Image DPI Converter

Image DPI Converter is a free, browser-based tool that lets you check and change image DPI locally without uploading files, ensuring complete privacy.

What is Image DPI Converter?

Image DPI Converter is a web application that reads and modifies the DPI (Dots Per Inch) metadata of images directly in your browser. It accepts JPEG, PNG, and WebP files up to 20 MB, processes them entirely on your device, and outputs the same image with updated DPI settings. The tool is provided by imagedpi.org and requires no registration.
