RemBG 배경 제거 API – 개발자 문서 및 통합 가이드

# Full example: upload an image and remove its background with all optional parameters
curl -X POST "https://api.rembg.com/rmbg"
  -H "x-api-key: YOUR_API_KEY_HERE"          # your personal API key
  -F "image=@/path/to/image.jpg"             # input image file
  -F "format=webp"                           # output format: webp (default) or png
  -F "w=800"                                 # target width in pixels (maintains aspect ratio unless exact_resize=true)
  -F "h=600"                                 # target height in pixels
  -F "exact_resize=false"                    # true = force exact w × h, may distort
  -F "mask=false"                            # true = return only the alpha mask instead of full image
  -F "bg_color=#ffffffff"                    # optional solid background color (RGBA hex)
  -F "angle=0"                               # rotate the image by given degrees after processing
  -F "expand=true"                           # add padding so rotated images don’t get cropped
