Printers, copy shops, government offices, and universities around the world expect documents in A4 — a PDF created in US Letter or US Legal format will print with awkward margins, get cut off, or be rejected by systems that require A4. Converting a PDF to A4 size solves this instantly: every page is resized to the exact A4 dimensions, and the content is scaled proportionally so nothing is cropped or distorted. This is essential when submitting forms and applications internationally, printing US documents on A4 paper, or standardizing page sizes across merged documents. Our converter changes the actual page dimensions of the PDF (not just the print settings), so the resulting file is a true A4 document that works everywhere. ## Convert Legal to A4 PDF **US Legal (8.5 × 14 in)** pages are longer than A4, so legal documents, contracts, and court filings often need conversion before they can be printed or filed internationally. This tool handles **Legal to A4 PDF conversion** automatically: upload the PDF, keep the default "Fit" scaling, and every Legal page is scaled down proportionally onto an A4 page. The same applies to **Letter to A4**: US Letter (8.5 × 11 in) is slightly wider and shorter than A4, and the Fit mode adjusts the content so it fits the A4 proportions perfectly. Because the conversion uses PDF-level vector transformations, text stays selectable and sharp — the result looks like the document was created in A4 from the start. ## Need to Automate?
