This Is A Test - PNG vs. JPEG

PNG is a lossless format, so it’s always going to be much larger in file size. But by its nature it will also be as close to the original as possible.

For this kind of image, though, with a lot of color gradation, the visible difference is minuscule, especially if the JPEG is saved at a high quality, and the JPEG file will be a lot smaller.

PNG images really work much better with line art, or images with lots of solid colors. And the real advantage of PNG files, for web design anyway, is that they have a true alpha channel for transparency.

For putting photos on the web, JPEG is almost always going to be the better choice in terms of the tradeoff between file size and image quality.
