Resize PDF Pages
What is this tool?
A PDF page resizer built on pdf-lib. It places each page onto a sheet of the size you choose, centred, and either fits the whole page inside, fills the sheet, stretches to it, or keeps the original size. Orientation can follow each page or be fixed.
When to use it
- Converting a Letter-size PDF to A4 (or the other way round) before printing
- Making every page of a mixed-size document the same size
- Enlarging a small-format PDF to A4 or A3
- Preparing a PDF for a printer that wants a particular size
- Setting an exact custom page size in millimetres or inches

Frequently asked questions
What is the difference between Fit, Fill and Stretch?
Fit keeps the whole page and adds blank space; Fill covers the sheet and cuts off the overflow; Stretch matches the sheet exactly and distorts the page.
Do links and form fields survive?
No. Pages are redrawn onto the new sheets, so links and fillable fields on the originals are not carried over. Flatten forms first if you need their values.
Can I keep portrait and landscape pages as they are?
Yes — Match each page keeps every page's own orientation.
Is my PDF uploaded?
No — it's processed entirely in your browser.
