation editors.

• Text highlight annotations.
• Colored highlight markup.
• Selected highlights on specific pages.
• All supported highlights in a document.

The exact result depends on how the source application created and stored the annotation.

What Remains in the PDF

Removing a highlight is different from deleting the document content underneath it. In the normal workflow, the following items remain:

• The original selectable PDF text.
• Images and page graphics.
• Page size and document layout.
• Comments, links, drawings, and other annotations that were not selected.
• Text color and formatting that belonged to the original document.

For example, if a sentence was highlighted in yellow, removing the highlight should leave the sentence readable without the yellow annotation layer.

Why Some Highlights Cannot Be Removed

Not every colored area in a PDF is a separate highlight annotation. A highlight may have been flattened into the page content, printed into a scanned image, or created as a colored shape or drawing. In these cases, a PDF viewer may display the color but the annotation remover cannot identify it as a normal highlight object.

Other possible causes include:

• The file contains overlapping annotations.
• The highlight was flattened before the PDF reached you.
• The color is part of a scanned page image.
• The visible area is a colored rectangle or drawing instead of a text highlight.
• The PDF uses an annotation structure that is not supported by the current processor.

Highlight Annotation Versus Flattened Highlight

A normal highlight annotation can usually be selected, moved, or deleted in a PDF editor. A flattened highlight is drawn into the page content and behaves more like part of the document itself. Removing a flattened highlight may require editing the page content, rebuilding the page, or using OCR and image-processing techniques.

This tool is designed primarily for removing supported highlight annotations. It does not promise to erase every colored region from every scanned or flattened PDF.

Remove Highlights Without Removing Comments

Highlights, comments, sticky notes, drawings, links, and stamps are different types of PDF annotations. The default workflow targets highlights only, which lets you clean marked passages while keeping other review information. If you want to remove every annotation, use a broader PDF annotation-removal tool instead.

How to Check the Cleaned PDF

After downloading the output, open it in a PDF viewer and check a few pages before sharing the file:

1. Open the cleaned PDF in a browser viewer, Adobe Acrobat, Preview, or another PDF reader.
2. Check pages that contained the most highlights.
3. Confirm that the text is still selectable and readable.
4. Check that comments, links, and other annotations you wanted to keep are still present.
5. Save the cleaned file under a new name so the original remains available.

Common Reasons to Remove PDF Highlights

• Prepare a clean final version after document review.
• Remove temporary study or proofreading marks.
• Print a document without colored overlays.
• Share a readable copy with someone who does not need the review markup.
• Clear old highlights while keeping the original PDF text and layout.

When to Use Another PDF Tool

Use a PDF annotation remover if you also need to delete comments, sticky notes, drawings, stamps, links, or other markup. Use a PDF editor or image-processing workflow if the highlight is flattened into the page content or embedded in a scanned image.
