Can i change the font size in a downloaded book

Ozandy · 01-08-2022, 10:05 PM

i downloaded a pdf book and have converted it to epub via calibre.
once i transferred it to my kindle the font size is too small to read and i cant enlarge it on the kindle itself
i haven't experienced this anytime before
is there anything i can do in calibre to increase the font size and then download to my kindle?

thanks - this is my first post !!

Quick and dirty: Make a backup copy of the epub. Open the epub in calibre's editor. On the left go to the Styles section with the paint brush. For each .css file in there look for all lines starting with

Code:

font-size:

and change whatever is after the colon to 100%; keeping that semicolon. For example, if it's 0.5em; (with or without a semicolon) change it to 100%;.

That will make it a bit ugly since all text, even chapter heads possibly, the same size. But at that point you can use the text size slider of your ereader to adjust it to your liking.

Alternatively to my heavy-handed labor intensive method, figure out how to fiddle with the options in the Convert Books window, under Look & Feel most likely, to get what you want.

No matter what weird code you have, you should be able to increase the fontsize normally on the Kindle.

Could this "conversion" have just made the book into a series of images, one per page?

True conversion should make a normal ebook, with the text in xhtml which you can restyle in the CSS code.
