FAQPage Schema
How do I combine multiple images into a single AI-generated composite?▼

To combine multiple images into an AI-generated composite, provide 2 to 8 image URLs along with a concise prompt describing your desired scene. The tool encodes inputs to base64 and interfaces with Gemini 2.5 to generate the final merged visual.

Can I use this for face swapping and background replacement?▼

Yes, face swapping and background replacement are core features. You can seamlessly transplant faces between images or blend and swap backgrounds to create unified scenes for photography and marketing projects.

What is the maximum number of images I can merge for a multi-image collage?▼

You can merge a maximum of 8 images for a multi-image collage. The tool accepts 2 to 8 source images and processes them together to generate a cohesive single output.

Do I need an OpenRouter API key to generate thumbnails and collages?▼

Yes, an OpenRouter API key is required. The tool interfaces with OpenRouter Gemini 2.5 via a REST API to process your base64 encoded images and generate the composite thumbnail or collage.

How can I reduce API costs when creating AI image composites?▼

You can reduce API costs by using the optional image resizing feature before encoding. Resizing images lowers the data payload sent to the OpenRouter Gemini 2.5 API, which decreases processing expenses.

Are there limitations when merging images with AI for creative projects?▼

Limitations include a strict minimum of 2 and maximum of 8 source images per composite. Additionally, users must supply direct image URLs for base64 encoding, and complex prompts may incur higher OpenRouter API costs.
