Free Image Background Remover API

A production-grade REST API that removes the background from any image and returns a clean transparent PNG — completely free for your first 500 images. One HTTP call, no credit card required, results in under 3 seconds. After your free tier, pay just $0.0025 per image — the lowest verified price among major background removal APIs, 8× cheaper than Photoroom.

Quick start — free image background removal in one API call

Sign up, copy your key from the dashboard, and POST your image. The endpoint returns a generation id; poll until status=completed, then download the transparent PNG. Your first 500 calls are free — no card, no trial period, no expiry.

# Step 1 — submit the image (free for first 500 requests)
curl -X POST https://api.pixelapi.dev/v1/image/remove-background \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]"
# Response: {"generation_id": "uuid", "status": "queued", ...}

# Step 2 — poll until completed
curl https://api.pixelapi.dev/v1/image/UUID \
  -H "Authorization: Bearer YOUR_API_KEY"
# Response: {"status": "completed", "output_url": "https://..."}

Rate limits & error handling

The free tier allows 60 requests per minute. Exceeding the limit returns HTTP 429 with a Retry-After header. Recommended pattern: exponential backoff starting at 2 seconds, doubling on each retry up to 30 seconds maximum. The Python and Node SDKs handle this automatically.

# Python SDK auto-retries 429 with exponential backoff
from pixelapi import PixelAPI
client = PixelAPI(api_key="...", max_retries=4)
result = client.remove_background(image="product.jpg") # retries silently on 429
