<h3>Why WebP?</h3>
<p>WebP is a modern image format developed by Google that provides both lossy and lossless compression for images on the web. Here are some benefits of using WebP:</p>
<ul>
<li><strong>Smaller File Size</strong>: WebP images can be up to 30% smaller than JPEGs and PNGs with no noticeable loss in quality, resulting in faster page load times.</li>
<li><strong>Transparency and Animation</strong>: WebP supports transparent backgrounds like PNG and animated images like GIF, making it a versatile choice.</li>
<li><strong>Improved Compression</strong>: WebP offers better compression algorithms compared to traditional formats, allowing for high-quality images with lower storage requirements.</li>
</ul>
<h3>Why AVIF?</h3>
<p>AVIF (AV1 Image File Format) is a cutting-edge image format derived from the AV1 video codec, offering even better compression than WebP. Here’s why AVIF is beneficial:</p>
<ul>
<li><strong>High Compression Efficiency</strong>: AVIF can reduce image sizes by up to 50% compared to JPEG, while maintaining similar or even higher visual quality.</li>
<li><strong>HDR Support</strong>: AVIF supports High Dynamic Range (HDR), allowing for more vibrant and detailed images, especially on modern displays.</li>
<li><strong>Advanced Features</strong>: It includes support for transparency, animation, and a wider color gamut, making it suitable for various types of web content.</li>
</ul>
