I will provide a simple assumption and then, i will suggest you a website for that purpose. I simply assume that when a document is converted to a PDF, it changes the encoding of the document. So, every PDF may not be interpreted as a simple document which easily allows copying and pasting. Now , a website. On other websites, t will give you Screenshots of the PDF file pages as an 'extracted dataâ but on I LOVE PDF DOT COM , it uses OCR Technology and converts the data into MS WORD or MS EXCEL or any other standard editable document. And plus point is , it is free. Other services may ask for fees. Thanks.
The one that isn't an image is the text that you can read. If the text looks like a script, you have a PDF with a text overlay (PNG). Most likely, the text will not be very readable due to an excessive amount of lines with white or bold text. It is best to read the text by copying it with OCR to another document. If the text is not clear, then you have an image. If the background was taken from the background in some photograph, then it's a background, but if it wasn't, you have a PNG. If you find that you have an image in your PDF file, it's most likely from a photo file. Most likely the PNG you have is an altered background. It's best to read the background on another page than it will be visible in your PDF file. If you are able to.
