Does changing DPI change image quality?
No. DPI is just a number stored in the file that tells printers how big to print it. The pixels are untouched.
How do I get a 300 DPI image?
Set 300 DPI here. To print sharp at 300 DPI, the image needs enough pixels: a 10 × 15 cm print needs about 1181 × 1772 px.
Why is my 300 DPI image printing small?
Print size = pixels ÷ DPI. A higher DPI makes the same pixels print smaller (and sharper).
Are my images uploaded?
No. Everything happens in your browser.
