I would like to be able to make the PDFs I read more 'readable'. For example, in the same way that I can reflow, restyle and reformat the presentation of online articles using Instapaper and Pocket.
Is there a way I can do this with Adobe and Foxit Readers? I'd like to change the typeface, size, spacing, flow (columns) and contrast. Otherwise, are there any readers that will allow me to do this?
