Change PDF Page Size

Put every page of a PDF on A4, Letter, Legal, A3, A5 or a size you choose. Content is scaled and centred as vector graphics, so text stays sharp and selectable. Everything happens in your browser.

Will this work for my PDF?

Letter, Legal or odd-sized pages that must be A4 (or the reverse)

Every page, or a range, is scaled onto the new size and centred. Text stays vector.

Mixed page sizes, rotated or cropped pages

Each page is placed upright as your viewer shows it; automatic orientation matches landscape pages to landscape paper.

A fillable form or a PDF with comments

Form fields, comments and links are removed from changed pages. Flatten first to keep answers on the page.

When you need a different page size

Portal uploads

Government, exam and job portals often accept only A4. Convert Letter or odd-sized PDFs first.

Printing

A US Letter document printed on A4 gets cut off or shrunk unevenly. Convert it so it prints cleanly.

Scans and phone PDFs

Scanners and apps produce odd page sizes. Put every page on the same paper size.

Choosing the right options

Fit, fill or actual size?

  • Fit shows the whole original page, scaled down or up. Letter to A4 leaves thin white bands at the top and bottom, because the shapes differ.
  • Fill scales until the new page is covered, so there are no white edges, but a little of the original edges is trimmed.
  • Actual size keeps 100% scale and centres the page. Use it to put a small page on bigger paper without enlarging it.

Page size is not file size

This tool changes the paper dimensions (A4, Letter). It does not make the file smaller in KB or MB. For that, compress the PDF or compress it to an exact size like 100 KB or 200 KB.
