Icon Foundry

An app icon is not one image. It is a system of sizes, masks, appearances, and platform rules. Icon Foundry lets you design that system as one editable source—and turn it into release-ready assets without rebuilding the same artwork in multiple tools.

PURPOSE-BUILT FOR ICON DESIGN

Unlike a generic drawing canvas or a simple icon resizer, every part of Icon Foundry understands the final destination. Work on a precise 1024 × 1024 master, assign platform roles to layers, inspect safe areas and masks, and render every target directly from the source design.

BUILD WITH EDITABLE LAYERS

• Create shapes, text, and SF Symbols on the canvas
• Import SVG, PDF, PNG, and JPEG artwork by file picker or drag and drop
• Keep original SVG artwork as vector data for crisp rendering at every size
• Organize layers with groups, alpha masks, locking, isolation, search, and reusable layer styles
• Position, resize, rotate, align, duplicate, and nudge artwork with mouse or numeric precision

CREATE DEPTH WITHOUT FLATTENING

Combine solid fills, multi-stop linear, radial, and freeform gradients with strokes, blend modes, opacity, drop and inner shadows, outer glow, Gaussian blur, and Liquid Glass controls. Effects stay editable and use the same renderer on the canvas and in final output.

DESIGN A SYSTEM, NOT A SINGLE STATE

Start with a shared Base Design, then create platform-specific designs, Dark, Clear, Tinted, or Mono appearances, and exact-size overrides. Icon Foundry automatically resolves the right design for every preview and exported asset.

SEE PROBLEMS BEFORE USERS DO

Preview iOS, iPadOS, macOS, watchOS, Android, Windows, and website icons at real output sizes. Switch masks and evaluation backgrounds, show pixel grids and platform-safe guides, and run built-in validation for transparency, missing artwork, unavailable fonts or symbols, invalid geometry, Android safe-zone issues, and export-role coverage.

SHIP COMPLETE PLATFORM PACKAGES

Export any combination of:

• A transparent or opaque 1024 px PNG master
• Icon Composer-ready Apple layer sources, current and legacy Xcode asset catalogs, macOS iconset and ICNS files, and Apple Watch assets
• Android adaptive, monochrome, legacy, round-launcher, and Google Play assets with resource XML
• A multi-resolution Windows ICO plus Store, tile, splash, target-size, scale-factor, and MSIX visual assets
• A website favicon ICO, browser PNGs, Apple touch icon, and ready-to-paste HTML
