Frequently asked questions
About Resize PDF
Resize PDF changes the page dimensions of a PDF. Use it when a document is the wrong paper size, a PDF made for Letter needs A4, a slide deck needs a standard page, or a label file has to match a printer template. Resizing is different from compression. Compression reduces file size. Resizing changes the page canvas and may scale the visible content. For print jobs, the important question is whether the content should fit inside the new page with margins or fill the page edge to edge. After resizing, always check a page with tables, page numbers, barcodes, and signatures. Small scaling changes can make a document print better, but aggressive resizing can make text too small or push content too close to the edge.
