What is the purpose of making an image transparent in graphic design?

Making an image transparent primarily serves the purpose of allowing background visibility. This technique is frequently employed in graphic design to create visually appealing compositions where elements can be layered without obscuring one another. For example, a designer might want to place a logo on a textured background while maintaining the logo's visibility; using transparency achieves this by letting the underlying background show through the transparent parts of the logo.

This approach is especially important in scenarios like web design, where logos or images need to blend harmoniously with varied backgrounds without requiring a solid color that might clash with other design elements. Transparency contributes to a more cohesive and polished design while enabling creative expression and flexibility in layout decisions.
