Transform SDR photos and videos into HDR for modern HDR‑capable displays on recent iPhones, iPads, and Apple Silicon Macs.
Not to be confused with legacy “HDR” exposure‑blending filters - this is standards‑based HDR for brighter highlights on supported screens.
Note: HDR content will not display when your iPhone is in Low Power Mode, as HDR is disabled.
Key Benefits
• Works well with SDR AI images, DSLR photos, and film scans - especially high‑contrast scenes.
• Simple workflow: pick media (or drag & drop on iPad/Mac) and convert.
• One‑tap HDR for photos and videos; optional contrast/saturation tuning (video; photo experimental).
• Batch processing available in Pro.
Device Requirements
• HDR‑capable display (e.g., iPhone 11 Pro or later; iPad Pro with XDR; Apple Silicon Mac with XDR).
• iOS 18.1 or later.
How It Works
• Input: JPEG, PNG, HEIC, TIFF, PSD, RAW, MP4/MOV/M4V (H.264/HEVC)
• Output: 10‑bit HEIC with HDR metadata or JPEG UltraHDR (photos), HDR video (HEVC/H.265) ~100 Mbps
• Standards: BT.2020 color
Important
• HDR appearance varies by device, display, OS, and viewing app; specific results aren’t guaranteed.
• Some apps show HDR thumbnails over‑bright; non‑HDR devices may display HDR video too bright.
