EPUB, MOBI, AZW3 — how the three formats differ
EPUB is the open e-book standard: XHTML and CSS in a ZIP package, reflowing to any screen size. MOBI and AZW3 are Amazon's Kindle formats — AZW3 (KF8) is the newer one with better layout; both are proprietary, which is why this page converts EPUB locally (to PDF, TXT or HTML) while Kindle targets go through the external Calibre toolchain.
EPUB = open, reflowable, works on every reader except Kindle-native; MOBI / AZW3 = Kindle-only, written by Calibre or a server bridge. DRM-protected books bought from a store cannot be converted by any honest tool. To read EPUB in the browser use the EPUB Viewer / Editor; to slim one down see EPUB Compress.
