To convert a scanned PDF into a searchable PDF, you will need to use OCR software. I use PDF Converter OCR. It’s Mac only. What I like best about the software is its powerful OCR feature and enough output formats. It’s easy to use even for beginners. Step 1. Download and PDF Converter OCR. Open it. Step 2. Drag one or more PDF files into the app. Step 3. Click the output format dropdown list and select the to PDF option. This option will convert a scanned PDF or image to searchable and selectable PDF. Step 4. Click the Convert button. Note. Make sure the OCR feature is turned on. (The OCR feature is enabled by default.)
Please note, if you scan a PDF file, OCR may not work if you do not open the file in the camera app. Make sure you are using the OCR tool with your device's camera. Step 5. If you need to convert a PDF document to another output format (as it may have some formatting information), simply copy and paste the text you want to change and press the Convert button. Note. If you want to change the text or font size to match the size of a scanned document (1-5 PX, for example), use the Scale dropdown menu and select the correct size. Step 6. Click in the conversion progress area. You may need to press some buttons or choose an option. In this app, you cannot select the default setting of font size. If you want to convert a PDF file from one output format to other output format.
