Industry-standard open-source OCR engine for text extraction from images
Apache-2.0
ABOUT
Scanned PDFs, images, and handwritten documents are invisible to search engines, LLMs, and text processing pipelines. Without OCR, every scanned document must be manually transcribed or skipped entirely — a massive bottleneck for document-heavy AI workflows. Tesseract converts rasterized text into machine-readable strings with layout analysis, supporting 100+ languages and output formats including plain text, hOCR, PDF with text layer, and ALTO XML.
