FAQ

Does converting JPG to PNG create a transparent background?

No. JPG has no alpha channel, so converting to PNG only changes the container — the original white or coloured background is kept.

Why is WEBP noticeably smaller?

WEBP uses a more efficient compression algorithm and is typically 25–35% smaller than JPG at comparable visual quality, which makes it ideal for websites.

Does conversion reduce quality?

Converting to PNG is lossless. Converting to JPG or WEBP re-encodes the image, but quality loss is minimal with the default settings.
