Frequently Asked Questions
What happens to transparent pixels when converting PNG to JPG?
Because JPEG does not support transparency, transparent background areas are automatically filled with clean solid white (or a background color of your choice).
Why should I convert PNG to JPG?
PNG files are often 3x to 5x larger than JPGs. Converting screenshots and non-transparent photos to JPG significantly saves storage space and speeds up website loading.
