About Resize PDF

PDFs come in different page sizes, and a mix of them can cause trouble when you print or submit a file. This tool lets you resize PDF pages online for free. Pick a page size such as A4, Letter, Legal, A3 or A5, and every page is changed to it. The content is scaled to fit and centred on the page.

Pages are scaled, not turned into images, so text stays real and does not go blurry. Nothing gets cut off, because each page is scaled up or down to fit the new size.

It suits anyone who has to hand in a document in a set paper size. Say a student in the UK gets a reading pack from a US university in Letter size, but the school printer and the course portal both expect A4. She opens the file here, picks A4, and clicks Resize PDF. The work happens in your browser, and the file is never uploaded.

How to use Resize PDF

  1. Drop your PDF on the page or click Choose file.
  2. Pick a Page size: A4, Letter, Legal, A3 or A5.
  3. If you like, choose a Direction: Like each page, Portrait or Landscape.
  4. If you like, choose a Margin: None, Small or Wide.
  5. Click Resize PDF. Each page is scaled to the new size.
  6. Download the resized PDF, or click New file to start again.
