How to use the Compress JPEG

How JPEG compression works
JPEG splits an image into small blocks and stores the detail your eyes are most sensitive to, discarding the rest. The quality setting controls how much is kept. Cameras and phones save at 90–100% quality, which is far more than a screen needs. Re-saving at around 75% often cuts the file size by 60–80% with no difference you can spot.
Faster websites and happier visitors
Images make up most of the weight of a typical web page. Compressing your JPEGs before uploading them to WordPress, Shopify or any site builder makes pages load faster, improves Google PageSpeed scores and saves mobile data for your visitors.
Frequently asked questions
What JPEG quality should I use?
75–80% for websites and sharing, 85–90% for photos you may print. Below 60% you may start to see blocky artefacts.
Can I compress a JPEG without losing any quality?
Not meaningfully. JPEG is a lossy format, but at 80% the loss is invisible for normal viewing while the file is several times smaller.
Does compression remove EXIF data like location?
Yes. Re-encoded images don't keep EXIF metadata such as GPS location and camera details, which is a nice privacy bonus when sharing photos online.
