CodeBeautifyJPG to PNG Converter
Convert a JPG/JPEG image to lossless PNG, entirely client-side. Nothing is uploaded anywhere.
PNG uses lossless compression, so converting from JPG to PNG won't improve quality lost during the original JPG encoding, but it does avoid any further generational loss and adds support for transparency.
Frequently asked questions
How do I convert JPG to PNG online?
Click the upload area (or drag and drop a JPG onto it) and the PNG version is generated instantly using the browser's Canvas API — nothing leaves your device.
Will converting JPG to PNG remove compression artifacts?
No — any blockiness or artifacts already present in the JPG are baked into its pixels and will carry over into the PNG, which simply re-encodes those same pixels losslessly.
