Frequently Asked Questions

Can I convert a transparent PNG to JPEG?

Yes. Because JPEG does not support transparency, transparent pixels are placed on a white background.

Does conversion reduce quality?

JPEG and WebP can use lossy compression. PNG output is lossless, while the quality slider controls supported lossy formats.
