JPEG's lossy DCT compression is everywhere — cameras, phones, the entire web — but some workflows demand PNG: certain upload forms, print pipelines, and editing tools that reject lossy formats. Converting here re-wraps the decoded pixels in PNG's lossless DEFLATE packaging. Be aware this can't add detail back — JPEG artifacts that exist stay frozen in place — but it does stop further loss and satisfies tools that only accept .png, all without the file leaving your browser.

How to convert JPG to PNG
Drop the .jpg (or .jpeg) file onto the converter above.
The file's JPEG start-of-image marker is checked before anything else happens.
Click Convert — the photo is decoded and re-encoded as PNG locally.
There's no quality slider: PNG is lossless, so pixels are preserved exactly as decoded.
Download the .png, ready for whatever tool demanded the format.
Frequently asked questions
Does converting JPG to PNG improve quality?
No — the JPEG's existing compression artifacts are baked into the pixels and PNG faithfully preserves them. What you gain is format compatibility and immunity to further loss: re-saving a JPEG repeatedly degrades it, while the PNG stays fixed.
Why is the PNG file bigger than the JPG?
JPEG achieves its small size by discarding information; PNG keeps every pixel and compresses losslessly, which is far less efficient on photographic content. Expect the PNG to be several times larger.
Will the PNG have a transparent background?
No. JPEG never had transparency information, so there's nothing to recover — the PNG is fully opaque. Making a cutout requires an editing tool, not a format conversion.
Is this private?
Completely. Decoding and encoding happen inside your browser tab with no network activity — verifiable in your browser's developer tools.
