## Important Note

Krita can natively import PDFs with each page as a layer. You can simply open the PDF within Krita and then cut/copy/paste each later into a new image as appropriate or work with them as a single image.

The above approch with Krita can be significantly easier and less fiddly than the below.

## The original blog post...

If you have access to `imagemagick` you can quickly convert a PDF coloring page(s) to grayscale PNG using the below procedure and notes.


## Notes {#notes}

-   The `pdfimages` command below will get you a dpi listing for each page in the PDF that has an image, use that value instead of `300` in the below, **if** it is present.
-   The `-type Grayscale` parameter can be removed if you need color output.
- If the below fails Adobe has an online converter at: https://www.adobe.com/acrobat/online/convert-pdf.html


## Conversion {#conversion}

1.  Install `imagemagick`
2.  `pdfimages -list shipspage1.pdf`
3.  ``for file in `ls *.pdf`; do convert -density 300 -type Grayscale ${file} ${file}.png; done``
