# Flux Kontext Pro Image Generator

Generate from text or guide a change with one reference image, a required prompt, six aspect ratios and one to four outputs.

> Canonical: https://stable-diffusion-web.com/flux-kontext

Flux Kontext Pro supports prompt-only generation and single-image guidance, with six framing choices, one-to-four outputs and paid-model access.

## Flux Kontext Pro prompt and reference examples

Six example directions covering restyling, object changes, backgrounds, recurring subjects, clothing and text-bearing layouts. Outputs are examples, not guarantees.

### Style Transfer

### Object Swap

### Background Change

### Character Across Scenes

### Outfit Edit

### Text Edit

## What Controls Does Flux Kontext Pro Expose?

The executable form—not general model descriptions—defines what can be submitted and what users should verify before accepting an output.

### Text and Reference Modes

Start from a prompt alone or add one source image. The reference workflow guides a change; it does not guarantee that unspecified regions remain identical.

### One Required Reference Image

Reference mode accepts one JPEG, PNG or WebP file up to 10 MB. A valid transport-backed image is required before the edit can be submitted.

### A Required 3,000-Character Prompt

Describe the intended result in a prompt of up to 3,000 characters. Name protected details explicitly and avoid assuming the model understands unstated constraints.

### Six Aspect Ratios

Choose 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16. The selected ratio controls framing but does not guarantee composition or edge detail.

### One to Four Outputs

Request one, two, three or four independently billed results. Review the total debit shown by the generator before submitting a batch.

### Paid Access and Estimated Turnaround

This is a paid-access model. The form lists an estimate of about one minute, but queue and request conditions can change actual completion time.

## Flux Kontext Pro use cases and editing limits

Use these as qualified starting points for prompt-only or reference-guided work. Each result still needs comparison against the brief and source.

### Reference-Guided Photo Changes

Describe a background, object, lighting or styling change and verify both the requested edit and any unintended changes elsewhere.

### Recurring Subject Exploration

Reuse the same source while varying scene or framing, then compare identity, proportions and distinctive details across every result.

### Creative Restyling

Ask for a new visual treatment while naming composition or subject details that must remain recognizable.

### Product Concept Variants

Explore colors, settings or seasonal treatments from a product image, then check shape, labels and packaging against the original.

### Marketing Variations

Generate alternative scenes or layouts for a campaign and route selected results through the normal brand and compliance review.

### Text-Bearing Image Drafts

Prompt for signs, posters or labels as drafts only; inspect spelling, letter shapes and layout before using the image publicly.

## What a run costs and returns

## Generation and Editing Questions

Direct answers about input modes, file limits, framing, batch size, paid access, timing, rights and output variability.

### What is Flux Kontext Pro?

Flux Kontext Pro is a selectable image model in this app with prompt-only and single-reference workflows, six aspect ratios and one-to-four output batches.

### Can I generate without uploading an image?

Yes. Text mode requires a prompt and no source image. Reference mode requires one valid image plus a prompt describing the intended result.

### Which reference files are accepted?

Reference mode accepts one JPEG, PNG or WebP file up to 10 MB. Additional source images are not accepted by this form.

### Is paid access required?

Paid-model access and sufficient credits are required. The form shows the current debit before the request is submitted.

### How long should a request take?

The form lists an estimate of about one minute. Actual completion time varies with queue and request conditions.

### Which framing choices are available?

The form offers 21:9, 16:9, 4:3, 1:1, 3:4 and 9:16. It does not expose resolution, mask or layer controls.

### How do one-to-four outputs work?

Each selected output becomes an independently billed generation job. Increase the count only after checking the displayed total.

### Can generated images be used commercially?

Every paid plan includes this app's commercial license for generated work, subject to app terms and third-party rights in the source, prompt and output.

### Does a reference image guarantee an exact edit?

No. A source image and prompt guide the result, but identity, untouched regions, embedded text and product details can still drift and require review.

### How many credits does Flux Kontext Pro use?

Flux Kontext Pro draws 10 credits per run.

### What limits should I check before using Flux Kontext Pro?

Generated output from Flux Kontext Pro can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 10 MB each.

### What happens to the files I upload to Flux Kontext Pro?

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 Flux Kontext Pro makes commercially?

Every paid plan includes a commercial licence for what Flux Kontext Pro makes; the free tier is for personal use.
