Free WebP Compressor: Maximize Website Speed and Quality

WebP is the fastest-growing image format on the web. Developed by Google, WebP files are significantly smaller than equivalent JPEGs and PNGs, making them essential for a fast, modern website.
ImgSmaller.com’s WebP Compressor is specifically engineered to take advantage of this format's superior compression technology. Whether you need to maintain perfect quality or achieve the smallest possible file size, our tool gives you the power to optimize WebP images instantly.
Why WebP is an SEO Game-Changer
Google has consistently pushed for faster web performance, and serving images in WebP format is one of the easiest ways to get a major site speed boost.
- 
Smaller Files, Faster Load: On average, WebP Lossy images are 25-34% smaller than JPEGs, and WebP Lossless files are 26% smaller than PNGs. This directly translates to better Core Web Vitals scores and higher Google rankings.
 - 
Modern Format Authority: By supporting and promoting WebP, your website positions itself as a forward-thinking utility, attracting users who are serious about performance.

Common WebP Optimization Mistakes to Avoid
To ensure your images rank and perform well, keep these points in mind:

Avoid Over-Compression: While a smaller file is good, dropping the quality too low (e.g., below 60%) can result in noticeable visual artifacts. Use our preview to check before downloading.
 - 
Always Provide Fallbacks: Although WebP is widely supported, ensure your CMS provides a JPEG or PNG fallback for older browsers. Hint: Use ImgSmaller to compress the fallback image, too!
