About this tool
Change the DPI value stored in an image's metadata — useful for print shops, passport photos, and documents with strict print-resolution requirements.
Frequently asked questions
Does changing DPI resize or change the quality of my image?
No — DPI is just a metadata tag describing intended print density; the actual pixel dimensions and image data stay exactly the same. It only affects how large the image prints, not its on-screen appearance or file quality.
What DPI should I use?
300 DPI is the standard for most print jobs (photos, documents); some passport/ID photo specs or professional print shops require a specific value — check your requirement and enter it directly.
