Change the DPI of an image for printing
Some print shops and forms ask for 300 DPI. Choose your JPG or PNG images, enter the new DPI and download them without losing quality.
DPI tells a printer how large to print a picture; it does not add detail. A small low-resolution photo will still look soft when printed big, so start from the largest original you have.

Questions
Does changing DPI make the photo sharper?
No. DPI only sets the printed size. A sharper photo needs more pixels.
Why isn’t WebP supported?
WebP has no standard place to store DPI.
What DPI should I use for printing?
300 DPI is the usual choice for photos and documents.
Does a higher DPI make the picture sharper?
No. It changes the print setting, not the amount of detail.
