Questions

Will resizing reduce quality?

Making an image smaller keeps it sharp. Making it much larger than the original can look soft, because no new detail can be created.

What does lock aspect ratio do?

It keeps the width and height in the same proportion as the original, so the image is not stretched or squashed.

Is my image uploaded?

No. Resizing happens in your browser and your image never leaves your device.

Which format should I choose?

JPG is best for photos, PNG for graphics with transparency or sharp edges, and WebP for small files on websites.
