Perkforge
How it works
Choose or drop a JPG file, check the preview and convert it locally. Download the new PNG when it is ready. Nothing is uploaded and no account is required.
Useful to know
PNG preserves the pixels present in the JPG but cannot restore detail already lost through JPEG compression. The PNG file may be larger.
Private by design
