Does changing DPI change my image quality?

No. DPI is just a print-density tag. We rewrite only that tag — your pixels are untouched.

Why do print shops ask for 300 DPI?

300 dots per inch is the standard for sharp printed output. This tool sets that tag so their software accepts your file.

Set the print DPI of a JPEG or PNG without re-encoding — pixels and quality stay untouched.
