A PDF built for one paper size doesn't always print or display well on another — a US Letter document opened on an A4-standard printer can end up with unexpected margins or clipped content. This tool rescales every page of an uploaded PDF to a chosen standard page size (A4, Letter, Legal, A3, or A5), scaling content to fit and centering it — never cropping or stretching out of proportion.
How it works
Upload your PDF and choose a target page size. Each page is scaled down or up to fit the new size while preserving its original aspect ratio and orientation (portrait or landscape), then centered on the new page. Download the resized file.
- Upload a PDF file.
- Choose a standard target page size.
- Generate and download the resized PDF.
Examples
Letter to A4
A US Letter-sized document is rescaled to fit A4, the standard size in most of the world outside North America, with content scaled and centered rather than clipped.
A4 to Legal
An A4 document is rescaled to fit the taller Legal page size, centered with even space above and below rather than stretched to fill the extra height.
Who should use it
- Converting a US Letter document to A4 for international printing or sharing.
- Standardizing a set of documents from mixed page sizes to one consistent size.
Industry applications
- International business and document exchange
- Print and publishing preparation
Advantages
- Preserves aspect ratio and orientation — no stretching or distortion.
- Supports all five common standard page sizes.
- No account, subscription or watermark.
Limitations
- Content is scaled as a whole page image position — it doesn't reflow text to better fill a very different page shape.
Common mistakes to avoid
- Assuming the resized PDF will have identical margins to the original — margins change slightly since the overall page proportions differ between standard sizes.
- Not checking the result on a mixed-orientation document, since each page is resized independently based on its own orientation.
Best practices
- Check both portrait and landscape pages in the output if your source document mixes orientations.
- Choose the target size that matches your actual printer or intended audience's regional standard.
Tips
- When sharing internationally, A4 is the more common default outside North America.
- Review the output on a multi-page document to confirm consistent results across pages.
