OCR을 사용하여 더 나은 결과를 얻는 방법
1. If your PDF file is a scanned file or the image-based file, then you need to perform OCR in order to select or edit text. After opening your PDF file in the program, please click the "Convert" > "OCR" button, then you can choose either "Searchable Text Image" or "Editable Text" mode, click the "Change Language" button to choose the correct language of your PDF content to perform. You can refer to this article about how to edit scanned PDF step by step.
2. If you just want to select/search/copy text instead of editing text, then it is suggested that you can use the "Searchable Text Image" mode to perform OCR. In this way, the newly created PDF file after performing OCR can keep the same layout as your original content, and the text will be searchable and selectable.
