What Is DPI and How to Change It
DPI (dots per inch) defines how many pixels map to one inch of a printed image. This free DPI converter lets you change an image's DPI value - 72, 150, 300, 600 or any custom number - right in your browser with no upload. Whether you need 300 DPI for high-quality printing, 72 DPI for web use, or a specific value for a passport photo or document, just drag in your JPG, PNG or WebP and download the adjusted file.
Choosing the Right DPI
Use 300 DPI for professional printing and photos, and 600 DPI or higher only for fine-art or archival work. For screens and the web, 72 or 96 DPI is enough - DPI doesn't affect on-screen display, only print size. Keep in mind that changing DPI alone doesn't add detail to a low-resolution image; it only tells the printer how densely to place the pixels you already have.
