What is Image Compression?
Image compression is the process of reducing the file size of digital images while maintaining acceptable visual quality. This is achieved by removing redundant or unnecessary data from the image file.
Key Concept: Compression can be either lossless (no quality loss) or lossy (some quality loss for smaller file sizes). Most web images use lossy compression to achieve significant file size reductions.
Why Should You Compress Images?
- Faster Website Loading: Smaller images load quicker, improving user experience
- Better SEO: Google favors faster-loading websites
- Reduced Storage: Save space on your devices and servers
- Email Attachments: Smaller files are easier to send
- Social Media: Meet platform size requirements
- Mobile Optimization: Better performance on mobile devices
