Complete Guide to Chinese OCR
Learn how to extract text from Chinese documents, scanned books, and images using modern OCR technology. Free for images, with Simplified and Traditional Chinese support.
The Challenge: Chinese Text in Images and PDFs
Chinese OCR faces unique hurdles due to the density and complexity of Hanzi. Standard English-focused OCR engines often garble Chinese text because:
- Thousands of unique characters to recognize
- Intricate stroke patterns that easily blur in low-resolution scans
- Varied layouts including vertical and horizontal text orientations
- Mixtures of Simplified and Traditional characters in the same document
The Solution: Specialized Chinese OCR
Modern OCR engines read Chinese text well. FastOCR reads Chinese text from images and PDFs. On our Chinese test page (a printed page, run on 25 October 2026) it scored a character error rate (CER) of 1.0. CER is the share of characters that are wrong, so lower is better.
