Decide whether you need OCR
Try selecting a word in your PDF viewer. If the page is only an image, OCR can recognize text from its pixels. If it already contains good selectable text, try PDF to Text first and avoid unnecessary reprocessing.
Start with a clean scan
Straighten the page, avoid shadows and make sure small characters remain visible. Low-resolution photos, faded ink and handwriting reduce accuracy. OCR does not recover detail that was never captured. Keep the original scan.
Select Hindi and run a small batch
Open OCR PDF and choose Hindi for Hindi text, or English + Hindi when the page mixes both languages. Recognition runs locally using downloaded OCR models. Start with one representative page. The current limit is 20 pages and a 180-second deadline; split a larger document into manageable parts. A slow phone may need smaller batches even below that limit.
Verify searchable text
Search for a known word in the exported PDF, then compare names, dates and numbers against the visible scan. The PDF retains rendered page images with a searchable text layer; original links, forms and accessibility structure are not retained. OCR is not a certified transcription.
When Hindi search or copy-paste is wrong
Try a short word that is clearly printed in the scan. If it is missing or garbled, confirm the recognition language, straighten the original and try a clearer scan. Compare vowel marks, joined characters, names and numerals especially carefully. Increasing a blurred image’s size does not recreate lost detail. Do not overwrite the original with an unreviewed OCR result, and do not treat handwriting recognition as reliable.
Searchable PDF is different from editable text
The visible page remains an image with recognized text behind it. This makes finding and copying words possible; it does not turn the page into a faithfully formatted Word document. For a text-only draft, run the reviewed searchable PDF through PDF to Text and proofread the reading order. Multi-column pages and tables can be copied in an unexpected order. If you need the original visual layout, keep the searchable PDF as well.
