Frequently Asked Questions
Why do my Instagram photos lose quality?
If you upload an image larger than 1080px in width, Instagram automatically compresses it, which can cause artifacting. Resizing it exactly to 1080px beforehand often preserves better quality.
Is a portrait post better than a square post?
Portrait posts (1080x1350) take up more vertical screen real estate on a user's phone, making them more engaging and prominent in the feed than traditional square posts.
