Will the PNG look different?

No. PNG is lossless, so the result is pixel-for-pixel identical to your JPG.

Will the file get bigger?

Often, yes. PNG stores photo data without lossy compression, so photos can grow. That's the cost of lossless quality.

JPG to PNG

Wraps your JPG in lossless PNG. Nothing degrades, though the file usually grows.

What this does

This tool re-encodes your JPG images as lossless PNG. The pixels are drawn onto a PNG canvas, so nothing is compressed or degraded. Because PNG stores photo data without lossy compression, the output file is typically larger than the original JPG.

How it works

1Drop your JPG images.
2Each one gets redrawn onto a PNG canvas.
3Download them one by one, or grab the whole batch as a zip.
