Is the image uploaded?

No. The scaling happens locally in your browser.

Does enlarging make it sharper?

No — enlarging cannot invent detail and may look blurry, so shrinking or proportional scaling is the safer choice.

Both are supported — pick whichever your target platform asks for.

Scale images by percentage or to fixed pixels — processed locally, files are never uploaded.
