Greetings,

When downloading books from zlibrary, the top option is the format which is stated in the description, with “basic format” added in the end. The rest of the options may include the same format without the “basic format” tag in the end and they are slightly bigger.

What’s their difference? Is it the same document re-formated to the same format thus making it slightly bigger or does it have anything extra?

Like, supposing there’s a book which is a pdf. The options may be:

• pdf basic format 1.2mb
• pdf 1.25mb
• epub 1mb

What’s the difference between the first two?

PS. My first post on lemmy!🙃
