Trascina le tue immagini.

Compress and optimize images for the web.

Images are the single biggest performance bottleneck on most websites — accounting for 50-80% of total page weight. Optimizing them is the most impactful thing you can do for page speed, Core Web Vitals, and SEO.

A 5 MB hero image becomes 200-500 KB with no visible quality difference after compression to WebP at quality 80. Page speed improves by seconds, and Google rewards the improvement with better rankings.

Key features

• WebP and AVIF conversion for 25-50% smaller files
• Quality 75-85 optimized for web delivery
• Resize to display dimensions before compression
• EXIF metadata stripping for smaller files
• Batch processing for entire site image libraries

How to web image optimizer — step by step

1. Drop your images: Drag website images onto the upload area. Supports JPEG, PNG, WebP, AVIF, and GIF.
2. Set web-optimized quality: Choose quality 75-85 for the best balance. Enable target-size mode for CMS-specific limits.
3. Convert to WebP or AVIF: Set output to WebP (97%+ browser support) or AVIF. This alone reduces file size by 25-50% compared to JPEG.
4. Download and deploy: Save individual files or all as a ZIP. Replace your site's images and measure the PageSpeed improvement.
