Just select your preset and resize — no math, no guessing, no wasted time.

Does Resizing a JPG Reduce Quality?

It depends on what you do. Scaling a JPG down reduces its file size and may also cause a slight drop-off in onscreen sharpness, depending on how aggressively you resize. Scaling up does not bring back detail that was never there — interpolation adds new pixels attractively, but adds no pertness. In our tests, we found that reducing a 3000×2000 JPG down to just a size of 1200×800 at the same time with an 85% quality produced a clean look without visible degradation and dropped the file size from 2.1MB to just under 520KB.
