Automate Background Removal Like a Pro with PixelAPI

Remove backgrounds from images in seconds — no Photoshop skills required

The Problem: Background Removal Without the Hassle

Ever needed to remove a background from an image for e-commerce, social media, or design projects — but didn't want to manually edit each one in Photoshop or Figma?

• Manual tools (like Photoshop) are slow for bulk processing
• Open-source models (e.g., U²-Net) require GPU setups and complex code
• Paid services (like Remove.bg) work but can get expensive at scale

That's where PixelAPI comes in — a fast, affordable API that lets you remove backgrounds (or generate custom ones) in seconds.

1. Setup: Get PixelAPI Working

Option A: Python (Recommended for Automation)

pip install requests

Save your API key from PixelAPI's dashboard as an environment variable:

export PIXELAPI_KEY="your_api_key_here"  # Linux/Mac

Option B: curl (Quick CLI Testing)

curl -X POST https://api.pixelapi.dev/v1/image/generate \
  -H "X-API-KEY: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"model": "sdxl", "prompt": "white background"}'

2. Basic Background Removal

Python Example

import requests
import os

API_KEY = os.getenv("PIXELAPI_KEY")
IMAGE_URL = "https://example.com/your-image.jpg"

response = requests.post(
    "https://api.pixelapi.dev/v1/image/remove-bg",
    headers={"X-API-KEY": API_KEY},
    json={"image_url": IMAGE_URL}
)

if response.status_code == 200:
    with open("output.png", "wb") as f:
        f.write(response.content)
    print("✅ Background removed! Saved as 'output.png'")
else:
    print(f"❌ Error: {response.text}")

curl Example

curl -X POST https://api.pixelapi.dev/v1/image/remove-bg \
  -H "X-API-KEY: your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"image_url": "https://example.com/your-image.jpg"}' \
  --output output.png

3. Custom Background Generation

Want a white, gradient, or branded background instead of transparency? PixelAPI supports prompt-based generation.

response = requests.post(
    "https://api.pixelapi.dev/v1/image/generate",
    headers={"X-API-KEY": API_KEY},
    json={
        "image_url": IMAGE_URL,
        "model": "sdxl",
        "prompt": "professional product photo, white background, 8k"
    }
)

if response.status_code == 200:
    with open("product_white_bg.png", "wb") as f:
        f.write(response.content)
    print("✅ Custom background generated!")

4. Batch Processing (Multiple Images)

image_urls = [
    "https://example.com/product1.jpg",
    "https://example.com/product2.jpg",
]

for i, url in enumerate(image_urls, 1):
    response = requests.post(
        "https://api.pixelapi.dev/v1/image/remove-bg",
        headers={"X-API-KEY": API_KEY},
        json={"image_url": url}
    )

    if response.status_code == 200:
        with open(f"output_{i}.png", "wb") as f:
            f.write(response.content)
        print(f"✅ Processed {url}")
    else:
        print(f"❌ Failed {url}: {response.text}")

5. Error Handling & Best Practices

try:
    response = requests.post(
        "https://api.pixelapi.dev/v1/image/remove-bg",
        headers={"X-API-KEY": API_KEY},
        json={"image_url": "invalid-url"},
        timeout=10
    )
    response.raise_for_status()
    print("Success!")
except requests.exceptions.HTTPError as err:
    print(f"HTTP Error: {err}")
except requests.exceptions.RequestException as err:
    print(f"Request Failed: {err}")

load_dotenv()
API_KEY = os.getenv("PIXELAPI_KEY")
INPUT_DIR = "input_images/"

    """Remove BG or generate custom background."""
    endpoint = "remove-bg" if not prompt else "generate"
    payload = {"image_url": image_url}
    if prompt:
        payload.update({"model": "sdxl", "prompt": prompt})

    try:
        response = requests.post(
            f"https://api.pixelapi.dev/v1/image/{endpoint}",
            headers={"X-API-KEY": API_KEY},
            json=payload,
            timeout=15
        )
        response.raise_for_status()

        print(f"✅ {output_filename} processed!")
        return True
    except Exception as e:
        print(f"❌ Failed {output_filename}: {e}")
        return False

if __name__ == "__main__":
    for filename in os.listdir(INPUT_DIR):
        if filename.lower().endswith(('.png', '.jpg', '.jpeg')):
            image_url = f"file://{os.path.join(INPUT_DIR, filename)}"
            process_image(image_url, filename.replace(".jpg", "_bg_removed.png"))
            process_image(
                image_url,
                filename.replace(".jpg", "_white_bg.png"),
                prompt="clean white background, no shadows"
            )
            time.sleep(0.5)
