PDFs or portable document files are a good way to share information online because there are lightweight and compact. More importantly, PDFs will display information to the recipient in the format defined by the author. It's not like a .DOC file that will require the reader to have fonts and other formatting features on his computer in order to view the document.
PDF files can also contain pictures and images. In most cases, these images cannot be extracted directly from the PDF reader itself. However, if you need to take an image from a PDF file, you can easily make a screenshot using your Operating System, and then crop it using a photo editing software.
On a Mac
Cropping photos from a PDF file on the Mac is easy. You have several ways to do this. First, you can take a snapshot of the image, which is automatically saved as a PNG file.
- Open the PDF file you want to get the picture from.
- Scroll through the file such that the image is in full view.
- Press CMD-SHIFT-4. Your cursor will change into a crosshair or "target" like image.
- Drag your cursor from one corner of the image to another. You will hear a snapshot-like sound, like a camera shutter taking a picture.
Your image will now be saved on your desktop as a "Picture X.PNG" where "X" is the numerical sequence in which the snapshot was taken. You can rename this to any other name you wish. PNG files are, by default, viewable on web browsers, so you can directly use this online if you wish.
