Frequently Asked Questions
What happens to transparent areas when converting PNG to JPG?
Because the JPEG format does not support alpha transparency, our converter fills transparent pixels with your selected background matte color (white by default) instead of turning them black.
Why convert images to WebP?
WebP supports both lossy and lossless compression as well as transparency, typically delivering smaller file sizes than PNG and JPEG for modern web pages.
