Until you get to 85%, nothing really changes.

Choosing say 80% quality, is the same thing as choosing 77% or 84%.

So what does this mean? It basically means that some numbers don’t matter at all, while others do quite a bit when we use the percentage scale. * Space Savings represented relative to the largest file size at 100% Quality (27.3 MB) and full resolution (captured with a 20 MP camera) Now let’s take a quick look at the table below, where the 0-12 values from Photoshop are mapped to percentages: PS JPEG Compression # Here we see the representation of the JPEG compression scale from 0% to 100%. First, here is the screen that shows up when you click “Save” or “Save As” and choose JPEG in Photoshop:Īs you can see, the values you can choose from a represented in a number scale from 0 to 12. This ultimately means that changing from one number to another, like from 85% to 90% might make no difference whatsoever in compression or image size, while changing from 84% to 85% would make a big difference.īelow are the different screens we are used to seeing. Adobe simply mapped the 0 to 12 scale to the percentage scale. The truth is, the percentages we see in Lightroom do not really scale from real 0 to 100 in single digits. While percentages are easier to understand than numbers from 0 to 12, as we relate to 100% being the “best image quality” easier, Adobe also created a confusion as to what number represents what percentage, since the ranges of numbers are not provided in any of the help documents. Photoshop gives us compression levels from 0 to 12 when saving JPEG images through the “Save” or “Save As” dialog, while Lightroom only allows us to input a percentage. Determining the ideal JPEG quality setting in both Photoshop and Lightroom can be challenging, because we often see two different values to choose from.
