One of the main functionalities of IMG Processing is the background removal feature, being one of the best on the whole internet, in quality and price, being x50 cheaper than tools like RemoveBG, and getting awesome results. In this guide, we’ll see how to remove the background of an image using the API.

​
Creating an Image

All the images in IMG Processing, must be created. To create an image you can upload one from your computer, by an url from an allowed origin, or create one from a prompt. Let’s create an image by uploading one from your computer. We’ll use the curl command to do this since it’s the more generic way to do it, but you can use any other tool you want. First, download the image you want to remove the background from. Here we’ll use a cat image. Cat with background Then, copy your api key on the dashboard and replace it on the x-api-key field, and replace the image field with the path to the image you want to remove the background from. 
curl -X POST "https://api.img-processing.com/v1/images" \
     -H "x-api-key: YOUR_API_KEY" \
     -F "image=@cat2.png" \
     -F "name=cat-image"
After doing it, just run send! This will return an image object in the response. 
{
    "id":"image_iv7d1rish0ymrmk7qwuht3ap",
    "name":"cat-image",
    "url":null,
    "width":1024,
    "height":1024,
    "format":"png",
    "size":1427326,
    "created_at":"2025-04-01T16:15:44.212Z"
}
Now, we have the image created, and we can remove the background.

    "format":"png",
    "size":1217323,
    "created_at":"2025-04-01T16:21:49.596Z"
