Plenty of places accept images but not PDFs: social posts, chat groups, slide decks, blog articles and the attachment fields of some online forms. Converting each PDF page to an image is the easiest fix, and it lets phone users see the content without opening a PDF reader. This tool renders every page of the PDF as an image and bundles them into one ZIP download, named by page number as page_1, page_2 and so on, so they are easy to use in order.
Choose PNG or JPG. PNG is lossless, giving the sharpest text edges, table lines and icons, and suits documents, charts and anything you will edit further. JPG is compressed at 0.92 quality and produces much smaller files, which suits photo-heavy catalogs or pages you simply want people to view. There are three scale options, 1.0, 1.5 and 2.0, with 2.0 as the default. Scale 1.0 is roughly the size of a 100% on-screen view; 2.0 doubles width and height, so text stays crisp on high-density screens and when zoomed, at the cost of larger files.
To estimate pixel sizes, remember that PDF measures in 1/72 inch. An A4 page is about 595 × 842 pixels at 1.0 and about 1190 × 1684 at 2.0; US Letter is 612 × 792 at 1.0. For printing, use the highest scale with PNG. Large page counts use more memory during rendering and zipping, so converting hundreds of pages on a phone can be slow; split out the pages you need first with our PDF splitter.
Password-protected PDFs ask for the open password first. All rendering and zipping happens in your browser and files are never uploaded. To go the other way and combine images into a PDF, use our image to PDF tool.
