# HDRJPG HDRJPG is an API and SDK developer platform that converts iPhone HEIC, Android UltraHDR (Gain Maps), and EXR photos into universally compatible web formats (AVIF, JPEG-XL, and standard JPEGs). It solves the problem of cross-browser HDR compatibility, allowing developers to deliver Instagram-quality true-HDR images to users with a single API call, while providing graceful fallbacks to Standard Dynamic Range (SDR) for unsupported devices. It is built for image-heavy platforms like Real Estate, Travel, E-Commerce, and Social Networks, featuring privacy-first European processing. ## Documentation - [API Documentation](https://hdrjpg.com/documentation/api): Learn how to integrate the REST API to convert and standardize HDR images. - [SDK Documentation](https://hdrjpg.com/documentation/sdk): Official SDK libraries for interacting with the HDRJPG service. - [Embedding Guide](https://hdrjpg.com/documentation/embedding): Instructions on using the embed snippet to automatically serve the most efficient true-HDR format supported by the user's browser. ## Showcases - [NASA Artemis in HDR](https://hdrjpg.com/showcases/nasa-artemis): Gallery of Artemis II crew photography — the first human-taken photos from lunar distance since Apollo 17 in 1972 — manually remapped to HDR and embedded using HDRJPG technology. ## Resources - [Examples](https://hdrjpg.com/examples): Visual before-and-after examples demonstrating true HDR delivery on compatible screens. - [Pricing](https://hdrjpg.com/pricing): Subscription tiers and API usage pricing. - [Convert online](https://hdrjpg.com/try): Upload and test HDR conversion directly from the browser. ## Legal - [Terms](https://hdrjpg.com/terms) - [Privacy Policy](https://hdrjpg.com/privacy) - [Agreement](https://hdrjpg.com/agreement)
