About PDF Format Modifier

PDF Format Modifier changes the page dimensions of any PDF to a standard paper size — A3, A4, A5, Letter, or Legal — in portrait or landscape orientation. Content is scaled proportionally to fit the new page size, with configurable margins. All processing runs in your browser using pdf-lib; no file is uploaded anywhere.
