Photoroom API

Photoroom API is an AI image editing API for e-commerce that helps developers, marketplaces, and brands automate product visual production at scale. The API exposes Photoroom's commerce-trained models through a single REST interface, built around a deliberately small set of endpoints that cover background removal, AI backgrounds and shadows, relighting, virtual model, flat lay, ghost mannequin, product beautifier, composition, reposition, upscaling, and image to video. Keeping the endpoint count low keeps integration simple and makes it easy to add capabilities over time. Founded in 2019 and headquartered in Paris, Photoroom has raised $64 million in total funding from investors including Balderton Capital, Aglaé Ventures (LVMH's investment arm), and Y Combinator. The API processes over 3 million images daily, with customers including Mercari, Wolt, DoorDash, Decathlon, Klarna, Smartly, and Warner Bros. Built for commerce, Photoroom API is used to embed visual production inside marketplace seller flows, DAM, PIM, and CMS platforms, retailer catalog pipelines, and creative automation tools. Where general-purpose image APIs optimize for creative range, Photoroom API is engineered for product fidelity and brand consistency across high volumes of SKUs. Key features and capabilities: • Two API products, Remove Background API and Image Editing API, that together cover background removal, AI backgrounds and shadows, relighting, virtual model, flat lay, ghost mannequin, product beautifier, composition, reposition, upscaling, and image to video, so you get the full commerce workflow without a sprawling set of endpoints to integrate. • Batch processing and a REST API designed for continuous catalog pipelines, with native connectors for the main PIM, DAM, and cloud stack. • Custom AI models trained on a customer's product types, channel formats, and brand rules, available on Enterprise contracts. • Brand Kit that locks backgrounds, shadows, padding, colors, logos, and channel formats once and applies them automatically to every future image, with role-based access for Owner, Editor, and Viewer. • Enterprise security and reliability, including SOC 2 Type 2 certification, GDPR compliance, encryption in transit (TLS 1.2+) and at rest, a 99.9% uptime target, dedicated account team, and documented escalation path into engineering for high-urgency API issues. • Self-serve onboarding with a free sandbox mode, so developers can sign up and run test requests at no cost before moving to a paid plan. Common use cases include seller enablement and listing standardization for marketplaces, automated product image generation for retailers and direct-to-consumer brands, embedded image editing inside DAM, PIM, and CMS workflows, and creative automation for ad-tech and AI content platforms producing commerce visuals at scale.
