An API and SDK to convert iPhone HEIC, Android UltraHDR, and EXR photos into universally compatible web formats. Deliver Instagram-quality HDR to your users without the engineering headache.

Why is Web HDR so hard?

Building web HDR from scratch means dealing with undocumented gain map standards, compiling custom image parsers for HEIC, and juggling AVIF/JPEG-XL browser support. HDRJPG handles all of this in a single API call: 
curl -X POST https://api.hdrjpg.com/convert \
    -H 'api-key: {*YOUR_API_KEY*}' \
    -F '[email protected]
    -F 'variant=[{"width": 1200, "format": "jpeg-xt"}, {"width": 1200, "format": "jpeg-xl"}]'

Perfect for image-heavy platforms

Real Estate & Travel
Show properties with blindingly realistic sunlit windows and deep shadows. Stand out from competitors with lifelike virtual tours.
E-Commerce
Make jewelry, cars, or glossy products pop off the screen. Higher dynamic range leads to better product representation and higher conversion.
Social Networks
Don't compress away the photographer's hard work. Support native iPhone and Android HDR uploads seamlessly for your users.
Privacy First (GDPR)
All photos are securely processed on our servers in Europe. They are stored only momentarily during conversion and are immediately and permanently deleted once the process is complete.
Graceful fallback
Resulting images can be embedded in websites and they display in HDR, falling back to standard dynamic range in non-compatible devices.
Non-HDR to HDR
Non-HDR images can also be provided and expanded to HDR, unlocking extended brightness and dynamic range for non-HDR sources.
