Tips
- Tip 1For Instagram's feed, 4:5 portrait (1080 × 1350) takes the most room on a phone.
- Tip 2Keep text and faces away from the edges of covers and banners: phones and computers crop them differently.
- Tip 3Use PNG for text and logos, JPG for photos.
Use it from an AI app
ChatGPT, Claude and other AI apps can run this too, through the free API or the free MCP server. No account or key needed.
