Resize a design

Resize a design

Starts a job that creates a resized copy of a design at a preset design type or a custom width and height.

Note: Needs a user on a plan with premium features, such as Canva Pro; Free users get a limited trial. Canva docs, emails and Canva Code designs can't be resized.

Set up

Use the first option your agent supports.

MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

{ "mcpServers": { "canva": { "url": "https://mcp.canva.com/mcp" } } }

Call the MCP tool resize-design.

Server URL: https://mcp.canva.com/mcp

API (official)

• Base URL: https://api.canva.com/rest/v1
• Endpoint: POST /resizes
• Auth: an OAuth access token, sent as Authorization: Bearer <token>
• Docs: https://www.canva.dev/docs/apps/rest-apis/

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
