Why Image Optimization Matters for Social Media

Social media platforms are highly visual, and optimized images are crucial for engagement. Large, unoptimized images load slowly, get auto-compressed by platforms (often with poor quality), and may even fail to upload. Properly optimized images ensure your content looks professional and loads quickly.
