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).

# Grayscale PDF
|
|
|
|
Convert all colors in a PDF to grayscale, producing a black-and-white version of the document.
|
|
|
|
## API Endpoint
|
|
|
|
`POST /api/v1/tools/pdf/grayscale-pdf`
|
|
|
|
Accepts multipart form data with a PDF file. No `settings` field is required.
|
|
|
|
## Parameters
|

This tool has no settings parameters. Upload the PDF file directly.
|
|
|
|
## Example Request

curl -X POST http://localhost:1349/api/v1/tools/pdf/grayscale-pdf \
|
|
-H "Authorization: Bearer si_your-api-key" \
|
|
-F "file=@document.pdf"
|
|
```
|
|
|
|
## Example Response
|
|
|
|
```json
|
|
{
|
|
"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
|
|
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/document.pdf",
|
|
"originalSize": 3200000,
|
|
"processedSize": 2800000
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- All color spaces (RGB, CMYK) are converted to grayscale, including embedded images, vector graphics, and text.
|
|
- The output file is often smaller than the original because grayscale data requires fewer bytes per pixel.
