Start with honest expectations
Urdu OCR (اردو او سی آر) is harder than English OCR. Connected letterforms, stacked Nastaliq calligraphy, and missing or dense diacritics all raise the error rate. Photo2Text is best-effort: a sharp scan of plain print can look great; a dim, tilted phone photo of ornate type will not. Improving the image usually beats switching tools.
Lighting and contrast
- Use diffuse daylight or a lamp that does not create a hotspot glare.
- Dark ink on light paper outperforms faded photocopies.
- Avoid patterned tablecloths and busy posters behind the page.
Cropping and framing
Fill the frame with the paragraph you need. Margins, stamps, seals, and neighboring columns add noise. If a page has multiple columns, crop one column at a time. Keep the phone parallel to the page so lines stay roughly horizontal.
Resolution without excess
Text should look crisp when viewed at 100% on your screen. That is a better rule of thumb than chasing a specific DPI number. Extremely large photos mostly cost time; our tool downscales widths above 2000px before OCR runs.
Language selection
Open the Urdu image to text tool, choose Urdu (or English + Urdu for mixed pages), then Extract. After the first model download, switching images with the same language reuses the worker for the session.
