Welcome to the official blog of App Asset Generator. We publish practical articles for developers, designers, and product managers who ship iOS and Android apps. Topics include App Store Connect and Google Play Console requirements, pixel-perfect screenshot dimensions, Asset Catalog and mipmap structure, and workflows that save time before each release.
What you will find here
- Reference posts—summaries of current icon and screenshot size expectations, with context on when Apple or Google change rules.
- How-to guides—step-by-step instructions that complement our How it works page with deeper examples.
- Product notes—when we add features (such as batch upload or new store sizes), we explain how to adopt them in your pipeline.
Tools on the homepage
Everything we discuss ties back to three free utilities you can use immediately:
- App Icon generator—one square image becomes the full iOS
AppIcon.appiconsetand Androidmipmapset, including round launcher icons. - Screenshot resizer—upload one or more images; receive every standard App Store and Google Play screenshot size in a ZIP.
- Custom resize—set arbitrary width and height for batch jobs such as thumbnails or marketing collateral.
No account is required. Processing happens when you request it; we do not keep your files afterward. Details are in our Privacy Policy.
