Frequently asked questions
How does it hit the size?
It walks a ladder of qualities and dimensions from best to worst and keeps the first that fits under the target.
What if it cannot get there?
You are clearly shown the requested target and the real minimum achieved, and you decide.
JPG or WEBP?
WEBP compresses further at the same look; JPG is more universal. If your destination accepts it, WEBP gives smaller files.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
