Basic Knowledge of Image Compression
What is Image Compression?
Image compression is the process of reducing the size of image files by decreasing data volume while preserving visual quality as much as possible. Compressed images load faster, take up less space, and are especially suitable for web transmission and storage.
Lossy Compression
Reduces file size by removing some image data, cannot fully restore original image quality, suitable for JPEG format.
Lossless Compression
Reduces file size without losing image quality, suitable for PNG, WebP and other formats that support lossless compression.
Common Image Format Characteristics
JPEG/JPG
- • Supports lossy compression, high compression ratio
- • Suitable for photos and complex images
- • Does not support transparency
- • Relatively small file size
PNG
- • Supports lossless compression and transparency
- • Suitable for icons, text and simple graphics
- • Usually larger file size
- • Supports 24-bit and 32-bit colors
WebP
- • Modern image format developed by Google
- • Supports both lossy and lossless compression
- • 25-34% smaller file size than JPEG
- • Supports transparency and animation
Application Scenarios for Image Compression
Website Optimization
Reducing image size can significantly improve website loading speed, enhancing user experience and search engine rankings.
Mobile Applications
Optimized images reduce data usage on mobile devices and improve application performance.
Cloud Storage
Compressing images saves storage space and reduces cloud storage costs.
Social Media
Compressed images are easier to share and upload on social media platforms.
Image Compression Tips
For photo images, JPEG format typically achieves good compression at 80-90% quality setting
For images requiring transparent backgrounds, choose PNG or WebP format
Resizing images is usually more effective at reducing file size than lowering quality
For most web usage scenarios, WebP format offers the best balance of compression efficiency and quality
Back up original images before compression to restore high-quality versions if needed
For large numbers of images, using batch compression can save time and improve efficiency
