Change PDF page size for printing and consistent layouts
PDFPA Resize PDF changes the page dimensions of an existing PDF without requiring a desktop publishing application. Use it when a document needs to match a printer paper size, a submission requirement or a consistent page format across selected pages.
Convert PDF pages to standard paper sizes or custom dimensions
The resize workspace includes A4, A3, A5, Letter and Legal presets for common document workflows. When those sizes do not match the destination, choose Custom and enter the required width and height in millimeters. Portrait and landscape controls make it possible to define the target orientation separately from the original document.
You can apply the new dimensions to the complete PDF or only selected pages. Unselected pages retain their original size, which is useful when a document contains a special cover, foldout page or mixed-size appendix that should remain unchanged.
Choose how original content fits the new page
Fit keeps the source page proportions and centers the content within the target dimensions, so blank margins may appear when the aspect ratios differ. Stretch fills the entire target page but can change content proportions. Choosing between the two lets you prioritize visual fidelity or full-page coverage depending on the document.
Resize PDF currently requires no account or subscription and has no daily resize quota. Each job accepts one PDF up to 200 MB and up to 2,000 pages, with normal anti-abuse protections still applying. Completed results are temporary and normally remain available for up to 10 minutes before automatic cleanup.
