How it works
Your JPG is rendered onto a canvas and exported using the lossless PNG encoder built into the browser. Re-compression starts from the decoded pixels, so there is no additional quality loss.
Frequently asked questions
Is JPG to PNG lossless?
From the decoded pixels, yes. Note that the original JPG itself already lost detail when it was first encoded.
Why is the PNG larger than the JPG?
That is normal - PNG does not apply lossy compression, so photographic detail takes more space.
Can I convert PNG to JPG here too?
Yes, with the PNG to JPG tool, which lets you control the JPEG quality.
