Why compress JPG?
JPG is the web standard for photos, but uncompressed camera JPEGs are often 3–8 MB. Compressing to under 200 KB dramatically improves page load speed and Core Web Vitals scores.
How much can you save?
At 80% quality setting, most JPEG files shrink by 60–80% with no perceptible visual difference. A 4 MB photo becomes 600–800 KB.
Is quality affected?
At our default 80% setting, the difference is invisible to the human eye. JPG uses lossy compression that discards detail your eye won't notice anyway.
