HIF files: HEIF from Canon, Sony, Nikon and Fujifilm

What is a .HIF file?

HIF is a short file extension for a HEIF image. IANA's registrations for image/heif and image/heic both list .hif, and the Library of Congress describes it as an extension added to the standard in a 2020 corrigendum. Inside, a .HIF is the container described in HEIC vs HEIF: a meta box, coded pictures, usually HEVC. What sets camera files apart is what the maker puts in them. Phones write 8-bit pictures to be shared; the camera manuals below describe HDR curves, 10-bit gradation and, on some Sony bodies, 4:2:2 colour.

Which cameras shoot HEIF, and what do the makers say?

Two patterns hold across the brands we could read. Camera HEIF is bound up with HDR: Canon only offers it with HDR PQ, and Nikon and Panasonic tie it to HLG. And makers expect you to need their software or to rename the file: Fujifilm and Panasonic say so outright, Sony says some software cannot view or edit it, and Nikon's HLG guide says to view HLG photos you need NX Studio and a codec Nikon calls Imaging Codec 01, installed the first time you open a .hif in it.

Is camera HEIF the same as an iPhone HEIC?

The container is the same. The difference is what is inside. In the Inspector our sample reports brand heix, the HEVC Range Extensions profile, 4:2:2 and 10 bits; a typical 8-bit HEIC reports heic, the Main Still Picture profile and 4:2:0. The brand tells a reader which HEVC profiles to expect. The HDR is different too: camera files describe it with a PQ or HLG curve on a 10-bit picture, whereas Apple's iPhone approach is an ordinary picture with a gain map; see HEIC HDR. Which brand a given camera writes we did not check, since we have none; to find out, drop a file into the HEIC Inspector.

Why won't my .HIF file open?

Four causes, in the order to check. First, the name: some software refuses .hif even when it would read the contents; Fujifilm and Panasonic say to rename to .HEIC, and an Adobe staff reply says Photoshop recognises only .heic and .heif. Rename a copy. Second, the codec: Microsoft's listing for the HEIF Image Extension says the HEVC Video Extensions must be installed to view .heic, .hif and .heif files. Third, the profile: 10-bit and 4:2:2 need HEVC's Range Extensions, which software built for iPhone photos may not read. Capture One's help page says it supports 8-bit HEIF and not 10-bit HEIF from newer cameras. Fourth, HDR: a PQ or HLG picture opened in an app that ignores the curve looks flat.

Our sample isolates the third cause. camera-style-10bit-422.hif is a synthetic test chart, not a camera file: brand heix, HEVC Range Extensions, 4:2:2, 10 bits, a .hif name, no Exif and no HDR curve (its colour is plain sRGB). If your viewer opens the ordinary 8-bit sample and not this one, the profile is the problem; if it rejects both, look at the name and codec. Download it from the sample files page.

How do I open HIF files?

How do I convert HIF to JPG or PNG?

Drop the file into HEIC to JPG or HEIC to PNG; they decode HEVC inside your browser with their own decoder, so they do not depend on what your operating system supports, and they accepted the .hif name. We tested five of our converters with camera-style-10bit-422.hif:

So conversion works, and the cost is bit depth and, for JPG, colour resolution: a 10-bit 4:2:2 picture comes out 8-bit, and the JPEG halves the colour detail again to 4:2:0. For editing a 10-bit file, Sony's advice for its HEIF is a 16-bit TIFF from Imaging Edge Desktop, because TIFF keeps the 10-bit gradation; our HEIC to TIFF did that in our test, writing a 16-bit TIFF from the 10-bit sample. If the file is an HDR (PQ or HLG) picture and you only need to share it, convert it with the HDR caveats in mind, or view it in the maker's software.

What does our sample test?

Three things at once, which is the point. It has a .hif extension. Its brand is heix rather than heic. And its stream is HEVC Range Extensions at 10 bits with 4:2:2 chroma, the kind of file the Sony FX30 page describes as “HEIF 4:2:2 10bit”. Pass: the standard chart, accepted despite the name. Fail: a rejection by extension before the contents are read, or a profile error from a decoder limited to the Main profiles. It is a stand-in; we have no camera file to test, and a real one also carries Exif, maker notes and often a PQ or HLG tag.

How we checked

Makers. Every statement in the table comes from a manual or help page opened on 2026-10-12 and is limited to that page; the model is named where the page names it. We could not open Canon Europe's specification pages, Samsung's S10 article or Adobe's Lightroom help (all returned an access block), so we used none of them directly. Sample. camera-style-10bit-422.hif is built by our sample scripts (see public/samples/manifest.json). We read it with the Inspector (brand heix, Range Extensions, 4:2:2, 10-bit) and ran it through the five converters with Playwright and Chromium, then compared the outputs with a Pillow 12.3.0 decode using pillow-heif 1.8.0. Not done: inspecting a file from a real camera, or opening one on macOS, Android, or in any Adobe app.
