How to translate a book/text from pdf to epub by hand?

Question

Electronic books

I have an e-book with a resolution of 1024x758px. I often encounter such a problem as the inconvenient use of pdf files. All the text on the book is very small, which terribly infuriates. In the meantime, I'm downloading novels that I've already prepared, and so on. in epub format and they look lovely. Readable text, +/- capital letters, in general, is convenient. It's real to do. Therefore, the question is how to do it yourself? Are there any services where you can specify the size of the text and so on, or any other means in order to translate the text into a readable form
