About the Change DPI Tool
Changing DPI (dots per inch) modifies the print resolution header tags of your image. This tool allows you to change the DPI of JPG and PNG images locally in browser memory without re-compressing the image, ensuring no quality loss. Standard density options include 72, 96, 150, 300, and 600 DPI.
