Extract images

A brochure, a product catalogue or a research paper often contains the only copy of a photograph you still need. Taking a screenshot of the page gives you whatever your screen resolution happens to be, which is rarely enough for print and always worse than the image already stored inside the file.

JPEG and JPEG 2000 data is copied out byte for byte, so the file you download is the image exactly as it was put into the PDF, with no second round of compression. Other pictures, the losslessly compressed kind that charts, logos, diagrams and screenshots usually are, are decoded in the browser and saved as PNG, so images from Word, Chrome and Hancom PDFs come out too.

A document drawn only with shapes and text, a vector PDF, has no pictures to extract: what looks like a figure may be lines and fills, and the tool then reports that no images were found. To turn whole pages into pictures, use PDF to Image instead. The copyright of extracted images stays with their authors, so mind how you use them.
