Does conversion improve quality?

No. JPEG artifacts stay. You only change the container to PNG.

Is the image resized?

Only if a side is larger than about 2048px, to keep memory safe. Smaller images keep their native size.

Next step for a favicon.ico?

Send the PNG through the PNG to ICO converter, or use the full generator.

JPG to PNG converter

Re-encode a JPEG as PNG without uploading it. Useful when your asset pipeline or favicon pack expects PNG, or before packing an ICO. Dimensions stay the same unless the long edge exceeds a soft memory cap.

Lossless container, same pixels

PNG stores the decoded JPEG pixels without further JPEG compression. File size usually grows; quality does not improve beyond the original JPEG.

No alpha from JPEG

The PNG will be opaque. If you need a transparent favicon, start from PNG, WebP, or SVG, or design one in the generator.
