When this tool helps
Color pages cost more to print and look uneven when a scan was made in poor light. Grayscale keeps all detail, while black and white gives a crisp, copier-like page that suits text documents.
Tips for a better result
- Use Grayscale for photos and charts and Black and white for plain text pages.
- Choose Small file if you plan to email the result.
- The pages become images, so run OCR: text from PDF and photo afterward if you need selectable text.
Common problems and how to fix them
The text cannot be selected any more
Pages are saved as images. Use OCR: text from PDF and photo to add a text layer.
Light gray text disappeared in black and white
Black and white turns pale pixels white. Use Grayscale for documents with light text.
