Brackt: RAW to HDR Merge

Merge RAW brackets into professional HDR images, entirely on your iPhone. No desktop, no cloud, no uploads.

3 free merges included. No sign-up needed.

Brackt is the only iPhone and iPad app built exclusively for bracketed RAW to HDR merging. Import your exposure brackets, merge in seconds, and export professional HDR with full dynamic range. No cloud, no account, no cables.

Key Features

• HDR Merge: Combine 2-7 bracketed exposures into one high dynamic range image

• Two Merge Modes: Standard fusion is fast and forgiving. Great for handheld brackets and tricky scenes. Radiometric mode reconstructs true scene radiance for superior pixel-level detail on precise, well-balanced brackets.

• 10 Tone Mapping Algorithms: Reinhard, ACES Filmic, Hable Filmic, Drago, Durand, Ward Local Adaptation, Photographic, Exposure, Exponential, and HLG. Switch styles on the result screen without re-merging. Thumbnails preview each look in real time.

• Advanced Deghosting: 4 sensitivity levels (None, Low, Medium, High) for clean results even with moving subjects, flowing water, or wind-blown foliage

• Auto Alignment: Corrects camera movement between exposures. Works with handheld brackets and imperfect tripod shots.

• Lens Correction: Automatically corrects lens distortion as your RAW frames are decoded, so straight lines stay straight across the merge.

• In-App Photo Editor: Adjust tone, color, and clarity. Apply presets. All without leaving Brackt.

• Export Manager: Choose format (HEIC, 16-bit TIFF, JPEG, PNG), resize, and add borders before saving.

• Full RAW Support: DNG, CR3, NEF, ARW, RAF and large JPEGs. Extensive camera brand coverage including DJI Mavic and other drone RAW files.

• 16-bit TIFF Export: Take your HDR straight into Lightroom, Capture One, or Photoshop

• HEIC Export: Real HDR on Apple displays using the ST.2084 PQ transfer curve

• Share Extension: Send brackets to Brackt directly from the Photos app or Files app

• 100% On Device: Private, fast, and works everywhere. No internet needed.

• 30 Languages: Brackt follows your device language automatically, including Chinese, Japanese, Korean, German, French, Spanish, Turkish, and many more.

Built for Photographers Who Shoot with Purpose

Exposure bracketing lets you capture scenes the way your eye sees them. Brackt turns those brackets into a perfectly merged HDR image, right from your iPhone.

From golden-hour landscapes to dramatic architecture to night cityscapes, Brackt gives you the dynamic range control you need, right where you shoot.

No External Services. No Hidden Costs.

Unlike apps that send your photos to remote servers for processing, Brackt runs its entire merge engine on your device. No images leave your phone. No cloud compute costs baked into the price. Works at full speed in the field, on a plane, or anywhere with no signal at all.

Perfect For

• Landscape Photography: Preserve sky detail, clouds, and shadow texture in a single image

• Architecture: Balance bright windows with dark interiors and mixed lighting

• Travel & Cityscapes: Capture night scenes and golden hour with full tonal range

• RAW Workflows: Export 16-bit TIFF files directly to Lightroom, Capture One, or Photoshop

• Bracketed Merging: Precise alignment and intelligent fusion across all exposures
