About Us
About DPI Converter
DPI Converter is a free, browser-based tool that lets you change the DPI (Dots Per Inch) metadata of your images instantly — no uploads, no servers, no sign-ups.
We built this tool because we were frustrated with existing DPI converters that required uploading images to unknown servers, showed ads everywhere, or didn't actually work. Our tool runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
Our mission is to provide a fast, reliable, and privacy-respecting DPI conversion tool that anyone can use for free — whether you're a photographer preparing prints, a designer sending files to a client, or a student working on a project.
