Best Practices for Instagram Images

•Always use 1080px width — Instagram compresses smaller images, making them blurry.
•Use JPG for photos — Smaller file size, faster upload.
•Use PNG for graphics/text — Sharper edges, no compression artifacts.
•Keep file size under 8MB — Instagram's upload limit.
•Compress after resizing — Reduces file size without visible quality loss.

After Resizing: Optimize Your Image
