How do I avoid quality loss from Instagram's re-compression?

Instagram re-encodes every upload. Export at 80–85% quality and ≥1080px wide so the server-side re-compression has less room to degrade the image.

What are the recommended sizes?

1080×1080 for square feed posts, 1080×1920 (9:16) for stories and reels.

40–70% on average. Depends on the image and your quality setting.

The default 78% is a practical balance; raise it for professional use.
