OCR - Image Reader

OCR - Image Reader is a Chrome extension from developer brian.girko that adds a toolbar button for on-the-fly optical character recognition. Press the button, drag a selection over any region of the active window, and the extension reads the text inside it using a Tesseract-based engine that supports over 100 languages with automatic orientation and script detection. A second engine option, IBM Granite-Docling, goes further and preserves headings, lists, bold and italic styles, tables and even mathematical equations instead of returning flat text. Everything runs offline in the browser, with no server round trips apart from a one-time download of the language training data.

Region-select OCR

Click the toolbar icon, draw a rectangle over any part of the active window, and the text inside is recognised immediately.

100+ language engine

A Tesseract.js engine recognises plain text in over 100 languages with automatic text orientation and script detection.

Layout-aware Granite-Docling engine

Switch to IBM Granite-Docling to retain headings, lists, bold and italics, tables and mathematical equations instead of losing layout.

Private offline processing

The OCR runs entirely in the browser with no server calls; only the language database is downloaded once and then cached.
