- App Icon Generator — upload one square image (1024×1024+) and get a ZIP with a complete iOS
AppIcon.appiconset(validContents.jsonincluded) and every Android mipmap density (mdpi→xxxhdpi), including the round launcher icon and the 512×512 Google Play Store icon. Drop straight into Xcode / Android Studio. - Android Icon Generator — same engine, Android-only: https://www.appassetgenerator.com/android-icon-generator
- Screenshot Resizer — batch-resize screenshots to every official App Store Connect and Google Play Console size (iPhone, iPad, Android phone/tablet).
- Favicon Generator — pick from 250+ built-in icons or upload your own, get
favicon.ico,apple-touch-icon.png, Android Chrome icons,site.webmanifest, and a ready-to-paste HTML snippet. - File Converter — image, audio, video, and document conversion.
- PDF Editor — merge, split, rotate, and edit PDFs in the browser.
General image editors don't know Apple's Asset Catalog schema or Android's mipmap naming rules, and store consoles reject screenshots that are off by a few pixels. This encodes those rules so you upload once and get a submission-ready ZIP.
