What is DPI?
DPI (Dots Per Inch) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
DPI is used to describe the resolution number of dots per inch in a digital print and the printing resolution of a hard copy print dot gain.
Quick Tip
For web use, 72 DPI is sufficient. For printing, 300 DPI is the standard for most documents, while 600 DPI or higher is recommended for high-quality prints.
DPI Standards
| Use Case | Recommended DPI |
|---|---|
| Web Images | 72 DPI |
| Standard Printing | 300 DPI |
| High-Quality Printing | 600 DPI |
| Professional Photography | 1200+ DPI |
Frequently Asked Questions
Changing the DPI value alone doesn't affect the actual pixel dimensions or quality of your image. DPI is metadata that tells printers how to interpret the image. However, when you print an image at a specific size, a higher DPI will result in better quality.
DPI (Dots Per Inch) refers to the number of ink dots a printer can place within an inch. PPI (Pixels Per Inch) refers to the pixel density of a digital image. While technically different, these terms are often used interchangeably in digital imaging.
While you can change the DPI value of any image, increasing the DPI of a low-resolution image won't magically add more detail. The actual quality depends on the original pixel dimensions. For high-quality prints, you need both sufficient pixels and the right DPI setting.
Our DPI Changer tool supports JPEG, PNG, BMP, GIF, and TIFF image formats. The tool will preserve the original format unless you're converting from a format that doesn't support DPI metadata.
