Make Google love
your images.

Yes, significantly. WebP images are typically 25-35% smaller than equivalent JPEGs and 26% smaller than PNGs at the same visual quality. Google's PageSpeed Insights and Core Web Vitals directly measure image optimization, and "Serve images in next-gen formats" (WebP/AVIF) is one of the most impactful recommendations. Sites that switch to WebP typically see LCP (Largest Contentful Paint) improvements of 0.5-2 seconds.

WebP is now supported by all modern browsers including Chrome, Firefox, Safari (since 2020), Edge, and Opera — covering over 97% of global web users as of 2025. The only exceptions are very old versions of Safari (pre-2020) and Internet Explorer, which represent less than 1% of traffic. For maximum compatibility, you can use the HTML picture element to serve WebP to supported browsers and JPEG as fallback.

For most web images, a quality setting of 75-85 provides an excellent balance between file size and visual quality. Product photos and hero images that need to look sharp: use 85. Blog thumbnails, background images, icons: use 70-75. The default setting of 80 in ImageCrush works well for 90% of use cases and typically reduces file size by 60-75% compared to the original.

The free tier allows 5 images per day with individual file uploads. Pro users ($2.99/month) get unlimited compressions, bulk ZIP uploads, and API access. There is no file size limit for individual images — the tool handles files up to 25MB. For bulk optimization of an entire website's image library, the Pro plan pays for itself in a single session.
