How to use Claude to resize images as a skill

People search this exact question. Here is the shortest path: free browser tool → copy-paste skill → optional MCP so Claude resizes images in chat.

Path A — 60 seconds (no install)

Path B — Claude skill pack (recommended)

1. Download /skills/resize-images/SKILL.md or copy it from the skills hub.
2. Add it to Claude project instructions, Claude skills, or your agent system prompt.
3. In chat: “Resize product.jpg to 1200px wide as WebP.”
4. Claude uses the documented API contract and returns a temporary download URL.

curl -F "image=@product.jpg" -F "width=1200" -F "format=webp" \
  https://agentmediatools.com/api/resize-image

Response includes success, dimensions, and downloadUrl.

Path C — MCP for Claude Desktop / Claude Code

1. Create a free account and API key via First win.
2. Install the Agent Media Tools MCP connection (see MCP setup guide).
3. Ask Claude: “Resize this image to 800px wide.” — it calls resize_image.
