Batch OCR in Multiple Languages — Extract Text in Japanese, Chinese, and More

OCR for non-Latin scripts and languages beyond English requires specialized recognition models. Our free Batch OCR tool includes built-in support for 8 languages — including Japanese and Simplified Chinese — so you can extract text from multilingual document batches without language-switching tools or multiple subscriptions.

This guide covers which languages are supported, how to process multilingual batches, and what to expect for accuracy in each language.

Supported Languages — What Is Available

The free Batch OCR tool supports these 8 languages:

Language	Script	Notes
English	Latin	Default — highest accuracy
Spanish	Latin	Includes accented characters (á, é, ñ, ü)
French	Latin	Includes accents and cedilla (ç)
German	Latin	Includes umlauts (ä, ö, ü) and eszett (ß)
Portuguese	Latin	Brazilian and European Portuguese
Italian	Latin	Standard Italian character set
Chinese (Simplified)	CJK	Mainland China standard characters
Japanese	CJK + Latin	Hiragana, katakana, kanji, romaji

Traditional Chinese (used in Taiwan and Hong Kong) is not currently supported — Simplified Chinese only. If you need Traditional Chinese OCR, specialized tools are required.

Batch OCR for Japanese Images

Japanese text presents unique OCR challenges: three character systems (hiragana, katakana, and kanji) often appear together in the same document. Our tool handles all three, including vertical text layouts common in traditional Japanese documents and manga.

For Japanese batch OCR:

1. Select Japanese from the language dropdown before processing
2. For best accuracy, use horizontal text layouts if you have control over the source documents
3. Vertical text (tategumi) is recognized but accuracy may be lower than horizontal layouts
4. Furigana (small reading aids above kanji) may be extracted separately — this is expected behavior

Common Japanese batch OCR use cases: extracting text from Japanese product packaging photos, digitizing Japanese business cards, processing Japanese-language receipts and invoices, and extracting text from Japanese educational materials or manga panels.

Batch OCR for Simplified Chinese

Simplified Chinese OCR processes documents in the standard character set used in mainland China and Singapore. This includes modern Chinese characters but not traditional character forms.

For Chinese batch OCR:

1. Select Chinese (Simplified) from the language dropdown
2. Mixed Chinese-English documents are handled — the tool recognizes both scripts in the same image
3. Handwritten Chinese is significantly harder than printed text — accuracy varies widely based on writing clarity
4. Classical Chinese texts using archaic characters may produce lower accuracy

Common Simplified Chinese batch OCR use cases: extracting text from Chinese-language product images and packaging, processing Chinese invoices and receipts, digitizing Chinese-language business documents, and extracting text from screenshots of Chinese apps or websites.

Processing Mixed-Language Batches

If your batch contains images in different languages, the most accurate approach is to process them in separate batches by language — select English for the English images, then switch to Japanese for the Japanese images.

However, if the languages are similar (Spanish and Portuguese documents mixed together, for example), you can often run them in a single batch using the primary language of the documents. Latin-script languages share enough character recognition that cross-language accuracy is acceptable for many use cases.

For documents that contain two languages in the same image (a bilingual form or a document with English headers and Chinese body text), select whichever language is dominant in the document. The tool will attempt to recognize both scripts but accuracy for the secondary language will be lower.

What to Expect — Accuracy by Language

OCR accuracy varies by language based on character complexity and training data quality:

Language	Typical Accuracy (clean printed text)	Notes
English	97-99%	Best performance — most training data
Spanish, French, German, Italian, Portuguese	94-98%	High accuracy; accented characters occasionally missed
Chinese (Simplified)	90-96%	Accuracy lower for uncommon characters
Japanese	88-95%	Hiragana/katakana very accurate; complex kanji variable

All figures assume clean, high-contrast, 300 DPI or higher images with printed (not handwritten) text. Low-quality images reduce accuracy significantly across all languages.

Frequently Asked Questions

Can I extract text from Japanese manga or comics with batch OCR?

Yes, though with some caveats. Speech bubble text in manga is usually printed text (not handwritten) and OCR handles it reasonably well. Sound effects (onomatopoeia) in stylized fonts may not extract accurately. Handwritten-style fonts common in manga are harder to recognize than standard printed fonts.

Does the tool support Traditional Chinese?

Not currently. Only Simplified Chinese is supported. For Traditional Chinese documents (Taiwan, Hong Kong), you will need a specialized OCR tool that includes Traditional Chinese support.

Can I process a batch with some English and some Japanese images?

Yes, but for best accuracy, process them in separate sessions — one with English selected, one with Japanese selected. This ensures the OCR engine is optimized for each language. Processing Japanese images with the English setting will produce poor results for Japanese text.
