How to convert PNG to JPG
- Choose or drop your PNG files. You can add many at once.
- The output is set to JPG. Adjust the quality, or the size under Advanced Options, if you like.
- Press Convert, then download the files one by one or all together as a ZIP.
Good to know
- Transparent areas are filled with white, or the background color you choose under the options.
- JPG is great for photos. For screenshots with text, PNG or WebP often stays sharper.
Your images stay on your device
Everything happens in your browser. Your images are never uploaded, so private photos and client work stay with you.
よくある質問
Why is my JPG bigger than the PNG?
Simple graphics with few colors compress better as PNG. JPG is best for photos.
Are my images uploaded?
No. They are processed in your browser and never sent anywhere.
