How to Remove Shadows, Sharpen Text and Enhance your Scans?

DocScan automatically improves your scans by cropping, correcting perspective, and applying color enhancement. You can further fine-tune your scans to remove shadows, sharpen text, and improve clarity using the adjustment tools.

➊ Choose a Color Mode

After scanning, go to Image Editing. Use the bottom toolbar to switch between color modes:

• Photo: Keeps the original appearance — ideal for photos or drawings
• Color: Enhances color and contrast — great for forms, receipts, or diagrams
• B&W: Converts the image to pure black and white — best for documents with text

The bottom preview image shows the current enhanced result in real time.

➋ Pick an Enhancement Method (For Color & B&W only)

Tap the bottom preview image  or the “Edit” button to open the color editing screen.

🔸If you select Color or B&W, three enhancement options will appear:

• Bold: Produces high-contrast, bold text, but the shadow removal effect is weakest. — perfect for scanned text
• Fine: Keep more details in picture regions. The shadow removal effect is next strong. — good for diagrams or detailed images
• Clean: Reduces strong shadows — recommended when scanning under uneven lighting

➌ Fine-tune the Image

1. Use sliders to adjust Brightness, Shadow Removal Level, or Saturation.

   

2. If you selected Color or BW, tap the  Adjust button at the bottom left to access the full adjustment panel.
