Resize PDF Pages
Change the page size of a PDF to A4, US Letter, Legal, A3, A5 or a custom size; content is scaled to fit. Free, private, in your browser.
Make every page the same paper size for printing or official submissions — for example US Letter to A4 or the other way round. The content of each page is scaled proportionally and centred, so nothing is stretched or cut off.
Resizing happens on your own device; your PDF is never uploaded.
How to use Resize PDF Pages
- Click “Choose PDF file” or drop your PDF onto the page.
- Choose the new page size — A4, US Letter, Legal, A3, A5 or a custom size in millimetres.
- Choose the orientation (or match each page) and an optional margin.
- Click “Resize pages” and download.
Features
- Common paper sizes plus any custom size.
- Content is scaled to fit and centred — never stretched.
- Keeps portrait and landscape pages, or forces one orientation.
- Rotated pages stay upright.
- No upload, no sign-up, no watermark.
Frequently asked questions
How do I convert US Letter to A4?
Open the PDF, choose A4 and click “Resize pages”. Each page is scaled to fit an A4 sheet and centred.
Will my content be stretched?
No. Content keeps its proportions; if the shapes differ, there is a little white space at the sides or top and bottom.
Are links and form fields kept?
Page content, text and images are kept. Clickable links, comments and fillable form fields are not carried over to the resized pages.
Are my files uploaded?
No. Your browser resizes the pages on your device.
