Change the Page Size of a PDF
Upload one or more PDF files and choose a paper size: A4, A3, A5, Letter or Legal. Every page is changed to that size, and its content is scaled to fit, without being stretched, and centred. It's the quickest way to make a PDF with mixed page sizes uniform, or to turn US Letter pages into A4 for printing.
The content stays vector — text remains sharp and selectable, and links move with the content. You can keep each page's orientation, or make all pages portrait or landscape, and add a margin around the content. Files are kept for 48 hours and then deleted automatically — or you can delete them yourself at any time.

Frequently Asked Questions
Is resizing PDF pages free?
Yes, changing the page size of your PDF files is completely free.
Will the content be stretched?
No. The content keeps its proportions: it is scaled until it fits the new page (inside the margin you set) and centred, so a page with other proportions gets empty space at the sides or at the top and bottom.
What does “Keep each page's orientation” mean?
Portrait pages become portrait A4 (or the size you choose) and landscape pages become landscape A4. Choose “Portrait” or “Landscape” to give every page the same orientation.
Is my file kept private?
Files are transferred over an encrypted connection and processed on our server. Uploaded files and results are stored for 48 hours, so you can download the result via its link, and are then deleted automatically. You can delete them yourself at any time with the delete button in the “Your files” list.
Is there a file size limit?
Yes, uploaded PDF files must be 1 GB or smaller.
