What OCR Can Handle

- Handwriting: Limited support depending on clarity
Accuracy Tips
Higher resolution input produces better results. Aim for at least 300 DPI on scanned documents. Straighten skewed images before processing. Clean backgrounds with high contrast between text and background yield the highest confidence scores.
Privacy
