- Xylakant 6y agoCompression in the context of (jpeg) images often implies lossy compression. You can apply that multiple times ans still gain size benefits. Other ways are stripping metadata and reducing color palettes. Images on websites are often horribly unoptimized, so if you’re willing to compromise a little on quality you can have substantial gains in bandwidth requirements.
