P: Can't open Canon HIF / HEIC Files

As a practical workaround, it may be easier to convert the HIF/HEIC files to a more widely supported format such as JPG or PNG before opening them in Photoshop. That avoids compatibility issues between Canon’s HIF implementation and Adobe/Windows codecs.You can do the conversion quickly with an online HEIC-to-JPG converter

@TexPhoto12 I don't actually see all those options in my Preferences. I'm using Camera RAW 17.1.0.2100 and when I click the Settings wheel I only get three options:

1. General (Appearance, Panels, Zoom and Pan, Keyboard Shortcuts)
2. Performance (Use Graphics Processor, Camera Raw Cache settings)
3. Technology Previews (Use New AI Features/Settings Panel or not)

Nowhere do I see anything to do with File Handling in any of the headings.

I, too, am feeling a little jilted about the lack of native support for Canon HIF files...especially given how much we pay these people.

The way to fix this is to open preferences for Photoshop > Camera Raw then select Automatically open all supported JPEGs  and HIECs.

If struggling with this issue still i have used this website called https://mergetwoimages.com/heic-to-jpg heic to png, jpg conversion and it works great you can also give a try its not much reliable but it will done the job for you

Try out this HEIC file example at https://filesampleshub.com/format/image/heic

There is a canon heif extension for dpp. 

Windows is not able to handle. Seems like have to go to MAC.

However like many of you suggested , I tried the canons dpp software

Any help would be appreciated, Thank you.

0. This is 2022.MAR.09., we are paying huge amounts on money for CC subscriptions, but Adobe still did not made anything to be able to open Canon HIF files for about 2 years! 😞 

1. Canon's HIF is 10 bit.

2. Canon Digital Photo Professional (or DPP, a free app for Canon owners) can convert that HIF to JPG, TIFF8, TIFF16.

I suggest to convert HIF files to TIFF16 (16bit TIFF) with DPP, and then you can go to Bridge/CameraRaw/Ps with that TIFF16 file if it needed.

Or You can edit the HIFs completely in DPP, without using any Adobe app, and then save to any format You want (JPG for web, TIFF16 for art print etc.). 

Not sure if it is a Adobe or Canon problem, but I have to say it it mostly Canon, since they put out this format that nobody else supports. The only way I know of working with HIF files (on Windows 10) is by opening them in Canon's Digital Photo Professional 4 (yes, this is the only application that will open HIF files that I know of in Windows), then having the file transferred/opened up Adobe Photoshop.  When you do that, it will be a TIF file. For me, kinda useless since I don't work with TIF files and don't want to go through various conversions.

Until/unless this is resolved, I am only going to have my Canon EOSR5 save in jpg format. Not worth the trouble at this point to use Canons HIF files.
