A Figma plugin: design one ad, get every other size, plus linked language versions. Part of the Figma Toolkit.
Still in development. This tool is being built and tested, and its output can be wrong: a cropped face, text that doesn't fit, a missing layer. Check every generated size by eye against the design before you use, export or hand anything off. The automated checks help, but they don't replace your review. Provided as is.
