How to resize PDF pages
Common when a document is stitched together from different sources — a phone-scanned photo mixed into an A4 report, or pages merged from two different printers.
1. Drop your PDF
Add the PDF with the mismatched page — the preview shows page one instantly.
2. Pick a size
Match the largest page automatically, or choose A4 / US Letter.
3. Resize & save
Every page is scaled to fit and centered — never stretched — then downloaded.
Mixed page sizes happen more often than you'd think: a cover page scanned at a different DPI, a photo dropped into a report, or pages combined from two different documents. This tool scans every page, works out the sizes already in use, and lets you normalize them to A4, US Letter, or whatever your largest page already is — without stretching a smaller page out of shape to fill the space. Everything runs locally with pdf-lib and pdf.js, so confidential documents never leave your device. See all PDF tools, including Organize pages if you also need to reorder, rotate or delete pages.
