# Background Removal

### How It Works

1. **Attach an image** - Upload or drag & drop the image
2. **Request background removal** - Type "remove background" or use natural language
3. **AI processes** - System automatically detects intent and routes to background removal
4. **Get result** - Receive transparent PNG with background removed

### Two Methods

#### Automatic Background Removal

**Best for:** Simple backgrounds, clear subjects

1. **Attach image**
2. **Type:** "Remove the background" or "Make background transparent"
3. **AI automatically detects** and processes
4. **Get transparent PNG**

**How it works:**

* Uses the Bria AI model
* Automatically detects the subject
* Removes background cleanly
* Outputs transparent PNG

#### Subject-Specific Removal

**Best for:** Complex scenes, multiple subjects, specific selection

1. **Attach image**
2. **Type:** "Remove background, keep the \[subject]" or "Isolate the \[object]"
3. **AI uses a prompt** to identify what to keep
4. **Get the result** with the specified subject isolated

**How it works:**

* Uses EVF-SAM model
* Uses your prompt to identify the subject
* More precise control
* Better for complex scenes

### Use Cases

#### Product Photography

**Example:**

* Upload product photo
* Request: "Remove background."
* Result: Product on transparent background
* Use: E-commerce, catalogs, marketing

#### Portrait Isolation

**Example:**

* Upload a portrait photo
* Request: "Remove background, keep the person."
* Result: Person on transparent background
* Use: Headshots, profile pictures, composites

#### Object Extraction

**Example:**

* Upload an image with multiple objects
* Request: "Remove background, keep the car."
* Result: Car isolated on a transparent background
* Use: Graphics, design work, composites

#### Background Replacement

**Example:**

* Upload image
* Request: "Remove background and replace with \[new scene]."
* Result: Subject on a new background
* Use: Creative composites, scene changes

### Tips for Best Results

1. **Clear subject** - Well-defined subjects work best
2. **Good contrast** - Subject should stand out from the background
3. **High quality** - Better source images = better results
4. **Be specific** - For complex scenes, specify what to keep
5. **Simple backgrounds** - Works best with uncluttered backgrounds
6. **Good lighting** - Well-lit subjects produce cleaner edges

### Output Format

#### Transparent PNG

**Characteristics:**

* **Format:** PNG with alpha channel
* **Transparency:** Background is fully transparent
* **Quality:** Maintains original image quality
* **Compatibility:** Works in all design software

**Use cases:**

* Design work
* Composites
* Graphics
* Web use

### Common Workflows

#### Quick Background Removal

1. Upload image
2. Type: "Remove background"
3. Get transparent PNG
4. Use in your project

#### Subject Isolation

1. Upload image
2. Type: "Remove background, keep the \[subject]"
3. Get an isolated subject
4. Composite into the new scene

### Troubleshooting

#### "Background not fully removed."

**Solutions:**

* Ensure good contrast between the subject and the background
* Try subject-specific removal with a clear prompt
* Check image quality (higher quality = better results)
* Request refinement: "Remove more of the background."

#### "Subject edges are rough."

**Solutions:**

* Use higher-quality source images
* Ensure good lighting in the original
* Try different models (subject-specific may be better)
* Request edge refinement

#### "Wrong subject isolated."

**Solutions:**

* Be more specific in your prompt
* Use a subject-specific removal method
* Describe the subject clearly
* Try: "Keep only the \[specific subject]."

#### "Background removal not working."

**Solutions:**

* Check that the image is properly attached
* Ensure you're requesting background removal clearly
* Try: "Remove background" or "Make transparent."
* Verify API keys are configured

{% hint style="info" %}
**Need to remove a background from video (not an image)?** Background Removal works on still images only. For video, use [SAM 3 Rotoscoping](/features/video-editing-tools/sam-3-rotoscoping.md) — it isolates a moving subject frame-by-frame and outputs a transparent-background MOV ready for Premiere Pro compositing.
{% endhint %}

**Next:** Learn about [Image Upscaling](/features/image-generation/image-upscaling.md) for increasing image resolution.\
