❓ Frequently asked questions
What happens to transparency when converting PNG to JPG?
JPG does not support transparency, so this tool fills transparent pixels with white before exporting the image.
Are my images uploaded to a server?
No. Decoding, resizing, conversion, and ZIP creation all happen locally in your browser. Your original images never leave your device.
