Resize PDF Pages to Any Dimension Online
How to Resize PDF Pages
Need to change a PDF from Letter to A4, shrink an oversized scan, or standardise page dimensions across a multi-page document? This tool lets you resize PDF pages to any standard or custom size while controlling how the content is scaled to fit.
Resize a PDF in Three Steps
- Upload your PDF using the file picker above.
- Choose a target size — select A4, Letter, Legal, A3, A5, or enter custom width and height in inches or centimetres.
- Pick a content scaling option (proportional, margin-preserving, or none) and click Resize Page.
Content Scaling Options Explained
Scale Proportionally fits the entire page content within the new dimensions without distortion — best for converting between similar aspect ratios like Letter and A4. Preserve Left/Right Margins and Preserve Top/Bottom Margins keep one axis fixed while scaling the other. None changes only the media box, leaving content at its original size and position.
You can resize all pages or target specific pages using ranges like 1,3,5-8. Use the
visual preview to compare the original and target sizes before processing.
About Page Resizing
This tool changes the dimensions of selected pages within your PDF document.
- Specify page numbers or use "all" to resize every page.
- You can enter width and height in inches or centimeters; values are converted to points automatically.
- Use orientation to flip the target page between portrait and landscape without retyping dimensions.
- Content scaling lets you center pages, scale proportionally for wider/narrower targets, or keep margins steady on a single axis.
- None: keeps the original content size while the media box changes.
- Preserve Left/Right Margins: scales content uniformly from the left and right so horizontal margins stay proportional.
- Preserve Top/Bottom Margins: scales content uniformly from the top and bottom to maintain vertical balance.
- Scale Proportionally: scales the page uniformly so that both the width and height fit inside the selected media size.
Tips for Best Results
- Use standard page sizes like A4 or Letter for compatibility
- Choose Scale Proportionally to avoid content distortion
- Preview the size comparison before processing
- Use page ranges to resize only specific pages
