Why convert PNG to JPG?
PNG files can become very large, especially for photographs. A 5 MB PNG can often become under 500 KB as JPG without visible quality loss. This makes JPG the standard choice for photos on the web, in email and on social media. The difference is because JPEG uses lossy compression that removes information the eye barely sees. PNG saves every pixel exactly, which requires more space. For photographs and images with soft tones you rarely notice any difference. Important to know: JPEG does not support transparency. If your PNG has transparent areas, these are filled with a background color (default white). In the tool you can choose which color to use — this can make a big difference depending on the image appearance. All processing happens in your browser. Images are never sent to any server, making it safe to convert sensitive images.
