Polish OCR — Extract Polish Text from Images and PDFs

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 (Step by Step)

1. Go to fastocr.org
2. Upload your Polish image or PDF. Language is detected automatically.
3. Wait for processing — images take seconds, PDFs show a progress bar.
4. Download results: searchable PDF, raw text file, or copy text directly.

Tips for Better Polish OCR Accuracy

1. Scan at 300+ DPI to preserve the fine diacritical marks that distinguish ź from ż and ą from a
2. Verify ł (l-stroke) is not converted to plain l or t — this is a common Polish OCR error
3. Check ogonek marks on ą and ę which are small and easily lost in low-resolution scans
4. For consonant clusters like szcz, verify all characters are correctly recognized
5. Use high-contrast scans to preserve the dot above ż and acute accent on ź, ć, ń, ś
