FAQ

What is the difference between DPI and PPI?

PPI (pixels per inch) refers to the density of pixels on digital screens, while DPI (dots per inch) refers to the printer dots per inch on physical paper. This tool adjusts both density metadata tags.

Does changing DPI reduce image quality?

No. When using 'Change Metadata Only', the pixel data remains 100% untouched and lossless while updating the printing density tags (JFIF/pHYs).

Which DPI is best for printing?

300 DPI is the industry standard for professional photo printing, books, and brochures. 600 DPI is ideal for fine art and detailed vector-like prints.
