How it works
Each page is redrawn as a clear image and saved at the best quality that keeps the whole PDF 1 MB or less, and every page keeps its original paper size. Simple pages use less of the size budget, which leaves more for busy ones. If a page would become blurry, its resolution is lowered a little instead.
Good to know: the text in the new PDF is part of the page image, so it can't be selected or searched. That doesn't matter for form uploads, but keep your original file. For scans of certificates and mark sheets, “Black and white” gives a much smaller file. Password-protected PDFs need the password removed first.
