Best Practices for Image Compression
For Websites
Use 70-80% quality and max width of 1920px. This keeps images sharp while loading fast.
For Social Media
Instagram and Facebook compress images anyway. Use 75-85% quality for best results.
For WhatsApp / Messaging
Lower quality (60-70%) is usually fine since apps re-compress images.
For Printing
Keep quality at 90%+ and avoid resizing. High resolution is more important.
