Want quality slider with percentage back in photoshop when exporting!

[Nina5E87]

In photoshop if I navigate to  file> export > export as there used to be a percentage quality slider to adjust the size of each jpg you want to export. For example I need a web ad to be as close to 500kb as possible without going over for best quality, that slider allowed you to do that. Now the quality slider is just low to high 1-7, this has way bigger jumps in quality. Our team has had to revert to version 22.2 to get this the percentage slider back. 

Is there a fix for this on the current version? I'm on a M4 chip Pro Mac if that is relevant. 

I hope that in future versions the quality slider will have its previous capability, being able to adjust by percentage again!

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

@Nina5E87 you can get it back by enabling this option in preferences

Export now uses a newer jpeg encoding module which only has 7 steps. "Legacy Export As" is available in Windows and older Macs, but not supported on Apple Silicon.

This needs to be said for anyone else reading this. The file size : image quality ratio for jpeg is a highly moving target, and the final file size depends more than anything on image content. A given size limit will require highly variable compression levels to reach that size. In other words - to get 500 kB, one image may need quality level 2, while another, exactly same pixel size, arrive at that size with quality level 7.

These two are the same size and compression level - the first is 52 kB, the second is 438 kB:

The point is - maybe a fixed size limit isn't the most efficient way to approach this. Maybe it's better to allow some to go under and some to go over, averaging out. And then the number of steps isn't critical anymore, they will correspond more to differences you can actually see.
