Move all 157 tool pages into image/video/audio/pdf/data subfolders so URLs read /tools/<modality>/<id> (e.g. /tools/image/crop). Nest the image sub-categories under an Image group in the sidebar so the nav reads by modality. Add public/_redirects (301, clean + .html forms) mapping every old flat /tools/<id> URL to its new path so inbound links keep working. Rewrite all internal /tools links. Verified with a clean docs build (no dead links).

# Blur Background
|
|
|
|
Blur the background of an image while keeping the subject sharp. The AI model isolates the subject, applies a blur to the original background, and composites the sharp subject on top.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/image/blur-background`
|
|
|
|
Accepts multipart form data with an image file and a JSON `settings` field.
|
|
|
|
## Parameters
|
|
|
|
| Parameter | Type | Required | Default | Description |
|
|
|-----------|------|----------|---------|-------------|
|
|
| intensity | integer | No | `50` | Blur intensity (1-100) |
|
|
| feather | integer | No | `0` | Edge feathering radius (0-20) |
|
|
| format | string | No | `"png"` | Output format: `png` or `webp` |
|
|
|
|
## Example Request
|
|
|
|
```bash
|
|
curl -X POST http://localhost:1349/api/v1/tools/image/blur-background \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@photo.jpg" \
|
|
-F 'settings={"intensity": 75, "feather": 3}'
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"async": true
|
|
}
|
|
```
|
|
|
|
Track progress via SSE at `GET /api/v1/jobs/{jobId}/progress`. When the job completes, the SSE stream emits a `completed` event with the download URL.
|
|
|
|
## Notes
|
|
|
|
- This is an AI-powered tool that returns `202 Accepted` and processes asynchronously. Connect to the SSE endpoint to receive progress updates and the final result.
|
|
- Requires the **background-removal** feature bundle to be installed. Returns `501` if the bundle is not available.
|
|
- Higher intensity values produce a stronger blur effect. Values above 80 create a pronounced bokeh-like separation.
|
|
- HEIC, RAW, PSD, and SVG inputs are automatically decoded before processing.
