Yes — that is the advantage of rendering EPUB to an image: the page is rasterized exactly as it displays, with fonts baked into the pixels. The recipient sees the precise layout regardless of which fonts they have installed, unlike sending an editable document that may reflow on their machine.
Yes — uploaded EPUB files and the rendered images are processed in isolated workers and deleted within minutes. We never read, store, or share the document contents. See /privacy/.
You are viewing a raster image, so zooming past its native resolution shows the pixels. Re-render the EPUB at 300 DPI for a sharper SVG that holds up when enlarged or printed. For infinite-zoom output, render to SVG instead where the source contains vector content.
