About Resize PDF

PDF page size conversion ensures your documents match the requirements of different printers, display devices, or regulatory standards. Whether you need to convert US Letter documents to A4 for international printing or resize pages for a specific presentation format, our tool handles the transformation seamlessly.

The resize tool offers standard paper sizes used worldwide including Letter, Legal, A4, A3, A5, and more. You can also enter custom dimensions for specialized requirements like poster printing, banner creation, or digital display formats. The content scaling options let you choose how the original content fits within the new page size: scale to fit, center without scaling, or fill the page while maintaining proportions.

International businesses resize PDFs when collaborating across regions with different paper standards. Print shops convert customer files to match their equipment requirements. Architects resize drawings for different presentation contexts. Publishers adjust page sizes when preparing content for different publication formats or binding methods.

The resizing process preserves vector graphics, text searchability, and all interactive elements. Embedded fonts remain intact regardless of the scaling applied. For documents with mixed page orientations, you can choose to maintain the original orientation or standardize all pages. The output maintains professional quality suitable for printing or digital distribution.

Common Use Cases

  • Prepare documents for commercial printing requirements
  • Standardize page sizes across merged documents

How It Works

Our PDF resizer uses Ghostscript to transform page geometry while preserving content quality. Vector graphics are scaled without quality loss, and raster images are resampled using Lanczos filtering for optimal results. The tool supports all standard ISO and ANSI paper sizes.
