Why convert JPG to WebP?
JPG (JPEG) uses lossy compression to make small files, which is why it is the default for photographs across the web. It does not support transparency. WebP is a modern Google format that compresses 25-35% smaller than JPG and PNG at similar quality, while supporting both transparency and animation.
- Shrink file size — WebP typically produces noticeably smaller files than JPG, which speeds up websites and saves bandwidth.
- WebP supports transparency, so you can later cut out backgrounds — something JPG cannot store.
