Compress Luma event cover images to a clean 800x800 square

Luma displays event covers as squares across its calendar, event page and embeds, and its own help documentation asks for a 1:1 aspect ratio at 800x800 pixels or larger for the image to look right everywhere it appears. That square requirement is what catches organisers out: a landscape photo that looked fine in a design tool comes back with the sides cut or letterboxed, and a very large export makes the calendar page heavier than it needs to be for a cover that renders a few hundred pixels wide. The fix is unglamorous — resize the source to a square that is at least 800x800, then compress it so the calendar and the event page both load fast. Skwish compresses and resizes images locally in your browser with a live before/after readout per file, so you can see the exact dimensions and the byte weight change at the same time. Batch a whole season of events, export a ZIP. Nothing is uploaded to a server.

Luma cover notes

Use these before you upload or share the page.

Square is the rule. Luma asks for a 1:1 aspect ratio, so crop to a square in the design tool or resize to one before uploading — Luma shows the cover in a square frame regardless.

800x800 is a floor. Upload at least 800x800; larger is fine as long as you compress, because the cover renders small on most surfaces.

Consistent covers read as a series. Compress a whole season at one quality setting so your calendar does not look like ten different events from ten different brands.
