Make the most of image converter
JPG is useful for photographs; PNG works well for sharp graphics and transparency. When JPG is selected, adjust compression quality and watch the estimated output size and percentage change update before downloading. Transparent areas become white when converted to JPG. PNG output is lossless, so the quality slider is disabled and its file size may be larger.
The tool decodes and re-encodes the image in your browser, so embedded metadata is not copied. Animated inputs are exported as a single still image.
