UltraHDR JPEG Workbench

Examples

UltraHDR JPEG Gain Map Tool

Inspect UltraHDR JPEG gain maps locally, compare SDR/HDR previews, tune export presets, and export gain-map JPEG or inspection JSON.

What This UltraHDR JPEG Tool Covers

Use this page when the delivery target is a gain-map JPEG rather than a classic .hdr or .exr file. It reads UltraHDR or Adobe Gain Map content locally, compares SDR and HDR preview intent, keeps export presets visible, and produces gain-map JPEG or inspection JSON outputs.

Supported UltraHDR workflow scope

  • Input focus: UltraHDR JPEG and gain-map based JPEG assets used for modern HDR image delivery.
  • Output scope: browser-side UltraHDR or Adobe Gain Map JPEG exports, PNG preview, config JSON, and inspection JSON.
  • Best fit: JPEG gain-map inspection, SDR/HDR comparison, mobile-oriented HDR delivery checks, and export preset validation.

When to use this tool

  • Inspect gain-map based JPEG assets before shipping them to modern HDR-capable viewers and mobile devices.
  • Compare SDR and HDR preview behavior when tone mapping and export settings still need tuning.
  • Export UltraHDR or Adobe Gain Map JPEG outputs while keeping preview, quality, ICC, EXIF, and boost settings aligned.

FAQ

Does this read gain-map JPEG files?

Yes. The workbench reads supported UltraHDR and Adobe Gain Map JPEG content and shows the detected format when a file loads.

Is UltraHDR output aimed at mobile compatibility?

Yes. The presets are organized around web, Android-style UltraHDR, and Adobe Gain Map delivery choices.

Will tone mapping settings be reusable?

Yes. You can export and import the UltraHDR configuration JSON, and the inspection report records the active preview and export settings.
