How to Properly Optimize Images for the Web
Image optimization is essential for improving website loading speed and user experience. Properly optimized images reduce page weight, save bandwidth, and improve SEO performance.
Here are a few practical tips:
- Use modern formats like WebP, which offer high quality at smaller file sizes compared to JPG or PNG.
- Upload images in the exact size needed for display to avoid unnecessary weight.
- Compress images without quality loss to reduce file size while maintaining visual clarity.
- Remove unnecessary metadata — FastConvert automatically handles this during compression.
- Balance quality and file size to ensure your images look great and load fast on all devices.
By following these guidelines and using FastConvert, you ensure your website loads faster, ranks higher in search engines, and delivers a better experience for every visitor.
