Frequently Asked Questions

Why is PNG file so much bigger than JPG?
PNG uses lossless compression - it preserves every pixel exactly. JPG uses lossy compression optimized for photos, discarding data your eye can't detect easily.
What happens to transparency when converting to JPG?
JPG doesn't support transparency. Transparent areas become a solid color (usually white). Choose your background color during conversion.
Will I lose quality converting PNG to JPG?
Some quality loss occurs due to JPG compression. Use 90%+ quality for photos. Note: Already-JPG images shouldn't be converted repeatedly.
Can I convert JPG back to PNG?
Technically yes, but you won't recover lost quality. The resulting PNG will just be larger without better quality.
