Greek OCR — Image to Text & PDF

Why Greek OCR Is Challenging

• Distinguishing Greek letters from visually similar Latin letters (e.g., v/ν, p/ρ, u/υ, x/χ)
• Recognizing monotonic diacritical accents (tonos and dialytika) on lowercase vowels
• Processing historical polytonic Greek texts with breathings and multiple accents
• Handling mathematical and scientific notation mixed with Greek textual content

How to Extract Greek Text from a PDF & Images

1. Go to fastocr.org
2. Upload your Greek 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 Greek OCR Accuracy

1. Scan at 300 DPI to preserve small vowel accent marks (tonos) and dialytika
2. Verify that Greek character representations are not replaced by similar-looking Latin letters in the output
3. For polytonic Greek (ancient texts), check breathing marks carefully, as standard OCR defaults to monotonic
4. Use high-contrast scans to distinguish ι (iota) from Latin I and υ (upsilon) from Latin u
