DMG Canvas

DMG Canvas provides a visual editor for creating macOS disk images (.dmg files). Users arrange files by drag‑and‑drop, set a background image, add stylized text, and preview the layout exactly as it will appear in Finder, including Light and Dark mode variations. The tool also embeds license agreements, supporting styled, multilingual text without requiring manual configuration.

The application can rebuild the same image with a single click, and a built‑in command‑line utility enables integration into automated build pipelines. It supports legacy compatibility back to OS X 10.4 as well as modern compression and file‑system options such as LZMA and APFS, and automatically generates Retina‑ready assets for high‑resolution displays.

Targeted at macOS developers and distributors who need professionally styled installer images, DMG Canvas streamlines the design, licensing, and signing steps required to produce polished, ready‑to‑ship disk images.
