The Ultimate Guide to Image Optimization for SEO
Images account for over 60% of the total file size of a typical webpage. Optimizing them is one of the most effective ways to speed up your site. Our **Free Image Optimizer** helps you compress and resize images without sacrificing quality, ensuring a faster user experience and better search engine rankings.
Why is Image Optimization Critical?
- Page Speed: Google uses page speed as a ranking factor. Smaller images load faster, improving your Core Web Vitals score.
- Bandwidth Savings: Optimized images consume less data, which is crucial for mobile users on limited data plans.
- Better UX: Users are less likely to bounce from a site that loads instantly.
Supported Formats
- WebP: The modern standard. It offers superior compression (25-35% smaller than JPEG) with high quality. Our tool can convert your images to WebP automatically.
- JPEG: Best for photographs and complex images with many colors.
- PNG: Ideal for images with transparent backgrounds or simple graphics/logos.
Best Practices
- Resize Before Uploading: Don't upload a 4000px wide image if it will only be displayed at 800px. Use our resize tool to scale it down first.
- Use Alt Text: Our tool suggests SEO-friendly alt text based on the filename. Always ensure your images are accessible to screen readers.
- Strip Metadata: Cameras add hidden data (EXIF) like GPS location and settings. This adds bloat. Our tool removes this by default to save space.
