What is a JPG to PNG converter?
A JPG to PNG converter changes JPEG image files into PNG files that use lossless PNG encoding. The conversion runs locally in your browser. It cannot restore detail already lost in JPG compression, preserve every camera metadata field, or remove an image background.

Frequently Asked Questions
Quick answers to common questions about using this tool.
Does converting JPG to PNG improve image quality? +
No. PNG uses lossless encoding for the converted pixels, but it cannot restore detail already lost when the JPG was created.
Are my JPG images uploaded? +
No. Image conversion happens in your browser. The image files are not sent to the PotatoTools server for conversion.
Does JPG to PNG remove the background? +
No. Changing JPG to PNG changes the file format; it does not remove or make the background transparent.
Why can a PNG file be larger than the JPG? +
PNG preserves the decoded pixels without JPG-style lossy compression, so the resulting file can be larger than the original JPG.
