Why Image Compression Matters for SEO

Large, unoptimized images are the number one cause of slow website loading times. Search engines like Google actively penalize slow websites by dropping them down the search rankings. By utilizing our online image compressor, you can:

• Dial in the exact quality level you need using our interactive slider.
• Use the Visual Comparison Slider to compare the original image and the compressed output side-by-side to guarantee no visual artifacts.
• Automatically crop and resize images to standard responsive web dimensions (e.g., 800px, 1200px, 1920px).

WebP vs AVIF: Next-Generation Formats

If you are still serving standard PNGs and JPGs on your website, you are wasting bandwidth. WebP (developed by Google) and AVIF (based on the AV1 video codec) are next-generation image formats that provide vastly superior compression. WebP is widely supported across all modern browsers and offers excellent quality at tiny file sizes. AVIF offers even better compression ratios and is quickly becoming the new industry standard. Use our bulk batch converter to migrate your entire media library to AVIF today and drastically improve your website's performance!
