Indonesian OCR — Extract Indonesian Text from Images and PDFs

Why Indonesian OCR Is Challenging

• Handling Indonesian affixed morphology where prefixes and suffixes create long compound words (mempermasalahkan)
• Processing documents mixing Indonesian with regional languages like Javanese, Sundanese, or Balinese
• Recognizing loanwords from Dutch, Arabic, and Sanskrit that use non-standard letter combinations
• Distinguishing between similar Indonesian words that differ only in prefix (me-, mem-, men-, meny-, meng-)
• Processing older Indonesian documents using pre-1972 spelling conventions (tj→c, dj→j, j→y, oe→u)

How to Extract Indonesian Text (Step by Step)

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

1. Indonesian uses standard Latin alphabet — ensure basic OCR quality with 300 DPI scans
2. For pre-1972 documents, be aware of old spelling: tj→c, dj→j, j→y, oe→u, ch→kh
3. Verify long affixed words are kept intact and not split by the OCR engine
4. Check for correct recognition of repeated words with hyphen (e.g., anak-anak, rumah-rumah)
