What img2img tools do
Img2img (image-to-image) tools take a picture you already have and a short text prompt, then produce a new image that follows the original's composition while changing style, background, lighting or subject details. The source image acts as a reference, which is why people also search for an image generator using a reference image. The result stays closer to what you intended than a prompt alone would.
The tools here are used by designers testing visual directions, marketers reworking product photos, creators restyling portraits and hobbyists who want to remix a snapshot. They replace a good deal of manual retouching and masking in a traditional editor, and they replace the trial and error of describing a composition in words when text-to-image generation keeps missing the layout.
All eight listed tools run in the browser as web apps, so nothing needs installing. Most pair a free allowance with paid credits or a subscription.
How to choose an img2img tool
Start with cost, since many readers look for a free img2img option. Check what the free tier actually includes: daily credits, a one-time trial or a capped number of generations. Then see whether paid use is credit-based or a subscription, because that decides how the cost scales with heavy use.
Next, consider how faithful the output needs to be. Some tools stress keeping the original image intact while editing with a prompt, which suits photo touch-ups. Others lean toward bigger restyling, which suits creative exploration.
Model choice matters too. A studio with several models in one place lets you compare results from the same reference without switching sites. Finally, think about the job: headshots, background swaps and restyling are specific tasks, and a tool built around one of them can beat a general one. Multilingual prompt support helps if English is not your working language.

Common questions
What is img2img?
Img2img is a method where an AI model starts from an input image instead of from nothing. A text prompt describes the change, and the model produces a new picture that keeps much of the source's structure. It is used for restyling, editing and variations.
Is there a free img2img tool?
Several tools on this page are Freemium, so you can try them without paying. Free access usually means limited credits or a trial, and heavier use moves to paid credits or a subscription. Check the allowance before committing a project to one.
Can I generate images from a reference image?
Yes, that is the core purpose of this category. Upload the reference, write a prompt describing the change and adjust until the result fits. Results vary by model, so trying the same reference in a multi-model tool is a practical way to compare.
When to look elsewhere
If your starting point is a rough sketch rather than a photo, Drawing to Image tools are built for that input. If you want results that update as you type, Realtime Image Generator is the closer fit. Both sit under the same Image Generator hub as this page.
