## What You Can Do With Stable Diffusion Online

The workflows people search for most - text-to-image, img2img, and inpainting - all wired into the same browser playground.

### Text-to-Image

Generate an image from a single text prompt.
Describe the subject, style, lighting, and framing - the playground turns it into a finished image in seconds, with no install and no GPU.

### Image-to-Image

Use an existing image as a visual anchor while your prompt pushes the output toward a new style, composition, or subject.
Ideal when text-only prompting is too loose for the look you want.

### Inpainting

Replace or remove parts of an image while keeping the rest intact.
Mask a region, write a prompt for the new content, and the playground fills the masked area to match the rest of the image.

### Prompt Generator

Build prompts by subject, medium, lighting, camera, style, and negative prompt - the structure that consistently produces strong results without prompt-spam guessing.

## A Workflow That Repeats

Four steps that turn a vague idea into an image you can actually ship.

### 1. Start With Intent

Describe subject, style, lighting, framing, and the things you do NOT want. The model responds to specificity - a sharper prompt produces a more usable first generation.

### 2. Tune The Settings

Pick an aspect ratio that matches your scene, raise the step count when you need fine detail, and add a negative prompt to steer the model away from artifacts you keep seeing.

### 3. Refine With Image-to-Image

When text-only prompting drifts, hand the model a reference image. Image-to-image keeps the composition you like and lets the prompt move structure and style around it.

### 4. Save What Worked

The prompts that produced your best images become repeatable templates. Tweak by scene and subject; keep the structure that got you there.

## Frequently Asked Questions

The questions people search for most before they try Stable Diffusion online - covering models, prompts, parameters, licensing, and privacy.

### What is Stable Diffusion?

Stable Diffusion is an open-source text-to-image diffusion model that turns natural-language prompts into photorealistic, stylized, or illustrative images. This playground runs it in the browser, so you don't have to install local checkpoints, set up a WebUI, or manage GPU dependencies.

### Can I use Stable Diffusion online for free?

Yes. Every visitor gets a free starting balance for Stable Diffusion text-to-image and image-to-image runs. Credit packs and monthly or yearly plans cover higher-volume generation when you need it - credits on one-time packs never expire.

### Do I need to install anything to use Stable Diffusion?

No. The playground runs Stable Diffusion server-side and streams the result back to your browser. You can generate, refine, and inpaint without installing it locally - no AUTOMATIC1111, ComfyUI, or GPU drivers.

### How does image-to-image differ from text-to-image in Stable Diffusion?

Text-to-image generates a Stable Diffusion image from a prompt alone. Image-to-image uses an existing image as a visual anchor while the prompt pushes the output toward a new style, composition, or subject - useful when prompt-only is too loose for the look you want.

### What is inpainting in Stable Diffusion?

Inpainting lets you mask a region of an image and have Stable Diffusion fill that region from a new prompt while leaving the rest of the image untouched. It's the standard workflow for replacing objects, removing artifacts, or refining specific parts of a generation.

### What's the difference between Stable Diffusion 1.5 and SDXL?

Stable Diffusion 1.5 runs at a 512x512 native resolution and is fast and lightweight. SDXL uses a much larger UNet and dual text encoders for sharper 1024x1024 output and better composition. Pick by use case: speed and stylization -> SD 1.5, balanced quality -> SDXL.

### How do I write a good Stable Diffusion prompt?

Structure your Stable Diffusion prompt by subject, medium, lighting, camera, style, and negative prompt. Specificity beats keyword-spam - naming the lens, time of day, or art reference typically produces a stronger result than a long flat tag list. The prompt guide page walks through reusable templates.

### What is a negative prompt, and when should I use one?

A negative prompt tells Stable Diffusion what you do not want in the image - common entries are 'blurry, deformed, extra fingers, low quality, watermark, text'. Negative prompts are one of the highest-leverage fixes when generations look off: instead of rewording the positive prompt, exclude the failure mode directly.

### What is CFG scale (guidance scale) in Stable Diffusion?

CFG scale (Classifier-Free Guidance) controls how strictly Stable Diffusion follows your prompt. Low values (3-5) leave the model more creative freedom; higher values (8-12) force tighter prompt adherence at the cost of artifacts. A value around 7 is the safe default - start there and adjust if the result drifts from your intent or looks overcooked.

### What is denoising strength in image-to-image?

Denoising strength (0-1) controls how much Stable Diffusion is allowed to alter the input image during image-to-image. At 0.2-0.4 the output stays very close to the source - good for style nudges; at 0.6-0.8 the prompt takes over and the source mostly anchors composition; at 1.0 it behaves like text-to-image. Match the value to how much of the original you want to keep.

### Can I use Stable Diffusion images commercially?

Stable Diffusion's open-source license permits commercial use of the images you generate. You're responsible for following our terms (no impersonation, no IP infringement, no disallowed content) and the upstream model license for the specific checkpoint you used. When in doubt, treat the output like any other asset you commission - keep your prompts and seeds so you can show provenance.

### Are my Stable Diffusion generations private?

Yes. Your generations are scoped to your account by default - they're not posted to a public feed, and other users can't browse them. Prompts and outputs are stored so you can revisit your history; you can delete them at any time from the playground.

### How do credits work, and do they expire?

Each generation deducts credits based on the model and resolution. Credit packs are one-time purchases that never expire. Monthly and yearly plans grant a credits allowance that refreshes on each renewal - unused allowance does not roll over. Failed generations don't consume credits.

### Why does my Stable Diffusion image look blurry, deformed, or generic?

Three quick fixes cover most cases: (1) add a negative prompt - 'blurry, deformed, low quality, extra limbs' clears the common failure modes; (2) raise the CFG scale toward 7-10 if the result is ignoring your prompt; (3) lower the denoising strength in image-to-image if the source identity is being lost. If the subject itself is rendered poorly, switch from SD 1.5 to SDXL.

### Can I use what Run Stable Diffusion Online makes commercially?

Every paid plan includes a commercial licence for what Run Stable Diffusion Online makes; the free tier is for personal use.
