RemoveBg

Remove.bg is the tool that popularized automatic one-click background removal. It's the most widely known in the category, part of the Kaleido ecosystem, with an API widely used by developers to integrate the feature into their own applications.

Remove.bg is the reference platform for automatic background removal from images. Developed by Kaleido (now part of an ecosystem that also includes Designify), it's based on segmentation algorithms that distinguish the subject from the background with great precision, especially on photos of people — where it achieves results hard to match in terms of speed. It works instantly: you upload or paste an image, and within seconds the background disappears, leaving the subject on transparent, downloadable as PNG. You can add an alternative background from the integrated library or upload your own. The web editor lets you refine the result on difficult edges like hair. The free version produces low-resolution previews (0.25 megapixels); for high resolution you use credits purchasable individually or via subscription. The API is extremely popular among developers because it lets you integrate background removal into applications, ecommerce workflows and third-party tools with a few lines of code.

For designers, photographers, ecommerce sellers, social media managers and developers who want to quickly remove backgrounds from images, with a robust API for automated integration.

Remove.bg is free for low-resolution previews (0.25 MP), without registration. For high-resolution images you purchase credits (from $0.20 to $1 per image based on volume) or subscribe to a monthly plan with a fixed number of included credits, starting at around $9 per month. The API has volume-based pricing, with a free tier of 50 images per month. Kaleido often offers bundles combining remove.bg and Designify.
