Great to list the logos of companies you are proud doing business with — partners, clients or customers. You can list the logos in rows and columns or a carousel.
Page speed impact:
We recommend adding SVG files, as they will have a low impact on page speed, compared with JPG or PNG files.
If you are adding PNG or JPG files, please make sure they are not too large, and we strongly recommend optimizing them first with TinyPNG, without losing in quality.
It may have a medium or even high impact if placed above the fold and your images are not optimized.
