Change image DPI
Set the print resolution in a PNG without changing its pixel dimensions. Change DPI information for printing; this does not add detail or upscale the photo.
Choose an image, then create your result.
How to use it
Keeps the pixel dimensions and writes print resolution into a new PNG. Choose 72, 96, 150, 300 or 600 DPI. Increasing DPI does not add pixels or improve detail. Some apps ignore this information; the displayed print size uses your chosen DPI.
The original stays unchanged. New PNGs may differ in size and color appearance. Visible text, faces and location clues in the image remain.
