MakeHDR vs other online HDR converters
Online 'HDR converters' range from real gain-map tools to contrast filters that upload your file. MakeHDR computes a real gain map for photos and true HDR for video, on your device — and adds a native app for iPhone, iPad and Mac.

| MakeHDR | Other online converters | |
|---|---|---|
| Real gain-map HDR (ISO 21496-1) | Yes | Some do, some apply a filter |
| Converts video to HDR | True HDR | Rare |
| Privacy | Stays on your device | Varies — some upload |
| No AI, no invented detail | Guaranteed | Varies — some use AI 'enhance' |
Check two things in any converter: does it write a real gain map, and does your file leave your device? MakeHDR computes standards-based Ultra HDR for photos and true HDR for video locally, with your pixels untouched. It's $39.99 once, free to try with a watermark.
