This template integrates OpenAI's image generation and editing endpoints via the GPT-Image-1 model to visually create and manipulate images based on prompts. It features base64 conversion, binary handling, and prompt chaining.
Perfect for marketing, design, product visuals, and creative workflows.
Requirements
- OpenAI account with access to gpt-image-1 (probably you need organization verifications for access to that model)
- OpenAI API credentials configured in n8n
- A self-hosted or cloud n8n instance
- Basic familiarity with the n8n UI (no programming required)
Step-by-step InstructionsStep 1: Manual Trigger
Starts the workflow on click. Ideal for testing the generation and edit logic.
Step 2: Generate Image
The Create image call node sends a prompt to OpenAI and returns a base64 image.
Example prompt:A cyberpunk city at night with flying cars and neon lightsStep 3: Convert to Binary
The base64 image is converted into a usable binary PNG file with the Convert json binary to File node.
Step 4: Edit the Image
The binary file is passed to OpenAI’s /images/edits endpoint. A new prompt applies changes to the image.
Example:Add a glowing robot in the foreground with a neon sword
Supports model: gpt-image-1
Requires binary file (not base64)Step 5: Final Conversion
Converts the final edited image from base64 to file so it can be downloaded or used in other nodes.
Real-World Use Cases
Artists & Creators: concept art and illustration variations
E-commerce: auto-generate product mockups
Marketing: create eye-catching blog or social visuals
Bonus Ideas
- Add a Telegram or Slack node to generate or edit images via chat
- Use a Webhook to feed prompts from a form or frontend
- Add a mask to restrict edits to specific areas (e.g., background only)
