PNG is an image format introduced in 1996 as an open alternative to GIF. It's commonly used for logos, screenshots, web graphics.

Will converting PNG to JPG reduce quality?

Slightly. JPG uses lossy compression, so some fine detail is discarded. At normal viewing sizes, the difference is imperceptible.

How much smaller will the JPG file be?

Typically 60-80% smaller than the original PNG, depending on image content and quality settings.

What happens to transparency in my PNG file?

JPG doesn't support transparency. Transparent areas will become white by default.

Can I convert JPG back to PNG later?

Yes, but the JPG compression is permanent. Always keep the original PNG file if quality matters.
