How this tool works
JPG pixels are decoded and encoded as PNG entirely inside a disposable browser worker.
- Choose one or more JPG images.
- Process the queue and download the PNG files.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.
