Czech OCR — Image to Text & PDF

Why Czech OCR Is Challenging

• Recognizing the háček (caron) on ě, š, č, ř, ž which can be mistaken for an acute accent in low-quality scans
• Distinguishing ě (e with caron) from plain e and ı in small font sizes — the caron is a small V-shape
• Handling the uniquely Czech letter ř which combines a háček with a serifed letterform
• Processing the ring diacritic on ů which is easily confused with plain u or the degree symbol
• Distinguishing ď and ť from their plain forms d and t — the háček sits beside these tall letters, not above them

How to Extract Czech Text from a PDF & Images

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

1. Scan at 300+ DPI to preserve the háček (caron) which is a small V-shape easily lost at low resolution
2. Verify that ř is not misread as r, ž, or š — the caron on ř is distinctive and unique to Czech
3. Check ů (u-ring) is preserved and not replaced with plain u, ú, or the degree symbol °
4. For ď and ť, the háček shifts to a comma-like mark beside the tall letter — verify this is correctly recognized
5. Review ě carefully — it looks similar to e-with-acute (é) and is a common OCR confusion point
