Compress itch.io cover images so listings stay sharp and light

itch.io shows your project cover in browse lists, search results and recommendations, so it is the single image most people see before they ever reach your page. The recommended listing cover is 630x500 pixels, with 315x250 as the minimum — smaller art gets scaled and looks soft on high-density displays, while a huge PNG just makes your listing load slowly for everyone. itch.io also lets you upload a banner that replaces the title above your description, and a semi-transparent PNG or an animated GIF works there, which is exactly where people accidentally ship multi-megabyte files. Skwish compresses and resizes images locally in your browser with a live before/after readout per file, so the cover lands on 630x500 and the banner stays light, transparency intact. Batch a whole project's art, export a ZIP. Nothing is uploaded to a server.

itch.io art notes

Use these before you upload or share the page.

630x500 recommended, 315x250 minimum. Cover art is shown small in listings, so detail matters less than contrast and a legible title at thumbnail size.

The banner replaces your title. Because it replaces the page heading, keep the project name inside the banner image itself and keep it readable when scaled.

Keep transparency where you use it. Banner PNGs are often semi-transparent; a compressor that flattens onto white leaves a visible rectangle against the page theme.
