Sometimes when we open a PDF file, we will find that the fonts are blurred and cannot be edited. This kind of situation is usually because the PDF file is converted from a scanned copy or an image, even with a special PDF editor. If it cannot be edited, of course, it is not completely impossible to edit. We can first recognize the text on the picture into an editable PDF format through OCR recognition technology, and then we can edit it normally through an ordinary PDF editor.

Let's take a look at OCR first. OPTichacteion (OPTichacteion) text identification refers to the whole process of character printing on electronic device inspection paper and then translating the shape into computer text according to the character identification. The key index values for determining the performance of the OCR system are rejection rate, Misunderstanding rate, identification rate, user interface friendliness, product stability, ease of use, and feasibility.
