Documents assembled from several sources often mix paper sizes, which prints badly and looks careless. Resizing normalises every page to one size, scaling each to fit and centring it rather than stretching it out of shape.

How to resize a PDF to A4 or another paper size

1Upload the PDF.
2Choose A4, Letter, Legal, A3 or A5, portrait or landscape.
3Download the resized document.

Questions people ask

Will my content be distorted?

No. Each page is scaled proportionally and centred, so nothing is stretched. A page with a different shape gets even margins instead.

Does the text stay selectable?

Yes. Pages are placed as PDF content, not flattened into images, so text stays text.

Which sizes are supported?

A3, A4, A5, US Letter and US Legal, in portrait or landscape.

The PDF toolkit that reads your documents too

Doclium is a free web app for working with PDFs: merge, split, compress, rotate, protect and convert them in your browser, with no install and no signup to start. Where most PDF tools stop at the file, Doclium also reads it — ask a question and get an answer that cites the page it came from, so you can check it.

Chat with a PDF, summarise a long report, or translate one into another language. Clean documents up with OCR, redaction, watermarks, headers and footers, page numbers and A4 or Letter resizing. Every change can be undone, and every export is previewed before it downloads.

Private by default Your library is yours alone. Documents are scoped to your account or device and are never readable by another user.

HTTPS everywhere All traffic is encrypted in transit with TLS. Your files are not used to train AI models.
