JPG Converter

JPG is where photographs end up by default. Its compression discards detail the eye is unlikely to notice, so a camera shot fits in a few hundred kilobytes instead of tens of megabytes. That suits scenes built from gradients and texture. It suits screenshots and line art badly, because the discarded detail shows up as smudging around hard edges. Every re-save loses a little more, so keep an original if you plan to edit the file more than once.
