What is DPI in images?
DPI (dots per inch) is a value stored in an image’s metadata that determines how densely it prints on paper. It does not change the image’s actual pixel quality.
Can I change DPI without affecting image quality?
Yes. Tools like ConvertDPI.com update the DPI metadata without altering the original pixels, keeping the image quality intact.
What DPI should I use for printing photos?
For professional-quality prints, use 300 DPI or higher. For web graphics, 72–96 DPI is sufficient.
Is DPI the same as PPI?
They are related but different. DPI refers to printer dots per inch, while PPI refers to pixels per inch on screens. For print, DPI is what matters most.
Which image formats support DPI conversion?
Common formats like JPG, PNG, TIF, BMP, and ICO support DPI adjustments.
