Drop JPGs here to get PNG copies, for when an app or form insists on PNG. Converting does not improve quality: the PNG holds exactly the JPG's pixels.

## How to use it

1. Drop .jpg or .jpeg files.
2. They convert immediately.
3. Download the PNGs or a zip.

## Details

- **Input:** JPG, JPEG
- **Output:** PNG, same pixels, no transparency added
- **Limits:** No file count limit. Very large images (above ~16,000 px on a side, or ~250 megapixels on phones) can exceed the browser's canvas limit.

## Questions

### Are my files uploaded?

No. The page loads its code once, then reads and processes your files inside the browser tab. Nothing is sent to a server; you can confirm it in your browser's network panel while a file converts.

### Will the background become transparent?

No. A JPG has no transparency, so the PNG has the same solid background. Removing a background is a separate job.

### Why is the PNG several times bigger?

PNG is lossless and stores every pixel, while JPG discards detail you rarely notice. The bigger file has no extra detail; it is only less compressed.
