How to Use PDF Page Size Changer — Custom Dimensions Tool
How to Use the PDF Page Size Changer:
Upload Your PDF: Click the upload area or drag and drop your PDF file. Files up to 50 MB are supported.
Choose a Target Page Size: Select the desired output size from the dropdown — A4, Letter, Legal, A3, A5, Tabloid, or Executive.
Select a Fit Mode:
- Scale to fit — scales content proportionally so it fits within the new page, adding thin margins if the aspect ratios differ. Best for most documents.
- Scale to fill — scales content proportionally to fill the new page; edges may be slightly cropped if aspect ratios differ.
- Stretch — stretches content to exactly fill the new page regardless of proportions. May distort text or images.
- Centre — places the original content centred on the new page without any scaling. Useful when changing from a slightly different size.
Match Source Orientation (optional): When checked, landscape source pages are given a landscape target page. Uncheck to always use the portrait dimensions of the target size.
Resize Pages: Click "Resize Pages". Each page is processed in your browser — no data is sent to any server.
Download: Click "Download Resized PDF" to save the result.
