When to use PNG to JPG
Choose JPG when a form or older app rejects PNG. JPG usually makes photos smaller, but it re-encodes image detail and has no transparency; transparent PNG areas become white.
Quality and file size
Text, logos, and sharp edges can show compression artifacts. Keep the PNG when you need transparent pixels or lossless decoded image data.
Frequently asked questions
What happens to transparent pixels?
JPG has no alpha channel, so transparent areas are filled with white.
Will the JPG be smaller?
Often for photos, but not guaranteed; size depends on image content and compression.
Does JPG preserve all PNG detail?
No. JPG is lossy. Keep the PNG for sharp graphics or lossless pixels.
Are my images uploaded?
No. Conversion runs locally in this browser tab.
