Questions

Frequently asked questions

No. PNG is lossless for future saves, but it cannot restore detail that was already removed when the image became a JPG.

PNG stores pixels differently and is often larger for photo-like images, especially when the source JPG was already compressed.

No. A normal JPG has no transparent pixels, so the converted PNG keeps the same visible image on an opaque canvas.
