Why Instagram lowers your image quality

Instagram resizes anything wider than 1080 pixels and re-compresses anything outside a supported aspect ratio. A 4000 pixel export is not higher quality on Instagram, it is just a bigger file for the encoder to crush.

  • Export at exactly 1080 pixels wide.
  • Use one of the supported ratios so no automatic crop is applied.
  • Upload over Wi-Fi. Instagram degrades uploads harder on a weak connection.
  • Turn on high quality uploads in Settings, then Data usage and media quality.
  • Use PNG for graphics with flat colour and text, JPEG for photographs.

The carousel trap

A carousel applies the aspect ratio of the first slide to every slide after it. If slide one is square and slide four is portrait, slide four gets cropped. Decide the ratio before you design the set.

Once the post is sized correctly, the next question is what it asks people to do. How to post on Instagram covers captions and the comment-a-keyword ask that turns a post into leads.
