About the NEF format
NEF is Nikon's RAW format, written by every Nikon DSLR since the D1 in 1999 and by every Z mirrorless body. RevelRaw opens NEF from both eras, starts from the neutral sensor data rather than your in-camera Picture Control, and ranks 50+ presets against the scene so you build the look yourself.
- Cameras
- Every Nikon DSLR since the D1 (1999) and every Z body; advanced Coolpix compacts write NRW instead
- Bit depth
- 12- or 14-bit on most DSLRs and early Z bodies; the Z8 and Z9 record every NEF at 14-bit
- Compression menu
- Uncompressed, Lossless Compressed and Compressed on DSLR-era bodies; newer Z bodies add High Efficiency modes
- Opens in macOS Preview?
- Yes for bodies on Apple's list, which runs from the D1 to the Z5II, Z50II and ZR; a brand-new body waits for a macOS update
- File size, public samples
- Z6 III (24 MP): 33 MB Lossless Compressed. D850 (46 MP, 14-bit): 55 MB lossless, 98 MB uncompressed. One file each
The NEF complaint editors hear most: the photo looked punchy on the camera and turns flat on the Mac. Your Picture Control, Standard or Vivid, is only a note in the NEF, and only Nikon's own software renders it. RevelRaw, like every other third-party editor, starts from the neutral sensor data. That flat start holds more highlight and shadow detail, and AI scene detection puts the best-matched presets first.
The compression menu matters more for disk space than for quality. On a D850 sample, a 14-bit Uncompressed NEF weighed 98 MB against 55 MB for Lossless Compressed, with every bit of sensor data kept in both. Lossless Compressed is the setting that loses nothing and opens anywhere NEF opens at all.

Pull back highlights and lift shadows without halos, add depth with Structure and cut through haze with Dehaze. Shift any of eight color bands with HSL, shape contrast with RGB tone curves, and compare with the original as you edit.

Which cameras does RevelRaw support?
Every Nikon DSLR since the D1 and every Z-series body, with NRW from the advanced Coolpix compacts alongside. RevelRaw also opens RAW from Sony, Canon, Fujifilm, Panasonic, OM System and the other major brands: 24 RAW formats from 15 brands. See every format RevelRaw opens.

What is RevelRaw?
RevelRaw is a Mac app for editing RAW photos. Open a Nikon .NEF file and RevelRaw recognizes what's in the shot, suggests the best-matched looks from its 50+ presets, and lets you fine-tune and export, all on your Mac.
Does RevelRaw apply my Picture Control?
No. Picture Controls are Nikon's own recipe, stored as a note in the NEF, and only Nikon's free NX Studio renders them exactly. RevelRaw starts from the neutral sensor data and ranks its presets against the scene. For the camera's look alongside the negative, shoot RAW+JPEG.
Should I shoot Uncompressed or Lossless Compressed NEF?
Lossless Compressed. It keeps every bit of sensor data in a much smaller file: a D850 sample weighed 55 MB lossless against 98 MB uncompressed, with no visible gain from the bigger file. It is also the setting every NEF-reading app supports.
What can I try for free?
Open, edit and compare unlimited photos for free, including syncing edits across a shoot. One full-quality single-photo export is included. Pro unlocks unlimited exports and batch export.
Will it work on my Mac?
You need macOS 26 or later and a Mac with an Apple M1 chip or later. RevelRaw is available in English, Spanish, Japanese, German, French, Italian and Portuguese. Check the current requirements on the Mac App Store before downloading.
Do I need editing experience?
You can start with a suggested preset and export, or refine the result with exposure, color, detail and crop controls. Preview your changes, compare with the original and use undo to explore different edits.
Does RevelRaw have film looks and HSL?
Yes. RevelRaw 4.8 adds 14 film looks inspired by classic slide, negative, cine and black-and-white film, and an HSL panel that adjusts hue, saturation and luminance in eight color bands. Structure and Dehaze arrived in 4.7. All of them are free to use; Pro adds unlimited and batch export.
Do my photos get uploaded?
Opening, editing, AI processing and exporting happen on your Mac. You do not need a RevelRaw account. You need internet access to download the app or buy Pro through the App Store.
Can I export for social media and print?
Yes. Export as JPEG, PNG, TIFF or HEIF, with presets for social media, stock sites, print and web. Set the dimensions, quality and color space for your destination, and add copyright and other metadata to the file.
Can I edit a whole shoot at once?
Yes. Open a folder or multiple RAW files, refine one photo, then Sync, Copy or Paste selected settings across the others. Batch editing is free and can be undone in one step. Pro adds batch export of your selection or the whole shoot.
Can I edit just part of a photo?
Yes. Masks are free, with no Pro required. Use linear gradients, radial gradients and a brush on macOS 26 or later.

Gradient and brush layers can be synced across compatible photos; AI selections are not copied.
Can I bring my Lightroom presets and edits?
Import compatible Lightroom .xmp presets and .cube color LUTs. Supported Lightroom adjustments can also be read from a DNG or an accessible XMP sidecar beside your RAW file, including its crop and straighten angle. Adobe profiles and masks are not imported, and rendering can differ. This does not import your Lightroom catalog.
