Free JPG to PNG Converter Online

JPG to PNG Converter transforms JPEG images into PNG format. JPEG uses lossy compression that discards subtle image data each time it's saved — opening and re-saving a JPEG degrades quality further. Converting to PNG first, then saving as PNG (which is lossless), prevents any additional quality loss. PNG also supports transparency, making it better for logos, icons, and any image that needs to sit on colored backgrounds.

The JPEG is decoded and drawn onto a canvas, then exported as a PNG blob using toBlob(). PNG uses lossless DEFLATE compression, so the quality of the source image is preserved. Note that converting a JPEG to PNG won't recover quality lost during JPEG compression — it only prevents future loss.
