I've encountered this problem with PDFs in general, where the pages are images instead of text. I've learnt to search for the same book/document in epub/mobi format. If I don't find it after searching the web, I will still use the PDF version - either squinting my eyes to read the tiny text or change the orientation to landscape mode (so that the image is a little bit bigger). If none of this works / its too much hassle - I use laptop/phone to read the document

To be honest though, I am not sure if this a pain-point enough for me to pay for a service to convert it to text. In my mind, these are edge-cases.
