Convert PDF to JPG

Size and sharpness

A PDF page is measured in points, 72 to the inch, so the dots-per-inch setting decides how many pixels each page gets. The default, 150, is sharp on any screen and keeps files small; 300 matches ordinary print; 72 makes thumbnails. Anything from 36 to 600 can be typed in.

JPG and WebP pictures are saved at 92% quality on a white background. PNG keeps every pixel and is drawn without a white fill, so parts of a page the PDF leaves unpainted stay transparent; most pages paint their own white, and look the same. For reading tiny print or printing a page large, the PDF itself stays the sharper choice, since its text has no pixels at all.

Picking pages

The Pages box takes single pages and ranges, separated by commas: 1 gives the cover, 2-5 four pages, 1-3, 7, 10-12 seven pictures. Page numbers count from the first page of the file, whatever is printed on the page itself. A range beyond the end of the document is simply ignored, and the Convert button waits until the box holds something it can read.

The pictures are named after the PDF with the page number, zero-padded so they sort in order: report-01.jpg, report-02.jpg. Unzip the result in File Explorer with Extract all. To cut the pages out as PDFs instead, see extract pages and split PDF.

What goes into the pictures

Each page is drawn as it is saved in the file: its text, pictures, turned pages and what has been saved into it. Marks you have added in the PDF Editor but not yet saved, such as a signature or a highlight, are not in the file, so save the PDF first and convert the saved copy.

Pages that were photos to begin with, such as a scan or a JPG turned into a PDF, come back at the size the dpi gives them, not at the photo's original size; keep the original photos if you need them full size. The words in a picture cannot be selected or searched; image to text reads them back out if you need them.

Why turn PDF pages into pictures

• Slides and documents that take pictures but not PDFs. Octoolo's Presentations and Documents both insert pictures.
• Chats and social posts, where a picture shows in the conversation and a PDF is only an attachment.
• Upload forms that want JPG, as some application and ID portals do.
• A preview image of a brochure, a menu or a flyer for a website; WebP at 150 dpi is the lightest choice.
• Cover thumbnails for an online listing of e-books, sheet music or courses you sell as PDFs: convert page 1 only.
• Printing at a photo kiosk or on a printer that only takes pictures from a USB stick: use 300 dpi.

Need the opposite? JPG to PDF makes a PDF from pictures. To resize or crop a page picture afterward, use the image resizer or crop image.
