How can I compress JPG/JPEG and reduce file size?

JPEG compression is mainly controlled by the quality setting: lowering quality reduces file size but also removes more detail. Start around 0.8 and adjust down until you reach a good size/quality balance.

What are the characteristics of JPEG?

JPEG is a common lossy format, great for photos and usually small, but it doesn’t support transparency.

Does the quality setting affect JPEG?

Yes. Higher quality looks better but may be larger; lower quality is smaller but loses more detail.

Will my images be uploaded?

No. Conversion happens locally in your browser.
