Free macOS Icon Toolkit

API docs

Generate, prepare, and export production-ready app icons without installing specialist software. Apply the standard macOS squircle and shadow, create icons with AI, remove backgrounds, or convert artwork into macOS ICNS, Windows ICO and MSIX, Linux hicolor, favicon, Icon Composer, and Xcode app icon formats. Every tool below is also a live endpoint of the API docs. Sign in to run a tool with your personal API allowance; toolkit runs and public API calls share the same monthly limits.

Icon mask

1 mask per run

Trims your artwork, refits it inside the standard squircle content box, clips it to the app-icon mask and paints the macOS drop shadow — or composites it as an emblem on the macOS folder icon.

Choose Your Source

PNG, JPEG, WebP, or SVG artwork works best.

Fit artwork to mask

Turn off to preserve the submitted pixel size and simply clip the artwork.

Drop shadow

Apps shadow the mask; folders shadow the artwork’s non-transparent pixels.

Use artwork’s dominant color

Overrides the background with the artwork’s most prominent color.

Artwork scale

Scales around the artwork center, keeping it centered when offsets are zero.

Horizontal position

Offset from center; positive moves right.

Vertical position

Offset from center; positive moves down.

Position unit

The unit of the position values.

Background

Fill behind the artwork, inside the squircle.
