What canva-resize-for-social-media does

The skill identifies a Canva design from its ID, link or name, then uses resize-design to make the requested versions. You can ask for all five supported formats or select specific ones: an Instagram post is 1080 × 1080, while an Instagram story is 1080 × 1920. Facebook and Instagram stories share dimensions but are made as separate designs.

The agent returns Canva editing links for the results. If one resize fails, it continues with the other selected formats and reports which succeeded. The current environment needs the Canva MCP resize-design tool; without it, the skill cannot resize the design.

What it helps with

  • create Facebook and Instagram post versions from one Canva design
  • prepare separate story designs for Facebook and Instagram
  • make a LinkedIn post version of an existing design
  • get Canva editing links for resized designs
