Chinese OCR — Extract Chinese Text from Images and PDFs

Why Chinese OCR Is Challenging

• Recognizing over 50,000 possible Chinese characters with complex stroke patterns
• Supporting both Simplified Chinese (简体) and Traditional Chinese (繁體) character sets
• Handling vertical text layouts found in traditional Chinese publications and calligraphy
• Distinguishing visually similar characters like 己/已/巳, 戊/戌/戍/戎 with minimal stroke differences
• Processing documents mixing Chinese characters with pinyin romanization and English text
• Segmenting Chinese text which has no spaces between words or sentences

How to Extract Chinese Text (Step by Step)

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

1. Use 300+ DPI scans to preserve fine stroke details that distinguish similar Chinese characters
2. Specify Simplified or Traditional Chinese if your OCR tool supports language hints
3. For vertical text documents, ensure the scan orientation is correct before processing
4. Review output for commonly confused character pairs like 人/入, 土/士, 未/末
5. Crop decorative borders and seals from documents to avoid noise in OCR output
