Are uploaded icons sent to a server?

No. The image is decoded, resized, and zipped locally in the browser.

Can transparent icons be generated?

Yes. Transparent pixels are preserved for PNG output unless a background color is explicitly enabled.

Browser-only asset builder

Drop one icon and export a complete Xcode-ready AppIcon.appiconset ZIP without flattening alpha.

Choose source icon PNG, SVG, JPEG, or WebP. Best results start at 1024 x 1024 or larger.

Your source file stays local in this browser tab.

No icon selected

Generated files will appear after loading an image.

PNG alpha is preserved by default. Enable background fill only when a store, platform, or design rule requires an opaque icon.

The ZIP contains `AppIcon.appiconset`, `Contents.json`, and PNG files named by idiom, point size, scale, and pixel size.

The browser resizes and packages the image locally. No upload endpoint is used by the workflow.
