Frequently asked questions
What is DPI?
DPI (dots per inch) is the print resolution — how many pixels print per inch. It only matters for printing; screens use pixel size.
Why does my image show no DPI?
Many images don't store a DPI value. Viewers then assume 72 or 96 DPI. The pixel dimensions still determine print quality.
What DPI is good for printing?
300 DPI is the standard for sharp prints. Divide an image's pixel width by 300 to get the largest good print width in inches.
Is my image uploaded?
No. The file is read locally in your browser.
