The practical guide
Create compact photo-friendly JPG files from PNG.
PNG is lossless and excellent for transparency or crisp graphics. JPG is often smaller for photographs but cannot preserve transparent areas.
Photos versus graphics
JPG usually suits photographs. Logos, screenshots, diagrams, and text-heavy graphics can look sharper in PNG.
Lossy output
JPG discards some detail to reduce size. Inspect the preview and adjust quality rather than assuming one setting suits every image.

Frequently asked questions
Is my image uploaded?
No. The selected image is decoded and re-encoded inside this browser tab. The file and output are not uploaded to any server.
Can JPG keep transparency?
No. JPG has no alpha channel, so transparent pixels must be filled with a background color.
Will JPG always be smaller?
Not always. Simple graphics can already be more efficient as PNG.
