How it works

One image in, a whole icon set out

An iOS app icon alone is 16 files at different sizes, each listed in a Contents.json. Asset Catalog Creator draws, names and lists them all, straight into your project.

Sixteen files from one picture

This is the iOS app icon Asset Catalog Creator made from the White Noise icon above, drawn to scale. You never need to look a size up again.

From icon-20@2x.png at 40 × 40 pixels to ios-marketing.png at 1024 × 1024, for the Home Screen, Spotlight, Settings and notifications on iPhone and iPad, and the App Store.

Features

Fits the way you work

Size VariationsDrop in the same artwork at several sizes or shapes, and each file is made from the closest match in size and aspect ratio.
Batch ExportDrop in a folder of artwork and every image becomes an image set of its own, named after its file.
Merges into your catalogAdd to the asset catalog you already have, keeping its folders. If a name is taken, choose to append to it, overwrite it or use a new name.
Checks your imagesWarns you when an image is too small or the wrong shape, and removes the alpha channel from opaque icons so App Store Connect accepts them.
Vectors stay vectorsPDF and SVG artwork can be saved as single vector PDF assets, so it stays sharp at any size.
Remembers where you wereRecent images and output folders are a click away, and your settings sync between Macs through iCloud.
