FAQ
- What is a PDF point? One PDF point equals 1/72 of an inch (approximately 0.353 mm). All standard page sizes in the PDF specification are defined in points.
- Why are the dimensions in decimal form? PDF pages are defined in points, and converting to inches, mm, or cm inevitably produces fractional values — these are rounded to two decimal places.
- Is my file uploaded anywhere? No — all processing happens entirely in your browser.
