🚀 Tips to Optimize Images Further
- Compress images after exporting from editing software (use quality 70–85% for JPEG).
- Resize images to exact display size — avoid massive dimensions.
- Use tools like TinyPNG, Squoosh, or your compressor for further reduction.
- Implement lazy loading on your site to improve load times.
✅ Final Thoughts
Image format choice matters for both performance and experience. JPEG delivers small files for photos, PNG ensures quality for graphics, and WebP offers the best of both worlds — smaller size and high quality. Choose the right format, compress smartly, and watch your website speed and user satisfaction grow.
