Remove image backgrounds in Python
A common choice for image-processing scripts and data pipelines. The requests library handles the multipart upload with no extra setup.
Install (pip)
pip install requestsRemove a background
import requests
response = requests.post(
"https://api.bgbuster.com/images/remove-background",
headers={"X-Api-Key": "your-api-key"},
files={"input": open("photo.jpg", "rb")},
data={"format": "png"},
)
print(response.json()["url"])The request is a multipart POST to https://api.bgbuster.com/images/remove-background, authenticated with your API key in the X-Api-Key header. Pass the image as a file (input) or as a public URL string.
By default the response is JSON with a temporary download url. That URL stays valid for 24 hours — download and store the image yourself if you need it longer.
Need more than a plain removal? POST /images/edit takes the same kind of request and chains background removal together with resize, rotate, flip, blur, brightness/contrast/saturation, and trim — in whatever order you list them.
| Field | Type | Required | Description |
|---|---|---|---|
| input | File or string | Yes | Image file or a public URL to fetch it from. |
| output | "url" or "raw" | No | Return a temporary download URL, or the transformed image bytes directly. Defaults to "url". |
| format | "png" or "webp" | No | Output image format. Defaults to "png". |
| trim | boolean | No | Trim empty transparent space around the result. |
Default (output=url)
{
"id": "image-id",
"url": "https://..."
}With output=raw, save the image bytes directly instead of following a URL
