Frequently Asked Questions
PNG files are typically much larger than JPG files because PNG uses lossless compression. Converting to JPG with appropriate quality settings can significantly reduce file size while maintaining acceptable image quality. This is especially useful for web images where file size affects loading speed.
No, JPG format does not support transparency. Any transparent areas in your PNG will become white (or the background color) in the JPG output. If you need to preserve transparency, keep the image in PNG format or use a different format like WebP.
File size reduction depends on the image content and quality setting. Typically you can achieve 70-90% size reduction when converting PNG to JPG. Complex images with lots of colors will compress less than simple images. The tool shows you the exact size difference for your specific image.
