Tesseract is one of the most accurate open source OCR engines. All result documents can be uploaded to the cloud for many purposes. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Tesseract OCR Engine Optical Character Recognition (OCR) is a method by which software "reads" the text characters to preform text recognition from an otherwise flat, scanned image.
