    When do you need to resize a PDF?

    • A form or portal asks for A4 pages, but your PDF is Letter (or the other way round).
    • A PDF mixes page sizes (scans, receipts, slides) and you want it to print evenly.
    • You want a smaller A5 booklet, or an A3 poster from an A4 page.

    How it works

    Each page is scaled to fit the paper size you choose and centred on it. Nothing is cut off: if a page has a different shape, white space appears at the sides or at the top and bottom. Text and drawings are scaled, not turned into pictures, so they stay sharp and selectable.

    Orientation

    Auto keeps each page's direction: landscape pages go on a landscape sheet. Choose Portrait or Landscape to put every page the same way.

    Margin

    Add a small or large margin if your printer can't print to the edge.

    Resize, crop or compress?

    Resize changes the paper size. To cut away white margins, use Crop PDF. To make the file smaller in megabytes, use Compress PDF.

    Resize PDF: questions and answers

    Will my content be cut off?

    No. Each page is scaled to fit the new size and centred; nothing is cropped. If the shape is different, you'll see white space at the sides or at the top and bottom.

    Does resizing reduce quality?

    No. Text and drawings stay sharp and selectable, because the page is scaled, not turned into a picture. Links and form fields are not kept.

    What does Auto orientation do?

    Each page keeps its own direction: landscape pages go on a landscape sheet, portrait pages on a portrait sheet.

    How do I change a PDF from Letter to A4?

    Choose A4, keep Auto orientation, and click Resize PDF. Every page is scaled to fit A4 and centred.
