Why compress JPEG images?

JPEG is the dominant format for photographs — every smartphone, camera, and photo app defaults to it. But unoptimised JPEGs are often far larger than necessary. A photo shot on a modern smartphone typically lands between 4 MB and 12 MB. At 82% quality, the same photo can be under 1 MB with no visible difference at normal viewing sizes.

Smaller JPEGs load faster on websites, pass through email servers without getting rejected, and take up less storage when you're sharing dozens of shots.

When to use each quality level

• 90–100%Archival, print, or further editing. Files stay large.
• 82% (default)General purpose. Visually identical to the original at 40–60% smaller file size.
• 70–80%Web pages and app images where bandwidth matters more than perfection.
• 60–70%Social media, messaging apps, email thumbnails. Visible compression at close inspection.
