About JPG to PNG
JPG and PNG are both standard image formats. This converter uses your browser's built-in image decoder and the Canvas API to re-encode each image as PNG. Nothing is sent over the network.
Frequently asked questions
Is this JPG to PNG converter free?
Yes, it is free with no sign-up, no watermark and no file limits beyond what your device can handle.
Are my files uploaded?
No. Conversion runs entirely in your browser. Your files never leave your device — you can even go offline after the page loads.
Will the PNG be bigger than the JPG?
Usually yes. PNG is lossless, so files are often larger than the lossy JPG original, but no further quality is lost.
Can I convert many files at once?
Yes. Select or drop as many files as you like; each one is converted in turn and gets its own download button.
