Resize PDF lets you change the page size of a PDF to A4, A3, A5, Letter or Legal. This guide explains each step, what to check and how to fix common problems.
What Is Resize PDF?
Resize PDF changes the paper size of every page, for example from Letter to A4. The content is scaled to fit the new page and kept in the middle, so nothing is cut off.
How to Use It — Step by Step
- Open this tool and choose your PDF (or drag and drop it onto the upload box).
- Pick the page size and choose Fit (keeps the shape) or Stretch (fills the page).
- Click Resize PDF and wait for the short in-browser step.
- Open the new PDF and check that every page looks right.
Why Use This Tool?
- Convert a US Letter document to A4 before you print it in India.
- Make all pages of a mixed-size PDF the same size.
- Scale a scan up to A3 for a poster print.
- No sign-up, no watermark and no payment.
- Processing happens in your browser, not on a server.
Supported File Formats
Resize PDF accepts: One PDF (.pdf). Output: One PDF named resized-<your file name>.pdf. Portrait pages stay portrait and landscape pages stay landscape.
Is It Safe and Private?
The processing code runs in your browser. The file is not sent to our servers. You can keep your original file, because the tool saves a new one.
Best Practices
- Keep a copy of your original file until you have checked the result.
- Check the output carefully before you share it.
- Test with a smaller, non-confidential file first if you are unsure.
