Understanding Image Compression
Image compression is the process of reducing the file size of an image to save space and bandwidth. There are two primary types of image compression: lossy and lossless. Lossy compression sacrifices some quality for a smaller file size, while lossless compression retains all original data.
Why Compress Images?
- Faster Load Times: Compressed images load quicker, improving user experience.
- Reduced Bandwidth Usage: Smaller image files consume less bandwidth, which can save costs.
- Enhanced SEO: Search engines favor faster-loading websites, potentially improving your rankings.
- Storage Efficiency: Compressed files take up less space, allowing for more storage of images.
