How to use Image resize

Frequently asked questions
- Are my images uploaded anywhere?
- No. Resizing and compression run in your browser, so the image never leaves your device.
- Why does quality matter for file size?
- Lower quality discards fine detail to save space. For web thumbnails the difference is usually invisible while the file gets much smaller.
