You can export this to a text file or copy and paste it into another program. Plain Text is the default mode and only recognizes the text itself without any formatting or layout detection. GImageReader has two OCR modes: “Plain Text” and “hOCR, PDF”. ![]() As of the date of this post, the Fossies software archive is hosting the manual on its website. The installation of gImageReader comes with a manual as an HTML file that can be opened by any browser. You can then run that file to install the program. From there, go to the most recent release of the program at the top and click Assets to expand the list of files included with the release. To install gImageReader on Windows, go to the releases page on Windows. I have not tested this though, so I do not make any guarantees about how possible it is to get a working version of gImageReader on Mac. Though they do not include a Mac compatible version in the list of releases, it may be possible to get it to work if you use a package manager for Mac such as Homebrew. GImageReader is available for Windows and Linux. I tried all of the Windows-compatible programs and decided that gImageReader was the closest to what I was looking for, a free alternative to ABBYY FineReader that does a pretty good job of letting you correct OCR mistakes and exporting to a searchable PDF. In this post, I will focus on one of these programs, gImageReader, but as you can see on that page, there are many options available on multiple operating systems. You can see the full list of programs on this page. Thankfully, there are many free, open source programs that provide Tesseract with a graphical user interface (GUI), which not only makes Tesseract much easier to use, some of them come with layout editors that make it possible to create searchable PDFs. Additionally, it is fairly difficult to transform a jpg into a searchable PDF with Tesseract. By itself, Tesseract only works through the command line, which creates a steep learning curve for those unaccustomed to working with a command-line interface (CLI). Thankfully, there’s a free, open source alternative for OCR: Tesseract. However, both ABBYY and Acrobat are propriety software with a steep price tag, and while they are both available in the Scholarly Commons, you may want to perform OCR beyond your time at the University of Illinois. If you’re using OCR, chances are you’re working with either ABBYY FineReader or Adobe Acrobat Pro. ![]() Optical Character Recognition (OCR) is a powerful tool to transform scanned, static images of text into machine-readable data, making it possible to search, edit, and analyze text.
