A PDF resizer is a tool that lets you change the physical dimensions of a PDF's pages. This is different from compressing a PDF, which reduces file size without changing the page dimensions. Resizing is essential for a variety of tasks, from converting a large-format engineering drawing to a standard A4 size, to making sure a document fits a specific digital display or a printer's paper tray.
Our online PDF resizer gives you complete control. You can choose from common paper sizes like A4, Letter, and Legal, or you can enter precise custom dimensions in millimeters, inches, or pixels. The tool also provides intelligent scaling options to ensure your content looks great on the new page size, so nothing is cropped or misplaced.
Our free online tool offers a simple yet powerful way to change your PDF's page size without installing any software. Here’s what makes it stand out:

Resizing changes the physical dimensions of a PDF's pages (e.g., from A3 to A4), which may or may not affect the file size. Compressing reduces the file size by optimizing and reducing the quality of elements within the document, without changing the page dimensions. If your goal is a smaller file, you should use our Compress PDF tool.
Resizing primarily changes the page canvas. However, depending on your chosen scaling option, the content can be adjusted. "Fit to Page" scales the content to fit the new dimensions while preserving the aspect ratio, whereas "Stretch to Fit" changes the aspect ratio to make the content fill the entire page.
