I'm just saying from personal experience, saving the same HDR file from photoshop as an AVIF and a JPEGXL, the AVIF is a fraction of the size of the JPEGXL.

Edge now supports AVIF! (in the canary version but still)

Things are finally settling on a format!
AVIF image format | Can I use... Support tables for HTML5, CSS3, etc
 
Alright no more F**king around, let us save in AVIF.

So why is Avif not a saveable format in affinity photo?

Ok I didn't realize this before but I see why AVIF seems to be what people are leaning toward. The compression on those is INSANE.
a 8-12MB HDR/whatever is like 200KB in AVIF.
Photoshop supports this but affinity does not...
At this point maybe I just need to constantly campaign for AVIF support. that would easily replace JPEG. It just needs broader support. 

Also to be clear avif DOES work in most browsers just not edge. and does display as HDR in those browsers, it even works for text and such.
Just check this out, but finding this kind of support on a publicly uploadable website is a pain.

Never seen an 8bit Webp tho, and that works on everything...

Yeah there's lots of support in editing programs for all kinds of formats, the problem is consumer level. There's no solution for people to easily consume HDR images in a format that is also easy to create.
JXR is the closest I've seen to at least beginning to solve that problem due to native Windows support and Xbox. Or at least help create some sort of demand for newer formats to be supported. If there was a bunch of awesome HDR paintings/photos out there that people wanted to see but couldn't without downloading the file, that would help create the demand.
Photoshop is it's own shitshow cause it's not a default saving format it is a saving format ONLY in their cameraraw thing which requires steps to open up in a way that lets you save these formats unless you have lightroom. It's really stupid.
Yeah I guess but that didn't apply to videos DX, there's plenty of video support but no images support. 
Can't create demand if there's no working solution in the first place.
Is there even a way to make those? 🤔

Wait it was removed from edge?! But then why doesn't windows photo app open jpegXL!!!!? Why doesn't jpegxl work on anything?!
This whole thing is maddening...
Avif at least works on most browsers but edge, but for some reason I just don't expect any website to go out of their way for support so I mostly want desktop solutions.
I have resorted to complaining to Microsoft about it on their feedback hub. please upvote it.

I decided to cave and try paint.net from a HDR tif file, and it does what I expected outputs an SDR image. Based on the way the image looks when its loaded I assume the program dumps the 32bit color data when it loads and can't save it. And paint.net doesn't support any HDR or EXR formats either. 

Like just to illustrate, here's a JXR from Destiny

At the very least on windows, if you have an HDR display you can open this image and it just works (also works if you have an SDR display it tone maps). While it's not ideal to distribute this way in the age of the internet, it is a solution until demand makes these sites and browsers fix their shit.
No other format lets you do this.

The problem is distribution, JXR is the ONLY format you can view on an image viewer in HDR without using a photo editing program. It works by default in Windows 10 and Windows 11, JPEG XL does not. 
I can give people a JXR file, and while they may have to download it to view it, it at least will open in windows photos app in HDR with no additional work from the user besides needing HDR turned on, on their PC.
It is the most user friendly solution available, and it would be usable for now until all these platforms get their shit together.

It's abandoned on the software side but supported in a lot of other ways. AVIF has the same problems. 
JXR works on windows 10-11 with the default photo app in full HDR display, it's supported on Xbox and nvidia shield, edge supports JXR, so it's not Microsoft ignoring it entirely. I would wager the vast majority of consumer HDR image files is JXR.
AVIF while supported by photoshop requires an extremely specific process using Camera Raw to export an image like that, but also no default photoviewer on windows supports the format. AVIF is supported on browsers but it's extremely rare to see it, and it's not supported on edge. 
Neither of these formats work on phones which basically all have HDR displays.
There's an inconsistent format support here, but to me JXR is the best bet since it technically should be everywhere. And it's the only format supported by default at least on PC.
My purpose is I want to make HDR art.

Look at this, people have been BAFFLED by this for YEARS!
Affinity, you could solve a years old problem!

I'm just saying from personal experience, saving the same HDR file from photoshop as an AVIF and a JPEGXL, the AVIF is a fraction of the size of the JPEGXL.

AVIF is much smaller than JpegXL though, especially for HDR images. 

Hey Guys, 
AVIF support would be greatly appreciated. I know this has been a long requested feature since version 1 but still no word on when this will be implemented from Serif?
Thank you for JPEG XL but due to Google being just downright awkward and deprecating the XL codec in version M110 AVIF is really the only choice to use with current gen technology for higher quality smaller file sizes.
Can we please get an update on where things are with this?
Great job on the software. The future for these apps is very bright.
Kind regards
Mike
