OCR LAB is a professional offline OCR workstation for Windows supporting 48 languages including rare stock.
Unlike screenshot OCR utilities or Windows OCR wrappers, OCR LAB is built for real scanned documents — TIFF, JPG, PDF, multi‑page batches, archival scans, and high‑resolution pages.
Powered by Tesseract 5.4, written in Rust, and designed for deterministic, structured output, OCR LAB delivers accurate, private, and repeatable document conversion with no cloud, no accounts, and no telemetry.
