How to: Resize PDF
- Select your PDF.
- Pick the target size.
- Download.
PDFs assembled from different sources often have pages of different sizes, which looks messy and prints badly. Resizing makes every page the same paper size while keeping content sharp.
Common uses
- Make a merged PDF consistent before printing or binding.
- Fit phone scans and receipts onto standard pages.
- Normalise pages before creating a booklet.
Tips for best results
- This changes paper size, not file size.
- Check landscape pages – they are fitted into the new size.
Common paper sizes
A4 (210 × 297 mm) is standard in most of the world; US Letter (8.5 × 11 in) and Legal (8.5 × 14 in) are used in North America. A3 is common for drawings and A5 for booklets.
Resize vs compress
Resizing changes the physical page dimensions; it does not shrink file size. To reduce megabytes, use Compress PDF.
