PDF Size Converter (A4 to US Letter)
Convert European A4 PDFs to US Letter size (and vice versa) to prevent your printer from cutting off the margins or throwing paper errors.
Fix International Print Errors
The US uses 'Letter' sized paper (8.5 x 11 inches). The rest of the world uses 'A4' (8.27 x 11.69 inches). If a European colleague sends you an A4 PDF and you send it to a US printer, the printer will often throw a paper mismatch error or physically cut off the top and bottom of the text. This tool mathematically rescales the PDF document's internal dimensions, ensuring it perfectly matches your local printer paper.
