When to use Compress Image
Reach for this when a picture is too heavy for an attachment limit or slow on a web page. Three levels let you trade quality for size deliberately: basic for barely-visible loss, moderate for a solid cut, strong when size is the only thing that matters. Photographs handle compression well; screenshots and text-heavy graphics show artefacts sooner.

Troubleshooting
Text in a screenshot looks smeared
JPEG compression handles sharp edges poorly. Use Basic, or keep screenshots as PNG.
Transparency disappeared
Output is JPEG, which has no alpha channel. Transparent areas are flattened onto white.
The upload is rejected before anything happens
The file is over the 20 MB cap. Compress it first, or split a long PDF into smaller files and process them separately.

Frequently asked questions
Compressed images are exported as JPEG, which compresses more efficiently than PNG for photos.

WebP makes smaller files than JPG or PNG at the same quality. It's also the format that half your desktop software still refuses to open.
