What to know

DPI is metadata about physical print size; this tool does not add pixels or improve sharpness. The image is re-encoded, so EXIF, colour profiles, or some quality may be lost. JPG output puts transparency on white. Maximum 20 MB, 8 megapixels, and 8192 pixels per side.

Frequently asked questions

Will 300 DPI make a blurry image sharper?

No. Pixel dimensions do not change, so no extra detail is created.

Why does another app show a different print size?

Some apps ignore DPI metadata or apply their own layout settings. Check the final print setup.
