Question

Problem: When saving a JPEG, Quality: 7 is smaller than Quality: 6

Hi guys,

How do I report a bug to the Photoshop team?

 

I have noticed a recurring problem when saving a JPEG (save as)

In the 'JPEG Options' window, when I change the 'Quality' number, the file size for Quality:7 is always smaller than Quality:6 

 

(I'll include screenshots below)

 

The other 'Quality' numbers (1-12) have corresponding file sizes that follow a logical progression of smallest to largest file size. It's just Quality: 7 that is the exception. It is consistently smaller than 6.

Extra info:

I'm using Adobe Photoshop 2024 (Creative Cloud) on a Windows desktop.

 

Note: I use computers every day and Photoshop most days, so I'm used to trouble-shooting problems. I would appreciate if replies to this post would please skip comments like "Did you try turning it off and turning it back on again?" Cheers ears.

 

Kind regards,

Bex

    I did some testing in version 2021, where I noticed the discrepancy between Save As JPEG Level 2 vs. Level 3 quality.
