Thai Text Extractor
Extract Thai text from images and documents. Free.
What Is This Tool?
Thai script has no spaces between words, stacks tone marks and vowel signs above and below consonants, and uses a completely distinct alphabet — three separate challenges most general-purpose OCR isn't built to handle together.
How It Works
Recognizes Thai script including its stacked diacritics, without relying on spacing to separate words.
Key Capabilities
Stacked mark recognition
Thai vowels and tone marks stack above and below the consonant line; the model reads the full stacked glyph correctly.
No word-boundary assumption
Like Chinese, Thai doesn't use spaces between words, so segmentation doesn't rely on whitespace.
Full consonant and vowel coverage
Recognizes Thai's complete alphabet, distinct from any Latin or CJK script.
How to Use

Photos, scans, or screenshots all work.

Frequently Asked Questions
How does Thai OCR handle the complex script?
Thai script uniquely lacks spaces between words and uses above/below character placement for vowels and tones. Our OCR engine handles these complexities by recognizing the full Thai character set including consonants, vowels, tone marks, and Thai numerals in their correct spatial relationships.
Who uses this tool professionally?
Thai tourism businesses extract text from promotional materials for multilingual website creation. International companies process Thai invoices and receipts for accounting departments. Thai expatriates digitize personal documents for immigration and governmental applications.
Can it handle Thai-English mixed text?
Yes. Thai documents frequently include English words, brand names, and numbers. The OCR engine extracts both Thai and Latin scripts accurately in a single pass, making it ideal for Thai business correspondence, academic papers, and product documentation.
Is my Thai document kept private?
Yes. All processing happens locally in your browser. Thai documents are never uploaded to any server.
