When you need a PDF as a picture
Some places take images but not PDFs. Social networks and messaging apps show images right in the feed or chat, while a PDF is just an attachment to tap on. Some upload forms only accept JPG for documents like a proof of payment or a certificate. Websites need images for previews and thumbnails. Converting the page to an image fixes all of these in a few seconds.
Each page becomes its own image, so a flyer, a poster, an event ticket or a single slide comes out as one picture you can post or send right away.
It's also useful the other way round: when a document arrives as a PDF but you want to include one of its pages in a presentation, a website or a design, an image is much easier to place than a PDF.
Pages or embedded photos
There are two modes. “Pages to JPG” takes a picture of every page as you see it, text, graphics and all. “Extract images” does something different: it copies the JPG photos already stored inside the PDF, without recompressing them, so you get the original product shots from a catalog or the photos from a report, not the whole page around them.
If “Extract images” finds nothing, the PDF probably stores its pictures in another format; use “Pages to JPG” instead.
JPG or PNG?
This page produces JPG, which is light and accepted everywhere, and is the right choice for pages with photos. If your pages are mostly text, charts or line drawings and you want perfectly crisp edges, use “PDF to PNG”, a separate tool that saves lossless PNG images at the same resolutions. PNG files are larger, so for sharing in chats JPG is usually more practical.
Choosing a resolution
72 dpi gives small images, enough for a thumbnail or a quick preview. 150 dpi is a good middle ground for screens, messaging and social posts. 300 dpi is for printing or for zooming into small print, and produces much larger files. If a form needs the image under a certain size, start at 150 dpi and then use “Compress image” with a target in KB if necessary.
Private, free and unlimited
The pages are turned into images by your own browser. The PDF isn't uploaded and nothing is stored. There's no sign-up, no limit on use and no watermark. Long documents at 300 dpi can take a while on a phone; if you only need a few pages, keep them with “Extract pages” first.
