Use Six-IR in Claude and ChatGPT
Add the free Six-IR connector to your AI assistant, then just ask: "What size is a YouTube thumbnail?" or "Get my photo under 100 KB for my visa form." You get the exact pixels and a link that opens Six-IR already set up, so you only add your photo.
The connector address
https://six-ir.com/mcp
No API key and no account: paste the address and it works.

- In Claude, open Settings → Connectors.
- Press Add custom connector.
- Name it Six-IR and paste

Questions
Does the Six-IR connector cost anything?
No. The connector is free, needs no Six-IR account and no sign-in, and the resizer it links to is free too.
Does Claude or ChatGPT see my photo?
No. The connector only answers questions about sizes and makes links. Your photo is resized in your own browser when you open the link, and it is not uploaded.

Which platforms does it know?
Instagram, TikTok, YouTube, Facebook, LinkedIn, X (Twitter), Pinterest, Etsy, Amazon, Twitch, Discord, print at 300 dpi and websites, the same sizes as the size guides.
