How to Change PDF Page Size

1
Upload your PDF
Drag your PDF onto the tool or click to browse. The file never leaves your device - all resizing happens locally in the browser.
2
Choose the target page size
Pick A4, US Letter, US Legal, or enter custom width and height in millimetres or inches. A preview shows the new page dimensions.
3
Download the resized PDF
Click Resize. The tool scales all page content to fit the new dimensions and delivers the finished PDF as an instant download.

Mismatched page sizes cause headaches at the print shop and in document management systems. PDFsuite lets you standardise every page in a PDF to A4, US Letter, Legal, or a custom size - in your browser, without uploading anything. The WebAssembly PDF engine scales all vector graphics, fonts, and raster images proportionally so the layout looks intentional rather than stretched.

The most common use case is converting a US Letter PDF to A4 for European printing, or vice versa. The tool scales content to fit within the new page boundary while preserving the original aspect ratio and adding small margins where needed. Custom dimensions let you target non-standard formats like B5, executive paper, or a specific envelope size - just enter width and height directly.

Running offline in the browser means your documents stay private. Financial reports, design files, and legal contracts are resized entirely on your machine with no server involvement. Because the tool is browser-based, there is nothing to install, and file size is limited only by what your device can handle in memory.

Common questions

Will resizing a PDF distort the content?: No - content is scaled proportionally to fit the new page size. If the aspect ratio of the source and target differ, the tool centres the content and adds small equal margins rather than stretching. Text remains crisp because PDF vector content is resolution-independent and scales without quality loss.
Can I convert just some pages rather than the entire document?: The current tool resizes all pages in the document to the same target size in one pass. To resize only specific pages, first use the Extract Pages tool to pull out the pages you need, resize that subset, then use Merge to recombine the document.
Does changing page size affect file size?: Usually not significantly. The PDF content streams are scaled but not re-encoded, so embedded images remain at their original compression and resolution. If you need to reduce file size as well, run the Compress tool on the output after resizing.
