Best Practices for Image Compression
1. Website Image Optimization
Reducing file size is critical for faster website load times and improved SEO rankings. Use WebP format for modern browsers, keep quality between 70–85% for photos, and always remove unnecessary metadata. For e-commerce product images, maintain 85–95% quality to preserve detail.
2. Social Media Image Compression
Every platform has different requirements:
- Facebook / Instagram: JPG at 80–90% quality, 1080px width max.
- Twitter: JPG at 70–80% quality, under 5MB.
- Pinterest: JPG at 85% quality, at least 1000px wide.
- LinkedIn: JPG at 80% quality, 1104×736px recommended.
3. Email Attachments
Reduce image size for email to avoid hitting attachment limits. Target a total of 1–2MB for all images combined. Use JPG at 70–75% quality, and convert PNG to JPG if transparency is not required.
Understanding Image Compression: Lossy vs. Lossless
- Lossy Compression: Reduces file size by removing some image data. Used in JPG and WebP.
- Lossless Compression: Retains all image data. Used in PNG and some WebP formats.
- Chroma Subsampling: Compresses color data while keeping brightness sharp – barely noticeable to the human eye.
- Metadata Removal: Strips EXIF and GPS data to further reduce file size.
Advanced Image Optimization Techniques
- Progressive JPGs: Load a low-quality version first, then sharpen details for better UX.
- Adaptive Compression: Apply higher quality to detailed areas and lower quality to smooth areas.
- Resize Before Compression: Always scale your image to display size before compressing.
- WebP Format Benefits: Supports both lossy and lossless compression in one format.
