How to Convert PNG to JPG (Free, No Quality Loss You'll Notice)

PNG files are often huge. Converting to JPG can cut the size by 80% or more with no visible loss — here's when and how to do it.
PNG to JPG is the conversion to reach for when a PNG is just too big. Screenshots, exported graphics and phone captures often land as heavy PNGs — and turning them into JPG can cut the file size by 80% or more with no loss you'll ever notice at normal viewing sizes. Here's when converting PNG to JPG makes sense, when it doesn't, and how to do it free.
Why convert PNG to JPG
Smaller files. PNG is lossless, so photos and detailed screenshots balloon in size. JPG uses smart compression built for exactly this content — the same image can be a fraction of the size.
Faster uploads and pages. Lighter files load quicker and clear upload limits.
Universal support. Every device, app and form accepts JPG.
When to keep the PNG instead
Keep PNG when the image has transparency (JPG can't store it — you'd get a solid background) or when it's a logo, icon or line graphic with sharp edges and flat colour, where PNG stays crisp and small. For screenshots of text you'll zoom into, PNG also keeps letters sharper. For everything else — especially photos — JPG wins on size.

What happens to transparency
A PNG with a transparent background will get a solid background when saved as JPG (usually white), because JPG has no transparency channel. If you need to keep transparency, stay with PNG. If the transparency doesn't matter — the image sits on a white page anyway — converting to JPG is a free, easy win on file size.
