Download MergeHDR
Free to try, every device. Unlimited saves are $19.99 once or $9.99/year — Universal Purchase across iPhone, iPad and Mac, with Family Sharing, no accounts, no per-photo fees.
MergeHDR ships as two separate App Store listings — one for iPhone and iPad, one for Mac — so App Analytics can tell which platform actually drove the install, instead of a single link that hides Mac downloads inside the iOS number. Pick the button for the device you're setting up now; buying on either one unlocks MergeHDR everywhere else you're signed in, thanks to Universal Purchase.
iPhone & iPad
Grab MergeHDR from the App Store. Detection and merging work the same on iPhone and iPad — pick whichever device your bracket sets are already sitting on.
Download on the App StoreRequires iOS 18 or iPadOS 18 or later.
Mac
The Mac App Store listing is the same app and the same unlimited unlock — $19.99 once or $9.99/year — Universal Purchase covers it, so there's nothing extra to buy if you already own MergeHDR on iPhone or iPad.
Download on the Mac App StoreRequires macOS 15 or later. Runs natively on Apple silicon and Intel Macs.
System requirements
- iPhone / iPad: iOS 18 or iPadOS 18 or later.
- Mac: macOS 15 (Sequoia) or later — Apple silicon and Intel both supported.
- Storage: plan for extra headroom while a bracket set's originals and the merged export briefly coexist in your library.
- No account required on any platform — purchase is verified through the App Store, and Family Sharing extends it to your family group.
Supported formats
MergeHDR detects and merges exposure brackets shot in any of the following formats, mixed or matched within a set:
- Canon CR3
- Sony ARW
- Nikon NEF
- Fujifilm RAF
- Olympus / OM System ORF
- Panasonic RW2
- Adobe DNG
- Apple ProRAW
- HEIC
- JPEG
Export the merged result at full quality, or compress it to HEIC on the way out using the same on-device pipeline as our other app, RAWtoHEIC (opens in a new tab).
Not sure which one to grab?
If your bracket sets live in one Photos library synced across your devices, it doesn't matter which App Store listing you start with — install on your iPhone tonight, add the Mac app tomorrow, and Universal Purchase means you're never asked to pay twice.
