JPG to PNG converter
Convert JPG images to PNG in your browser — no further loss, at the cost of a larger file. Free, no sign-up, nothing uploaded.
Part of image tools and design tools.
What happens to quality
PNG is lossless, so nothing further is lost — but nothing lost earlier comes back either. The compression artefacts already in the JPG are part of the pixels now, and PNG keeps them faithfully. Expect a larger file, often several times larger for a photograph; the reason to convert is a workflow that needs PNG, or editing the image without every save costing a little more detail. PNG is the right target for logos, icons, diagrams and screenshots of text, and for anything that will be edited and saved again.
What happens to transparency
JPG has no alpha channel, so there is no transparency to carry over and the PNG comes out fully opaque. PNG could hold transparency, but converting does not create it: a white background in the picture stays white pixels, not see-through ones.
Your JPG never leaves this page
Most online JPG to PNG converters upload the file to a server and send the result back. This one decodes and re-encodes it with the image APIs built into your browser, so the PNG you download was produced on your own machine — you can check by opening the network tab, or by going offline and converting anyway.
