DPI: Dots per inch (DPI) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch. The default DPI value in this form is 144. A value of 72 will output the same result as Acrobat when the zoom level is 100%. By increasing DPI to higher value it will produce larger sized JPG images with less loss in clarity.

JPG Quality: In this PDF to JPEG online converter (Open-source Engine only), you can set the JPG quality value according to the widely used IJG quality scale, which balances the extent of compression against the fidelity of the image when reconstituted. Lower values drop more information from the image to achieve higher compression, and therefore have lower quality when reconstituted.

About JPEG Image Format: JPEG (Joint Photographic Experts Group) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
