What is DPI and Why Does it Matter?

DPI stands for Dots Per Inch. It is a measurement of video or print density, specifically the number of individual dots that can be placed in a line within the span of 1 inch. While pixels determine the digital size of your image, DPI determines how large or small the image will appear when printed.

For example, an image with 300 DPI is the standard for high-quality professional printing, whereas 72 DPI is typically used for web graphics to ensure fast loading speeds.

How to Change DPI Without Losing Quality?

Our tool works by modifying the EXIF metadata of your image. Unlike traditional resizing tools that stretch pixels and cause blurriness, this converter simply tells the printer or software how many pixels to display per inch. This preserves the original clarity and sharpness of your photographs.

Is 300 DPI better than 72 DPI?

Does this tool reduce image quality?

No. This tool specifically changes the metadata density. It does not compress your image or remove pixel data.
