Increase DPI of Image FAQs
Does increasing DPI make my photo sharper?
No. Updating DPI metadata does not create missing visual detail. Resampling changes pixel dimensions but cannot recover original detail.
Does the exported file store real DPI?
Yes, PNG physical-pixel metadata and JPEG JFIF density are written to the exported file.
What should I use for printing?
Many print workflows use 300 DPI, but requirements depend on your printer and intended print dimensions.
