About This Feature
Overview
Scan Enhancement is a scanned-document optimization feature in the WPS PDF component on Windows. It is designed to improve the overall visual appearance of scanned PDF pages.
Its main capabilities include:
- Enhance scanned pages: Apply preset styles from the Scanned Document tab to improve page appearance quickly.
- Compare enhancement results: Switch between the original view and different enhancement effects to choose the most suitable result.
This feature is useful for scanned contracts, archived paper materials, forms, study handouts, and other image-based PDF files. When a scanned page contains shadows, screen patterns, or unclear text, Scan Enhancement can help you preview and save a cleaner result more efficiently.

| Capability Summary | WPS PDF provides preset scanned-document styles, including Original, Smart Optimization, Shadow Removal, Descreen, and Text Enhancement. | Microsoft Word can open a scanned PDF and convert it into an editable Word document, but the converted file may not keep perfect page-to-page correspondence with the original. | Google Drive can scan documents on mobile devices and save them as searchable PDFs, while the web version does not provide scanning. | Notion can import PDFs, but scanned or image-only PDFs are not reliably searchable unless OCR is performed first. | Adobe Acrobat provides scanned-PDF enhancement settings such as deskew, background removal, descreen, and text sharpening, and it can work with OCR options. |
| Official Source | — | Scan and edit a document | Scan documents with Google Drive | Import data into Notion | Scanned PDF settings |
Advantage: You can switch among multiple scanned-document enhancement presets directly inside the same PDF workspace before saving.
Overall Conclusion
If your main goal is to improve the visual quality of an existing scanned PDF quickly, WPS offers a direct preset-based workflow inside the PDF workspace. Microsoft focuses more on converting PDFs into editable documents, Google focuses more on mobile scanning, Notion focuses more on content import and organization, and Adobe provides more detailed scan-enhancement controls.
Use Cases

| 3 | Comparing results before saving | General office users | It is hard to decide which enhancement works better | Switch between Original and different presets before saving |
