Why compress images? (Benefits)
Image compression is not all about saving space; it improves performance, accessibility, and security in various ways. Here is why:
Website Loads Faster
Heavy images slow down page speed, which affects:
- User experience
- Conversion rates
- Engagement
- Search engine rankings
Compressed images help your website load faster, improve Core Web Vitals, and boost SEO.
Saves storage and bandwidth.
Compressed images decrease the file size by up to 80%, helping you:
- Store more images without upgrading storage
- Upload large batches instantly
- Reduce mobile data usage
This is especially helpful for students, photographers, and social media users.
Improves SEO and Online Visibility
Search engines give priority to fast-loading pages. You can achieve this by:
- Improve ranking potential
- Lower bounce rate

- Improve user retention
Better performance means better visibility.
