Frequently Asked Questions
Is this converting a PDF?
No. It calculates page dimensions.
Which sizes are included?
A-series, Letter and Legal are included.
Choosing a page size and DPI
A4 is standard in most of the world, and Letter is standard in the United States and Canada. The tool converts the physical size into pixels at your chosen DPI, which helps when you build images or documents for print.
Use 300 DPI for print-quality output and 72 to 96 DPI for screens. This is a calculator, not a PDF editor, so it does not change any file.
