About Resize Pages
Modufile's Resize Pages tool changes the dimensions of PDF pages to standard sizes (A4, Letter, Legal, A3) or custom dimensions. Content is scaled proportionally to fit the new size. The tool uses pdf-lib to modify MediaBox dimensions, and the entire process runs locally in your browser. This is useful when you need to standardize page sizes across a document, prepare a PDF for a specific printer, or convert between paper formats.
