Will JFIF lower the quality of my JFIF images?
+
A lossy source is already the result of one quantification pass, and any operation that has to re-encode adds a second. Where the job can be done without touching the pixel data we do that instead, and where it cannot you choose the quality factor yourself rather than getting a fixed default.
