What's the difference between PDF to image and screenshot saving, and which should you choose?

The core difference between PDF to image and screenshot saving is: PDF to image renders the entire page, while a screenshot is just a raster copy of the visible screen area. If you need the whole page, batch processing, or a fixed resolution, choose PDF to image; if you only need a small portion of the screen and want speed, a screenshot is easier. Understanding the difference between PDF to image and screenshots helps you avoid the common pitfall of "blurry text when captured, and a mess when printed".
