JPG to PNG Converter
Turn a JPG into a lossless PNG — ideal for editing and clean re-saving. Free, private, straight in your browser.
Why convert JPG to PNG?
A PNG is lossless, so once you’ve converted a JPG you can edit and re-save it without piling on more compression artefacts each time. PNG is also the right format if you’re about to add transparency. Lumisphere converts in your browser — drop a JPG (or many) and download PNGs, with no upload, sign-up or watermark. Note that converting can’t recover detail the JPG already threw away.

Good to know
How do I convert a JPG to PNG?
Drop your JPG in, choose PNG, and download — it becomes lossless and ready for clean editing, with no upload or sign-up.
Does converting JPG to PNG improve quality?
It won’t add detail back — a JPG has already discarded some. But PNG is lossless, so from here on you can edit and re-save without further quality loss.
Will the PNG be bigger than the JPG?
Usually yes — PNG keeps every pixel exactly, so photographic images get larger. The upside is no compression artefacts and clean editing.
Can I make the white background transparent?
Not with the converter alone — use the background remover to erase a solid background, then you’ll have a transparent PNG.
Is it free and private?
Yes — no sign-up, no watermark, no limit, and the JPG is converted on your device, never uploaded.
