Limitations
Runs entirely in your browser. Numeric calculations use IEEE-754 floating-point arithmetic; displayed values are rounded to 15 significant digits unless stated otherwise.
This calculates dimensions; it does not alter image metadata or create detail. PPI is used for raster sizing; printer DPI may describe a different device property.
