Introduction
DPI (dots per inch) is the unit for print resolution. The DPI modifier adjusts the print resolution metadata of an image so it prints at the correct size and sharpness. Note: Changing DPI only modifies metadata — it does not change pixel count or actual image quality. Used primarily to meet print specifications (e.g., 300 DPI for high-quality printing, 72 DPI for screen display).

FAQ
Will the image look sharper after changing DPI?
No. DPI is just metadata and doesn't affect the image's pixel count or sharpness. Increasing DPI cannot make a blurry image sharper.
How much DPI do I need for printing?
Standard printing (A4 documents) needs 150-200 DPI. High-quality printing (posters, business cards) needs 300 DPI. Commercial printing needs 300-600 DPI.
Why does my printout come out the wrong size?
Print size = pixel dimensions ÷ DPI. For example, a 3000×2000 pixel image at 300 DPI prints at about 10×6.67 inches. If the size is wrong, verify that the DPI setting matches your printer settings.
