One T Tools • Creator & Developer

One master icon.
A whole asset pack.

Upload a square master image, check that it is ready for app use, then generate useful iOS and Android PNG icon sizes in one ZIP.

● Image processing stays on your device

PNG, JPG or WebP • 1024×1024 or larger recommended

Choose Master Image

Use a full square image — do not pre-round the corners.

Master Icon

Important: this generator exports square PNG files with no rounded-corner mask. iOS and Android launchers apply their own presentation/masking. Keep important artwork away from the extreme edges.

Android Launcher PNG Sizes

What gets generated?

The ZIP includes a 1024×1024 master plus common iOS raster icon dimensions and classic Android launcher density sizes. The files are organized into ios and android folders so they're easy to find.

Modern platform note

Apple and Android tooling can generate or manage some icon variants differently depending on the current project setup. Treat this as a practical image-size asset generator, not a replacement for Xcode or Android Studio's asset catalog/configuration.
