App Icon Pack Maker

App Icon Pack Maker is a desktop icon composition studio and multi-platform icon
bundle generator for Linux, Windows, macOS, Android, iOS, Snap, and Web apps.
An independent Linux desktop alternative to traditional icon editors for composing
adaptive 1024x1024 master icons and exporting production-ready multi-size icon
packages in one click.

Key Features:
- Master Icon Composer: Load PNG, JPEG, WebP, or SVG artwork onto a 1024x1024
RGBA canvas; apply squircle, rounded-rectangle, circle, or full-bleed masks,
configurable inner padding, linear gradient or solid backdrops, subtle border
strokes, and Gaussian drop shadows.
- Multi-Platform Pack Generator: Export Windows multi-size .ico (16, 24, 32, 48,
64, 128, 256), macOS .icns (ICNS header with ic07/ic08/ic09/ic10 PNG chunks),
Linux hicolor PNG tree (16..512), Snap 512x512 icon, Android mipmaps
(mdpi..xxxhdpi), iOS AppIcon.appiconset with Contents.json, and Web Favicon
pack with site.webmanifest.
- Pixel Grid Inspector & ZIP Export: Preview actual downsampled 16x16, 32x32,
64x64, 128x128, and 512x512 renders side by side on dark and light surfaces
with a pixel-grid zoom inspector, and package the complete output tree into
a .zip archive.
