Will converting PNG to JPG reduce file size?
Usually yes, especially for photos and screenshots. Adjust the quality slider to balance size and sharpness.
What happens to transparent backgrounds?
JPG cannot store transparency, so transparent areas are flattened onto a background color during conversion.
Are my images uploaded to a server?
No. The converter runs locally in your browser and your images stay on your device.
