How to convert JPG to PNG
- Choose or drop your JPG files. You can add many at once.
- The output is set to PNG. Change 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
- PNG is lossless, so nothing is lost in the conversion, but files are usually larger.
- Converting doesn't make the background transparent: the picture stays exactly the same.
- Photos are turned the right way up using their stored rotation.

常见问题
Does converting to PNG improve quality?
No. It keeps the current quality exactly, but can't restore detail lost in the JPG.
Are my images uploaded?
No. They are processed in your browser and never sent anywhere.
