Generally, a scanned PDF or a PDF that was created from an image will not be searchable nor editable. So you need a tool with OCR feature which can help you convert these kinds of PDF to be searchable and even editable. OCR stands for optical character recognition, and PDFelement is an all-in-one PDF tool with the OCR functionality. Open your non-searchable PDF into PDFelement, click the “Convert” > “OCR” button, and choose “Searchable Text” or “Editable Text” mode as you want. Editable text is also searchable, however searchable text may not be editable. Get detailed steps about how to convert PDF to searchable PDF.
OCR features include: Searchable PDF, OCR, PDF Annotations, Search, Convert, Output Settings, and Options.
