PDF Page Resizer

Change a PDF to A4, A3, A5, Letter, Legal or Tabloid. Pages are scaled and centred without stretching so everything prints correctly.

PDF Page Resizer changes every page of a PDF to a standard paper size such as A4, A3, A5, Letter, Legal or Tabloid, scaling and centring content so nothing gets stretched. It solves the common problem of a PDF letter to A4 mismatch, where a document created for one paper standard prints incorrectly or gets cropped on a printer set up for the other.

Rather than distorting the aspect ratio to force-fit a new page size, the tool scales each page proportionally and centres it on the new sheet, keeping everything readable and correctly proportioned. Mixed documents with both portrait and landscape pages are also handled, keeping each page's own orientation intact if you choose to preserve it.

How to use the PDF Page Resizer

  1. Upload the PDF you want to resize.
  2. Select the target paper size — A4, A3, A5, Letter, Legal or Tabloid.
  3. Choose whether to keep each page's original orientation or force a single orientation.
  4. Preview how the pages will be scaled and centred on the new size.
  5. Click Resize and download the converted PDF.

Why use this tool

Proportional scaling, no stretching

Pages are scaled evenly and centred on the new sheet size, so the aspect ratio always stays true to the original content.

Covers all common paper standards

A4, A3, A5, Letter, Legal and Tabloid sizes are all available, covering the most frequent size mismatches between regions.

Handles mixed orientation documents

A Keep Original option places each page on a sheet matching its own portrait or landscape orientation rather than forcing all pages the same way.

Fixes printing problems at the source

Resizing the PDF itself avoids relying on a printer's own scale-to-fit setting, which doesn't always produce consistent results.

Common use cases

How centring and scaling work

Each page's content is scaled by the same factor in both dimensions to preserve proportions, then centred within the new page size, leaving even margins rather than stretching content to fill the new sheet's edges exactly.

Choosing keep original vs a single orientation

Keep Original places each page on a sheet matching its own portrait or landscape layout, useful for documents mixing both. Forcing a single orientation instead standardises every page the same way, better for documents intended to be printed and bound uniformly.

PDF page resizer vs printer scale settings

Relying on a printer's fit-to-page option can crop or shrink content inconsistently between printer models. Resizing the PDF file itself produces one fixed, predictable result regardless of which printer or reader opens it.

Checking the result before printing

Always preview the resized PDF at 100% zoom before printing a physical copy, to confirm margins and scaling look correct, particularly for documents with fine print or small diagrams near the page edges.
