The image DPI converter changes the dots-per-inch resolution of your images. DPI determines print size — a 3000×3000 pixel image at 300 DPI prints as a 10×10 inch photo, while the same image at 72 DPI prints much larger but at lower quality.
To convert image resolution for professional printing, set the DPI to 300. For web use, 72 DPI is standard. The image resolution converter also lets you upscale pixel dimensions — the HD image converter and 4K image converter increase both resolution and pixel count.
DPI metadata tells printers how many pixels to place per inch of paper. Changing DPI without changing pixel count just affects print size — no quality change. To actually increase detail, you need to upscale the pixel dimensions using interpolation or AI enhancement.

FAQ
Upload your image, set the target DPI to 300, and download. This changes the DPI metadata — for actual resolution increase, also increase the pixel dimensions.
Changing DPI alone only affects print size, not image quality. To increase actual detail, you need to upscale the pixel dimensions.
300 DPI is the standard for professional photo printing. 150 DPI is acceptable for large format prints viewed from a distance. 72 DPI is screen resolution only.
