What this does
Each page is placed onto a fresh A4 canvas, scaled proportionally so nothing is stretched or cropped. Pages that are already A4 are left exactly as they are.
When you need it
Many submission portals — especially outside the US — require A4 specifically. This matters if your document was created on US Letter paper (common in PDFs from the US) or scanned at a non-standard size.
Privacy
Page resizing happens locally in your browser. Nothing is uploaded.
Frequently asked questions
