Frequently Asked Questions
QWill converting JPG to PNG improve quality?
No — any quality lost during the original JPG compression cannot be recovered. However, the PNG output is lossless, so no further quality is lost from this point on. It is useful when you need to re-edit and re-save multiple times.
QWhy is the PNG larger than the JPG?
PNG is a lossless format and does not discard pixel data like JPG does, resulting in a larger file size. This is the trade-off for perfect quality.
QIs my file uploaded anywhere?
No — everything runs locally in your browser. Your image never leaves your device.
About This Tool
The JPG is loaded into an Image element, drawn onto a Canvas, and exported as PNG using canvas.toDataURL("image/png"). Since PNG is lossless, the output is a pixel-perfect representation of what the browser decoded from the JPG.
