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.

Will the aspect ratio be preserved?

Yes in "fit" mode. "exact" stretches to the exact size without cropping.

Does upscaling blur the image?

Upscaling reduces clarity. Stay at or below the original size when possible.
