Remove.bg

Overview

Remove.bg removes backgrounds from images using AI — a single POST with an image returns a transparent-background PNG. Requires a free API key (verified: GET returns 404, POST with an invalid key returns 403 “API Key invalid”).

Quick Start

Remove background from an image URL (replace YOUR_KEY):

curl -X POST "https://api.remove.bg/v1.0/removebg" \
  -H "X-Api-Key: YOUR_KEY" \
  -d "image_url=https://example.com/photo.jpg&size=auto" \
  -o output.png

From a local file:

curl -X POST "https://api.remove.bg/v1.0/removebg" \
  -H "X-Api-Key: YOUR_KEY" \
  -F "image_file=@photo.jpg" \
  -o output.png

Authentication

• Register at remove.bg → free API key (in your dashboard).
• Send it as the X-Api-Key header (invalid key → 403 “API Key invalid”, verified).
• The endpoint is POST-only (a GET returns 404, verified).

Rate Limits & Notes

• Free tier: 50 credits/month (1 credit = 1 image) — small; paid plans scale.
• size=auto picks the best resolution; size=regular|medium|hd|full also available.
• Returns the processed PNG binary directly (use -o file.png).
• Supports image_url, image_file (multipart), and image_base64 inputs.
