About This Tool
Save a PNG as a widely supported JPG for uploads that require JPEG, or try reducing the size of a photographic PNG. For text screenshots and icons, compare fine details before choosing the result.
How to Use
- Select or drag in a PNG image. The checkerboard marks transparent areas in the original.
- Choose a background color, which defaults to white. Adjust JPEG quality as needed; the default is 90%.
- Click “Convert to JPG” to see the filled background and the change in file size.
- Once you are happy with the result, click “Download JPG.”
Supported Formats
- Input: PNG (.png).
- Output: JPEG (.jpg, image/jpeg).
Conversion Details
- JPG does not support transparency. Transparent and partially transparent pixels are blended with your chosen background color, with no transparency channel retained.
- Quality ranges from 10% to 100% and defaults to 90%. Lower quality usually makes the file smaller but may introduce blur or compression artifacts. Even 100% is not lossless.
- Image width and height stay the same. Whether the file gets smaller depends on the image content and quality setting.
- Converted images generally do not retain the original EXIF, GPS, or other metadata. Keep the original file if you may need its camera information later.
Maximum file size: 100 MiB. Files over 50 MiB trigger a high memory usage notice. Images are limited to 40 million pixels and 16,384 pixels per side. Resize larger images in another image tool first.

FAQ
What happens to a PNG’s transparent background?
It is filled with your chosen background color, which defaults to white. Partially transparent edges are also blended with that color.
What does JPG quality mean?
It balances image detail against file size. Start at 90% and adjust based on the preview. A setting of 100% does not guarantee lossless output.
Why might a PNG become smaller as a JPG?
JPG uses lossy compression and often saves space for photos. The result depends on the image content and quality setting.
Are my images uploaded to a server?
No. Selection, preview, conversion, and download all happen in your browser. Your images are never uploaded to a server.
