1. Performance & Speed
-
Faster upload time on both web and mobile apps, even on slow networks (3G/4G).
-
Improves website & app responsiveness, reducing waiting time for users.
-
Lower Time-To-First-Byte (TTFB) and better overall Core Web Vitals score.
2. Storage & Cost Optimization
-
Saves cloud/server storage costs (especially on AWS S3, Firebase, or other CDNs).
-
Reduces database load and bandwidth usage.
-
Helps keep backups smaller and faster.
3. Mobile User Convenience
-
Many users on eCommerce apps upload images (profile pictures, product images, ID proofs, etc.) via mobile networks. Smaller files = smoother uploads without failures.
-
Prevents app crashes or timeouts caused by large uploads.
4. Better User Experience
-
Users don’t have to wait long or retry uploads.
-
Validation alerts before upload prevent frustration (instead of letting users upload 10MB and then failing).
-
Increases trust in platform usability.
5. Improved SEO & Site Ranking
-
Smaller image files (like product images, banners) lead to faster page loads.
-
Faster page loads = better SEO ranking on Google (Core Web Vitals).
-
Lower bounce rates, higher conversion rates.
6. Security & Risk Reduction
-
Large files can sometimes be exploited for malware injection or DoS (Denial of Service) attacks.
-
Setting a size cap (<1MB) adds a layer of protection.
7. Compliance & Standards
-
Many app stores (Google Play, App Store) recommend optimized assets for better app performance.
-
Meeting these guidelines ensures smoother approval and long-term scalability.
8. Cross-Device Compatibility
-
Smaller files render consistently across devices with different RAM and CPU capacity.
-
Ensures images display quickly even on low-end Android devices or older browsers.
