What is Polish OCR & Developer API?
Developer API docs →Polish OCR is the automated process of converting scanned multi-page PDFs up to 1GB and documents into editable, searchable Polish 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. For engineering teams building RAG pipelines, vector search databases, or automated document ingestion, FastOCR also provides a Polish OCR REST API at api.fastocr.org with 50 free pages a month for every signed-in account. The API accepts PDF files up to 1 GiB, and PNG, JPG, JPEG, GIF, WebP and BMP images up to 20 MiB. An image counts as one page.

Why Polish OCR Is Challenging
- Recognizing nine Polish-specific diacritical characters: ą, ć, ę, ł, ń, ó, ś, ź, ż
- Distinguishing between ź (z-acute) and ż (z-dot-above) which look similar in small fonts
- Handling the ł character (l with stroke) which is easily confused with plain l or t
- Processing Polish text with frequent consonant clusters (e.g., szcz, prz, trz) that challenge segmentation
- Preserving the ogonek diacritics on ą and ę which are small hooks below the letters
How to Extract Polish Text from a PDF & Images
- Go to fastocr.org
- Upload your Polish image or PDF. Language is detected automatically.
- Wait for processing — images take seconds, PDFs show a progress bar.
- Download results: searchable PDF, raw text file, or copy text directly.
Tips for Better Polish OCR Accuracy
- Scan at 300+ DPI to preserve the fine diacritical marks that distinguish ź from ż and ą from a
- Verify ł (l-stroke) is not converted to plain l or t — this is a common Polish OCR error
- Check ogonek marks on ą and ę which are small and easily lost in low-resolution scans
- For consonant clusters like szcz, verify all characters are correctly recognized
- Use high-contrast scans to preserve the dot above ż and acute accent on ź, ć, ń, ś
Common Use Cases for Polish OCR
- Digitizing Polish legal documents, contracts, and court rulings
- Extracting text from Polish government forms and official certificates
- Converting scanned Polish academic papers and university dissertations
- Processing Polish business invoices and commercial correspondence
- Archiving Polish historical documents and World War II-era records
