In Adobe Express werden meine importierten Bilder noch scharf angezeigt. Nach export (herunterladen als png und/oder jpeg) sind die Grafiken total unscharf.
I think the image appears sharp when viewed at 500% while editing because elements within the project haven't been rastered to the project dimensions yet. Viewing at 100% when editing then comparing the output at 100% would be a better test to gauge the output quality, at least that's my understanding.
Thanks for posting and welcome to the community - I will be honest, 1080px with that amount of text is probably not going to be very high-resolution/reading friendly.
If you’re utilizing this for social media, I would recommend using much larger text size. In general, most social media apps/sites don’t do well with super HQ images as it is.
