What Kavij is

Kavij removes image backgrounds and makes the result transparent. Its models cover people, hair, pets, products, illustrations, and anime, with standard, precise, fast, and anime options. You can upload JPG, PNG, or WebP files up to 20 MB and download transparent PNG or JPG images. Editing tools include hair and fur refinement, erase and restore brushes, shape selections, background colors, gradients, and blur. The service supports batch processing, replacement backgrounds, API access, and commercial use. Its free plan costs nothing, requires no sign-up, adds no watermark, and has no per-image limit. For self-hosting, Kavij describes a Docker-based API with POST /api/remove and GET /api/health endpoints, no per-call fees, and source code under the MIT license. Kavij says AI background removal processes images in server memory without saving them to disk or a database, using them for training, or sharing them with third parties. Touch-ups, background adjustments, and downloads run locally in the browser; AI background removal sends the image to Kavij’s server.
