Why convert JPG to PNG?

JPG (JPEG (Joint Photographic Experts Group)) — The most-used lossy format on the web. Excellent quality/size ratio for natural photos, but doesn't support transparency.

PNG (Portable Network Graphics) — Lossless format created in 1996 to replace GIF. Ideal for images with transparency, screenshots, logos, and illustrations.

Converting JPG to PNG typically reduces file size while preserving a visual quality close to the original. Beware: moving from a lossy format to a lossless one does not improve quality — it can actually inflate file size.
