Features

• Fast and accurate, multi-language support (-l, --lang), powered by Apple's industry-strength Vision framework.
• Supports all common input image formats: PNG, JPEG, TIFF and WebP.
• Supports PDF input (the file gets converted to images first). This tool does NOT assume a file is PDF just because it has a .pdf extension, you need to pass -p, --pdf flag.
• Outputs extracted text only by default, but can output in JSON format containing confidence of recognition for each line with -j, --json flag.

Demo

Below is the output of running the tests:

                 file_path

Extract text from an image or PDF using Apple's Vision framework.

positional arguments:

  -l LANG, --lang LANG  Specify the language for text recognition (e.g., eng,

                        Traditional Chinese). Default is 'zh-Hant', which
                        works with images containing both Chinese characters

  --pdf2image-dir PDF2IMAGE_DIR
