Photoshop 23.4.2 - PSB RLE compression - PLEASE ADD THIS AS AN OPTION IN FUTURE RELEASES ADOBE!

RLE compression is possibly the oldest type available on computers. It works great for SOME files and is pretty much useless for others - all depending on content. I'm fine with having it, as noted, OPTIONAL. But Adobe has other considerations besides just performance.

Just a rundown. My own position is yes, as long as it's optional and I can continue to save uncompressed.

• As compression goes, it seems clearly superior to existing algorithms. Especially open/save times, which is the main show-stopper today.
• It would break compatibility for older Photoshop versions. This is how it already works for Illustrator and InDesign - you generally can't open new files in old versions. Photoshop, with its universal compatibility, is actually a special case.
• It would not be possible to get around it with "maximize compatibility". A flattened composite is no use if you can't open the file. But it would be possible to deliberately avoid it by saving uncompressed.
• As long as you stay current, you'll be fine regardless. But with with the accelerated rate of dropping backwards compatibility from both Apple and Microsoft nowadays, more and more users will be unable to stay current at all times. This, I think, is the major practical concern.

Absolutely - exactly my original point. Thank you and glad you agree @Aqua35069516m2jl 

Please Adobe add the tick box in preferences!

The RLE compression introduced in Photoshop 23.4.2 was a game-changer for studio workflows, especially for those relying on shared servers. While some users may have concerns, a 'save with RLE compression' checkbox in preferences would be immensely beneficial. It significantly improved save times without drastically increasing file sizes. Our studio is stuck on an older version due to this crucial feature. Current versions with compression are impractical for large files over a network. Please consider implementing this option to enhance user flexibility and maintain efficiency. 

@Lumigraphics I dont agree, I've tested it myself as far back as I can and it works. I'm not here to argue with you, I just want Adobe to listen and add this OPTIONAL tick box. Thank you.

If you have a new kind of compressed image data that older version of the app don't know about, then yes you've broken compatibility.

It wouldn't break it, we save PSB's everyday with the RLE compression from 23.4.2, it opens in any version of photoshop and vice versa. They open much quicker than anything compressed with the standard compression too!

But yes as you say, PSB is their format, so hopefully this is easy enough for them to just to add a tick box for us all!

That doesn't matter. Compression is available in Photoshop, and there are numerous different methods. Since PSB is not a standard, Adobe doesn't have to go through an approval process to add it.

Of course, adding compression would probably break PSB for older versions of Photoshop. That's the downside to changing a file format.

@Lumigraphics please read the OP, this is about compression on layered PSB's only.

Adobe added AVIF compression in Camera RAW, I think just for DNG files. I'm betting that some combination of AVIF, RLE (which is ancient and used all over computing), HEIC, and JPEG2000 would be able to hit all the goals.
