What PixMiller Background Remover API is
PixMiller Background Remover API removes image backgrounds through a REST API and returns transparent PNG results. Processing is synchronous and usually takes a few seconds, with a typical result URL in about five seconds. PixMiller states 99.8% edge precision and automatic handling for hair, fur, and semi-transparent edges. JPG, PNG, and WebP uploads up to 20 MB are accepted, along with public image URLs; the FAQ also lists BMP and a limit below 50 megapixels. Outputs support preview, full, or auto sizing, PNG or JPG formats, and transparent, white, or custom hex backgrounds. Batch processing, replacement backgrounds, and integrations for e-commerce, apps, ERP, DAM, and scripts are supported. The default rate limit is 40 images per minute per key. Results are deleted after three days. Platforms include API, web, Windows, and macOS. A free plan and free trial are available; listed credit plans have no visible prices.
