Convert JPG photos to PNG without uploading them. Add a transparent background later or just keep lossless quality. Free.
How to use JPG to PNG Converter
- Open the toolNo signup and nothing to install; it works as soon as the page loads.
- Read the resultChange any input and the result is recalculated immediately.
Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
JPG to PNG Converter only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
Frequently Asked Questions
- Does it add transparency?
- No. A JPG has no transparency, so the PNG will have a white (opaque) background.
- Is the conversion lossless?
- PNG is lossless, but the source JPG is already compressed, so quality cannot improve.
