Frequently Asked Questions
Answers to common questions about removing visible highlights and study marks from scanned or image-based PDFs.
Can I remove highlights from a scanned PDF?
Yes. You can upload a scanned or image-based PDF and remove visible highlight marks, colored marker strokes, underlines, circles, notes, and study marks while keeping the printed content readable as much as possible.
Is this different from deleting PDF annotations?
Yes. If a highlight is a real PDF annotation layer, a PDF editor may be able to delete it directly. This tool is for scanned PDFs or image-based pages where the highlight is part of the page image and cannot be selected.
Does it work on yellow, pink, blue, or green highlights?
Yes. It can reduce many common highlight colors, including yellow, pink, blue, green, orange, and other marker strokes. Results depend on scan quality and how strongly the highlight covers the text.
Will the text under the highlight stay visible?
The tool is designed to preserve printed text, tables, and page layout while removing visible highlight color. Results are best when the highlight does not fully obscure or damage the original text.
Can I clean a multi-page PDF?
Yes. You can upload a multi-page PDF and clean the pages without manually converting each page into an image first.
Can it remove underlines, circles, and handwritten notes too?
Yes. In addition to highlights, it can help remove visible underlines, circles, margin notes, pen marks, and other study markings from scanned PDF pages.
Can I download the cleaned result as a PDF?
Yes. After cleanup, you can download the cleaned pages as images or export the processed pages back into a PDF.
Is my uploaded PDF private?
