Every page is placed on A4 paper, scaled to fit, ready to print or upload.
This tool changes the paper size of every page in a PDF — for example from a phone scan or Letter size to A4 — without turning the text into a picture.
Each original page is placed on a new page of the chosen size and scaled — "Fit" keeps the whole page visible with white margins, "Fill" covers the page and trims edges, "Stretch" fills exactly.
Text and vector graphics stay sharp because the pages are copied, not rasterised.

Yes. Pages are copied as PDF content, not as images.
Not much. To reduce the size use Compress PDF.
No. The PDF or card photos are processed inside your browser and never sent anywhere — safe for Aadhaar, PAN and other documents.
