How to Improve Image Quality for Better OCR Results

Getting the best OCR results starts with high-quality images. Here are the key factors that impact text extraction accuracy:

## Lighting and Contrast
Proper lighting is crucial for OCR success. Ensure your images have:
- Uniform lighting without shadows
- High contrast between text and background
- Avoid glare and reflections

## Resolution and DPI
Higher resolution images generally produce better OCR results:
- Minimum 300 DPI for scanned documents
- Clear, sharp text without blur
- Avoid pixelated or low-resolution images

## Image Format and Quality
Choose the right format for your needs:
- PNG for screenshots and digital images
- JPEG for photographs (but be mindful of compression)
- TIFF for archival quality scans

## Pre-processing Techniques
Sometimes simple adjustments can dramatically improve results:
- Adjust brightness and contrast
- Remove noise and artifacts
- Straighten skewed text
- Crop to focus on text areas
