What is webp?
An image format supporting lossy and lossless compression plus transparency; the quality and file size depend on the selected mode and source image.
WebP supports both lossless compression (like PNG) and lossy compression (like JPEG) in the same format, plus an alpha channel, which is why it typically beats both older formats on file size for a comparable result. Browser support is now essentially universal.
The main reason to still use PNG or JPEG instead is compatibility with older tools and platforms that don't accept WebP uploads directly - check the target before assuming WebP works everywhere.
