Change all pages to a standard paper size like A4 or US Letter.
Resizing a PDF changes the physical page dimensions — for example, scaling an A3 document to A4, or changing a letter-size PDF to a custom size. This is different from compression — it changes the page geometry rather than the file encoding.
Print shops resize submitted PDF artwork to match their standard paper sizes. Architects scale A1 blueprint PDFs down to A4 for email distribution. Teachers resize oversized presentation PDFs to standard A4 for printing handouts. Anyone preparing documents for specific paper sizes benefits from PDF resizing.
Choose from preset page sizes (A4, A3, Letter, Legal) or enter a custom width and height in millimetres. Content is scaled to fit the new dimensions while maintaining aspect ratio. Processing runs locally in your browser.
Your files never leave your browser. No account required, no server uploads — just fast, local processing. This is what it means to resize PDF pages without uploading.
Make an irregularly sized PDF fit perfectly on A4 paper.
No, content is scaled down to fit within the new page dimensions.
