Convert JPG to PNG

Turn a JPG into a lossless PNG that edits cleanly and supports transparency — free, in your browser, nothing uploaded.

One or many — nothing is uploaded.

On your device.Your photo is decoded by code running in this browser tab. It is never uploaded — you can watch the Network tab in your browser’s developer tools stay empty while it converts.

Converting a JPG to PNG gives you a lossless container: from this point on the pixels are stored exactly, with no further JPEG artifacts added each time you save. That makes PNG the better working format when you are about to edit an image repeatedly, or when a tool or upload form specifically asks for a PNG.

It is worth being honest about what this does not do: a JPG has already thrown away detail when it was first compressed, and turning it into a PNG cannot bring that detail back. What you get is a faithful, lossless copy of the JPG as it is now — useful, but not a magic quality upgrade. The PNG will also be larger, since lossless storage of a photo takes more bytes.

PNG also supports transparency, so this is the format to convert to if you plan to erase a background afterward. Drop a batch and grab them as one .zip. The conversion happens in this browser tab and nothing is uploaded.

Frequently asked questions

Does converting JPG to PNG improve the quality?
No — the JPG already discarded detail when it was compressed, and PNG can’t recover it. You get a clean, lossless copy of the JPG as it is now, ideal for editing, but not a quality upgrade.
Why is my PNG larger than the original JPG?
PNG is lossless, so it stores a photo with much more data than JPG’s lossy compression — usually several times larger. That size buys exact pixels and transparency support.
Can I add transparency after converting to PNG?
The PNG gains an alpha channel, so a later edit can make areas transparent — but the conversion itself doesn’t remove a background; it just produces a PNG that can hold transparency.
