Centered geometry may produce fractional pixels. This tool does not crop files or include a printer's extra borderless enlargement.

How it works

Compare the image and paper aspect ratios. Filling the paper may crop the image; fitting the whole image may leave borders. PPI = pixels along a printed dimension ÷ that dimension in inches. Changing a PPI metadata tag alone does not add image detail.

Scope & limitations

The centered continuous geometry can produce fractional pixels; an image editor may require whole pixels. The site never reads or crops your file and cannot locate people or important subjects. Borderless printer enlargement, cutting tolerances, sharpness and viewing distance affect the final print. PPI is not a quality guarantee; check the print supplier’s preview.
