Enlarging an image (upscaling) does not improve quality: pixels are interpolated, the result stays blurry. Always start from the highest available resolution.
A 4000×3000 (12 MP) photo taken with a smartphone weighs about 5 MB. Resized to 1200×900 for the web, it will weigh about 300 KB with no visible quality loss on screen.
