What is Kannada OCR & Developer API?
Developer API & RAG Docs →Kannada OCR is the automated process of converting scanned multi-page PDFs up to 1GB and documents into editable, searchable Kannada text while preserving accents, complex ligatures, and native character shapes. FastOCR reads printed text in this script and generates full-text searchable PDFs with selectable text overlays at near-instant speed. For engineering teams building RAG pipelines, vector search databases, or automated document ingestion, FastOCR also provides a high-speed Kannada OCR REST API at api.fastocr.org with 10 free pages a month for approved accounts. The API accepts PDF files only.

Why Kannada OCR Is Challenging
- Recognizing the rounded character forms unique to Kannada script which differ from Telugu
- Handling vowel marks (ottakshara) that stack above or below consonants in complex combinations
- Distinguishing visually similar Kannada characters like ಕ/ಗ, ಚ/ಜ, ತ/ದ in small font sizes
- Processing documents mixing Kannada with English, Hindi, or Tulu text
- Correctly segmenting conjunct consonants that form complex ligatures

Tips for Better Kannada OCR Accuracy
- Scan at 300 DPI minimum to preserve the rounded Kannada character forms and small vowel marks
- Ensure even lighting — shadows can obscure the small marks above and below Kannada characters
- Verify conjunct consonants are recognized as single glyphs rather than split into individual letters
- For mixed Kannada-English documents, check that script boundaries are correctly detected
