Frequently asked questions
Does PNG recover detail already lost in a JPEG?
No. PNG preserves the decoded pixels without adding another lossy JPEG generation; it cannot reconstruct discarded detail.
Will converting a JPEG create transparency?
No. A JPEG has no alpha channel. Converting it to PNG does not automatically remove its background.
