Glowroom: SDR to HDR Converter
Real HDR gain maps for photos
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn any SDR photo into true HDR. Glowroom writes a real HDR gain map — not a filter — so your photos glow on HDR displays. Finds your non-HDR photos. 100% on device.
Shot in SDR? Convert it. Already HDR? Relight it.
Glowroom turns any photo into true HDR. It synthesizes a real HDR gain map — the same technology behind iPhone HDR photos — so your images glow with brilliant highlights on HDR displays and still look great everywhere else.
Glowroom does both, entirely on your device — free and private, no uploads.
FIND YOUR NON-HDR PHOTOS
Proprietary feature -- Glowroom scans your entire library to discover every SDR (Standard Dynamic Range) photo. Filter by date or device, omit screenshots, and collect them all into a single album with one tap. Your best candidates for HDR conversion.
PRECISION EDITING
• Levels correction with a live histogram — drag the black, white, and midtone points like a pro

BUILT NATIVE for iOS.
• Real gain-map export (HEIC & Adaptive HDR JPEG)
