What is a image editing API?

Image editing (image-to-image) sends an existing picture and a text instruction and gets back a modified picture. It is how product-photo pipelines, avatar tools and ad-creative generators work; prompt adherence on the untouched regions is the quality bar.

How to choose

Product photo and e-commerce

GPT Image 2 and Nano Banana Pro keep the product pixel-accurate while changing scene and light.

Style transfer and restyling

Seedream 5 and Qwen Image 2 for illustration, poster and brand-style conversions.

Text in images

GPT Image 2 renders and corrects text most reliably.

Batch variations

Nano Banana 2 for cheap variants once a hero image is approved.
