What it does
Every picture comes out at 3840×2160. "Crop to fill" cuts the edges that don't fit; "fit" keeps the whole picture and fills the sides.
When to use it
4K wallpapers and TVs. Many sites and apps reject or blur pictures that aren't the size they expect.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
