Convert PNG images to JPG online for free.

PNG files are typically 3-10x larger than the same image saved as JPG, because PNG uses lossless compression. For photographs, converting PNG to JPG shrinks the file by 60-80% with no visible difference on screens.
PNG is a lossless format, which makes it perfect for logos, icons, and images with transparency — but wasteful for photographs. A PNG photo stored on disk is typically 3-10x larger than the same image saved as JPG. Converting PNG to JPG shrinks the file dramatically while keeping quality visually identical for photos. The trade-off: JPG does not support transparency, so transparent PNG areas become white.

The converter decodes the PNG image and re-encodes it as JPG using libjpeg at 92% quality. Transparent pixels are composited onto a white background because JPG has no alpha channel. EXIF metadata is preserved from the source PNG. The output is typically 60-80% smaller than the source for photographs.
PNG to JPG conversion is lossy at 92% quality — visually indistinguishable from the source on screen and for print up to A3 size. The output is typically 60-80% smaller than the source PNG. Best results when converting photographs; screenshots and text-heavy images compress less and may show slight softening around text.
