PNG to JPG Converter

PNG (Portable Network Graphics) is a lossless format with an alpha channel, so it preserves sharp edges, flat color, and transparency perfectly — which also makes its files large for photographic content. JPG (JPEG) uses lossy DCT-based compression that discards detail the eye is unlikely to notice, trading some fidelity for much smaller files on photos and screenshots. This tool loads your PNG into an HTML canvas at its original pixel dimensions, then calls the browser's canvas.toDataURL with image/jpeg at a fixed quality of 0.92. Because JPEG has no alpha channel, transparency cannot survive the conversion. Before drawing your image, the tool fills the canvas with solid white and paints the PNG on top, so any transparent or semi-transparent pixels are composited against white rather than turning black. The conversion is one-way and lossy: re-saving as JPG permanently bakes in compression artifacts, most visible around hard edges, text, and flat color regions. For photos the difference is usually invisible; for logos, line art, or screenshots with crisp text, keeping the original PNG is often the better choice.
