Inpainting technology, powered by [Stable Diffusion](/aisha_kapoor_d69b3a75/ai-image-generators-2026-vheer-visualgpt-fooocus-comfyui-midjourney-more-compared-2i44), opens up new horizons for image repair and modification. This innovative method uses the context of intact image segments to reconstruct altered or incomplete parts, simplifying defect removal and image customization.

## Getting Started with Fooocus Inpainting {#getting-started}

### Activating Inpainting in Fooocus

![Inpainting in Fooocus](https://promptzone-community.s3.amazonaws.com/uploads/articles/6gjwv8rjld4i9kxxb5px.png)

1. Check the "Input Image" box below the Prompt field
2. Open the "Inpaint or Outpaint" tab

**Note:** When active, the Generate button performs inpainting based on the uploaded image and specified options, while still considering the main prompt.

If you don't have it locally you can still use it in a google colab [here](https://colab.research.google.com/github/lllyasviel/[Fooocus](/jaroslav/how-to-use-fooocus-a-practical-guide-and-tricks-3hfk)/blob/main/fooocus_colab.ipynb)

## Inpainting Techniques in Fooocus {#techniques}

### 1. Completing an Image

Perfect for restoring damaged photos:

1. Upload the image
2. Define the inpainting mask using the drawing tool
3. Write a prompt describing the desired outcome
4. Click Generate

### 2. Enhancing Details

Ideal for improving specific areas like faces or hands:

![restoring damaged photos](https://promptzone-community.s3.amazonaws.com/uploads/articles/526x1qxn5qn1tyhsuvfa.png)

1. Upload the image
2. Draw a mask over the area to enhance
3. Select "Improve Detail" as the Method
4. Provide a complementary prompt for the area
5. Generate and repeat for other areas if needed

### 3. Adding Elements

Transform your image by adding new objects or details:

![Modify Content image](https://promptzone-community.s3.amazonaws.com/uploads/articles/rbv8x13dr2k4hzd3s16s.png)

1. Upload the image
2. Draw a mask where you want to add the new element
3. Choose "Modify Content" as the Method
4. Write a prompt describing the new element
5. Generate and repeat to add multiple elements

## Advanced Inpainting Options {#advanced}

For experienced users, Fooocus offers advanced configuration options:

![example impainting](https://promptzone-community.s3.amazonaws.com/uploads/articles/8c25smkju5xniuzhdsyx.png)

1. Check the "Advanced" box next to "Input Image"
2. Open the "Advanced" tab
3. Enable "Developer Debug Mode"
4. Access the "Inpainting" tab for detailed options

### Key Advanced Parameters:

- **Debug Inpaint Preprocessing:** Visualize the pre-processing steps
- **Disable initial latent in inpaint:** Toggle consideration of content outside the mask
- **Inpaint Engine:** Select the model version
- **Inpaint Denoising Strength:** Control the influence of the original image
- **Inpaint Respective Field:** Adjust the size of the generated inpainting area
- **Mask Erode or Dilate:** Modify mask edges
- **Enable Mask Upload:** Use a custom mask image
- **Invert Mask:** Reverse the mask effect

## Combining Inpainting with Image Prompt {#image-prompt}

Unlock the power of style transfer and composition guidance:

1. Access the "Advanced" panel
2. Enable "Developer Debug Mode"
3. Open the "Control" tab
4. Check "Mixing Image Prompt and Inpaint"

This feature allows simultaneous use of Image Prompt and Inpainting, perfect for face swaps or background style changes while preserving subjects.

## Conclusion {#conclusion}

Fooocus Inpainting opens up a world of possibilities for image manipulation and creation. With different techniques, combine features, to create stunning images.
## Choosing the Right Method {#choosing-method}

The Method dropdown is the single setting that most often decides whether a result works,
and picking the wrong one is the most common reason inpainting "does nothing".

| Method | Use it when | What it does |
| --- | --- | --- |
| **Improve Detail** | Faces, hands, eyes, text, small textures | Refines what is already inside the mask, keeping composition |
| **Modify Content** | Adding or replacing an object | Generates new content from your prompt inside the mask |
| **Remove Object** | Deleting something | Fills the mask from surrounding context, ignoring the prompt |

If you mask a region, write a prompt describing something new, and get back a subtly cleaner
version of the original, you are on Improve Detail and want Modify Content.

## Denoising Strength in Practice {#denoise}

Inpaint Denoising Strength controls how much of the original pixels survive. It is the
second setting worth learning properly:

- **0.2–0.4** — light touch-ups, texture and blemish cleanup, keeps the original almost intact
- **0.5–0.7** — the useful middle ground for detail work on faces and hands
- **0.8–1.0** — effectively regenerates the masked region; required when adding an object,
  but it will ignore what was there before

Start in the middle and move in one direction. Large jumps make it hard to tell which change
caused which result.

## Fixing Common Inpainting Problems {#troubleshooting}

**Visible seam around the edited region** — the mask boundary is landing on detail. Grow the
mask slightly with Mask Erode or Dilate so the transition falls on flat area rather than an
edge, and avoid tracing tightly around the subject.

**The new element does not match the lighting** — inpainting only sees the masked region and
its immediate surroundings. Describe the lighting explicitly in the prompt ("lit from the
left, warm evening light") rather than expecting it to be inferred.

**Faces come back distorted** — the masked area is too small for the model to resolve a
coherent face. Widen the mask to include the whole head, and increase Inpaint Respective
Field so more context is considered.

**The object will not disappear** — Remove Object needs clean surroundings to sample from. If
the object touches a busy edge, remove it in two passes, working from the simpler side.

**Results change wildly between runs** — this is expected at high denoise. Lower the strength
or fix the seed so you are comparing like with like while you tune.

## FAQ {#faq}

### Why does the Generate button do nothing after I upload an image?
The "Input Image" checkbox below the prompt has to be ticked and the "Inpaint or Outpaint"
tab selected. Without both, Fooocus runs an ordinary text-to-image generation.

### Do I still need a prompt when inpainting?
For Improve Detail and Modify Content, yes — describe what should be in the masked area, not
the whole picture. For Remove Object the prompt is ignored.

### Can I use my own mask instead of drawing one?
Yes. Enable Developer Debug Mode, open the Inpainting tab and turn on Enable Mask Upload.
Invert Mask flips which side is treated as the region to change.

### Which inpaint engine version should I use?
Newer engine versions generally blend better at mask edges. If an older workflow suddenly
produces worse seams after an update, the engine version is the first setting to check.

### Can I inpaint and use an image prompt at the same time?
Yes — enable Developer Debug Mode, open the Control tab and tick "Mixing Image Prompt and
Inpaint". This is the route for style transfer or face swaps that preserve the subject.
