How to Pull One Chart or Page Out of a PDF as an Image

To get one chart out of a PDF as an image, open PDF to JPG, drop the PDF, type the page number in the Pages field under More options, and convert. One selected page gives you one image file, downloaded directly, not a zip. If you want only the chart and not the whole page around it, crop that image afterwards. That is the whole job; the rest of this page is the details that make the result look right on a slide.

Find the right page number

After you drop the file, each page appears as a small preview labelled Page 1, Page 2 and so on, so you can find the chart by eye instead of guessing. Use that number, not the number printed in the report's footer: a report with a cover and a contents page often has its printed page 5 on PDF page 7.

Select only that page

Open More options and type the page into the Pages field. An empty field means every page. The field takes single pages and ranges, separated by commas, as in its own example: 1-3, 5, 8-10. An open range such as 8- runs to the last page. If what you type matches no page in this PDF (for example 40 in a 12-page file), a note under the field says so and warns that every page will be converted instead, so read it before you click.

With one page selected, the result is one file named after the page, such as page-007.jpg, and it downloads on its own. Select two or more and you get pdf-pages.zip instead, and each page's preview also gets its own download button.

Pick a resolution that survives a slide

The Resolution slider runs from 72 to 300 DPI and starts at 150. A chart with small axis labels needs more pixels than a page of body text, so for a figure you plan to show on a projector or zoom into, move it up toward 300. The tool shows the pixel size each page will come out at before you convert. Whatever the slider says, the long edge is capped at 4000 pixels, which keeps a very large page from running the browser out of memory.

Choose PNG instead of JPG for a chart with flat colours and thin lines: JPG (saved here at quality 0.9) can leave faint smudges along sharp edges, while PNG keeps them clean at the cost of a bigger file. For a page that is mostly a photograph, JPG is the smaller and perfectly good choice.

Crop it down to the figure

The output is the full page. To keep only the chart, drop the image into Image crop, choose Free or the ratio your slide uses, draw the box around the chart and its caption, and crop. Leave a small margin around the axis labels; a crop tight to the bars usually cuts off a number.
