Kavij
Kavij uses AI segmentation to remove image backgrounds and create transparent results.
What Kavij is
Kavij uses AI segmentation to remove image backgrounds and create transparent results. Its models are listed for people, hair, pets, products, illustrations, and anime, with standard, precise, fast, and anime options. Editing tools include hair and fur refinement, erase and restore brushes, shape selections, background colors, gradients, and blur. Uploads can be JPG, PNG, or WebP, and downloads can be transparent PNG or JPG; the homepage lists an upload limit of 20 MB. The free plan costs nothing, requires no sign-up, adds no watermark, and has no per-image limit. Kavij also supports batch processing, replacement backgrounds, commercial use, and API access. Its Docker-based self-hosted API has POST /api/remove and GET /api/health endpoints, with no per-call fees, and its source code is under the MIT license. Kavij says AI removal sends images to its server for in-memory processing, while touch-ups, background adjustments, and downloads run locally in the browser.
