Good to Know
Converting to PNG does not restore detail that JPG compression already removed, and it does not make the background transparent by itself. What it does is stop further quality loss: a PNG can be edited and re-saved many times without degrading.
Expect the PNG to be larger than the original JPG, often 2–5× for photos. That is normal for a lossless format. If you need a transparent background, run the result through our background remover.
Frequently Asked Questions
Why is my PNG file bigger than the JPG?
PNG is lossless and stores every pixel exactly, while JPG throws away detail to save space. For photos, a PNG is usually several times larger. This is expected and the image will look the same.
Does converting JPG to PNG improve quality?
No. Detail lost to JPG compression cannot be recovered. Converting prevents further loss when you edit and save the image again.
Will the PNG have a transparent background?
Not automatically. JPG has no transparency, so the PNG keeps the original background. Use the Remove Background tool to make it transparent.
Can I convert JPEG files too?
Yes. JPG and JPEG are the same format with different file extensions, and both are supported.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device, which is why it also works with private photos and confidential documents.
