What gImageReader is
gImageReader is a free desktop OCR front end to Tesseract for Linux and Windows. It imports PDFs and images from disk, scanning devices, the clipboard, and screenshots, and can process multiple items in one batch. Recognition areas may be selected manually or automatically. Recognized text appears beside the source image for review and post-processing, including spellchecking. Output can be saved as plain text or hOCR documents, and PDFs can be generated from hOCR. The project lists international language support; language definitions are selectable through the integrated tessdata manager or can be installed manually. The Windows installer bundles the needed Tesseract files. gImageReader is open source under GPL-3.0. Help is available through the issue tracker, maintainer email, and FAQ. GitHub reports no SECURITY.md policy and no published security advisories. The listed Free plan costs nothing, with no free trial because the software is free.
