No sign-up. Your photo never leaves your device.
DPI is a label that tells printers and layout apps how large to print the image. Changing it keeps every pixel, so the photo looks exactly the same on screen and the file stays nearly the same size. To get a sharper print at a bigger size you need more pixels, not a higher DPI. Other formats? Convert them with the free image converter first.
