Resize PDF Pages
Change PDF page dimensions to Letter, A4, A3, Legal, or custom sizes.
Key Capabilities
Five standard presets, or custom dimensions
A4 (210x297mm), Letter (215.9x279.4mm), Legal (215.9x355.6mm), A3 (297x420mm), A5 (148x210mm), or type an exact width and height in millimetres.
Scales proportionally
Content is scaled to fit the new page size — nothing is stretched unevenly or cropped off.
Keeps text and vectors sharp
Because it's a scale operation and not a rasterize-and-resize, text stays crisp at the new size.
