# AI Image Generator - Free Online Text-to-Image Tool

> Canonical: https://stable-diffusion-web.com/ai-image-generator

## AI Image Generator

A free AI image generator running entirely in your browser - prompt from scratch, restyle a reference, or inpaint a region.

## Who uses this AI image generator, and for what?

Designers, marketers, ecommerce teams, educators, and creators use these text-to-image, image-to-image, inpainting, and prompt workflows when they need a still image rather than motion.

### Text-to-Image AI

Generate images from text prompts. The AI image generator reads your description and produces a finished image in seconds - no install, no GPU.

### Image-to-Image AI

Drop a reference image and let the AI restyle or remix it. Great when text-only prompting is too loose for the look you want.

### AI Inpainting

Mask a region of an image and the AI generator fills it from a new prompt while the rest stays untouched. Standard for object replacement.

### Prompt Generator

Build sharp prompts with the structured prompt generator - subject, medium, lighting, camera, style, and negative prompt templates.

## A Workflow That Works With This AI Image Generator

This AI image generator rewards structured prompting over keyword spam. These four steps - prompt structure, model choice between the fast model and SDXL, negative prompts, and saving winners as templates - cover most cases and stay repeatable across projects.

### 1. Write a Structured Prompt

A good AI image starts with a structured prompt: subject first, then medium, lighting, camera, style. Specificity beats keyword spam.

### 2. Pick the Right Model

The fast model is the quickest in the lineup; SDXL is sharper at 1024×1024 with cleaner composition. Switch in the playground.

### 3. Add a Negative Prompt

Negative prompts ("blurry, deformed, low quality") tell the AI what NOT to generate. Highest-leverage fix for most output drift.

### 4. Save What Worked

Your best AI image prompts become repeatable templates. Keep the structure that produced a winner; tweak by subject and scene.

## AI Image Generator FAQ

Answers on cost, the fast model versus SDXL, signup and free credits, commercial use, watermarks, mobile, and how the browser generator compares to a local install.

### Is the AI image generator free?

Yes. Every new account starts with a free credit balance. Heavier usage moves to a credit pack or monthly/yearly plan; one-time credits never expire.

### Which AI model does the generator use?

A choice of models - a fast, stylized model and SDXL for sharper 1024×1024 output. Switch between them in the playground.

### Do I need to sign up to use the AI image generator?

Yes, a quick signup grants the free credit balance and keeps your generation history across sessions. Generations are scoped to your account.

### Can I use AI-generated images commercially?

Yes. The model license permits commercial use; you're responsible for following our terms and the upstream model license.

### How long does an AI image take to generate?

The fast model typically returns in under 15 seconds; SDXL in 20-40 seconds. Time depends on resolution and step count.

### Do AI-generated images have a watermark?

No watermark is applied. The images are yours to use under the upstream license and our terms.

### Can I run the AI image generator on my phone?

Yes. Generation runs server-side - the playground works in any modern mobile browser. Large reference uploads are easier on desktop or tablet.

### How is this AI image generator different from a local install?

The Stable Diffusion Web AI image generator avoids local GPU setup and model downloads, but its available models, controls, cost, privacy, speed, and output can differ from a local installation. Compare the current form with the local workflow you are considering.

### How many credits does AI Image Generator use?

AI Image Generator draws between 4 and 30 credits per run, depending on the model and length chosen in the form.

### What limits should I check before using AI Image Generator?

Generated output from AI Image Generator can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use.

### What happens to the files I upload to AI Image Generator?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what AI Image Generator makes commercially?

Every paid plan includes a commercial licence for what AI Image Generator makes; the free tier is for personal use.
