Features
Private by design
Conversion happens on your device with your browser's own image engine.
Batch ready
Convert many files at once and download them together as a ZIP.
Sensible defaults
Converting doesn't restore detail already lost to JPG compression — it just stops any further loss.
Good to know
Transparency can't be created from a JPG, but the PNG can be edited with transparent areas later.
Supported formats
Input: JPG (and other common image formats). Output: PNG.
Frequently asked questions
How do I convert JPG to PNG?
Drop your JPG files onto the converter, click Convert, and download the PNG results. It all runs in your browser.
Is converting JPG to PNG lossless?
PNG itself is lossless, so no further quality is lost — but detail already lost in the source can't be recovered.
Can I convert many files at once?
Yes. Add as many as your device's memory allows; they are processed in parallel by background workers and can be downloaded as a ZIP.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
