About the PDF Page Size Converter

PDF Page Size Converter places every source page onto A3, A4, A5, Letter, or Legal paper in portrait or landscape orientation. A preview shows the first source page fitted inside the target dimensions.

Each page is scaled proportionally and centred with blank margins when aspect ratios differ. Source pages are embedded as PDF content, so text and vectors remain intact rather than becoming screenshots.

The tool does not crop, stretch, add bleed, or enlarge content beyond the proportional fit. Very different source sizes can produce noticeably different margin widths.
