Best Size and Crop Notes

Instagram feed posts perform best when the crop is intentional. The portrait 1080 x 1350 format gives more vertical screen space than a square image, which is useful for photographers, shops, and creators who want a cleaner feed preview.

Recommended workflow

  1. Upload your image Use a JPG, PNG, or WebP file up to 5MB.
  2. Choose Instagram Feed Select Instagram Feed from the platform chips.
  3. Download PNG Generate the feed-ready image and download it.

Best practices

  • Use 1080 x 1350 for portrait feed posts.
  • Use a high-resolution source so the final crop stays sharp.
  • Keep the subject centered before exporting.

Common mistakes to avoid

  • Relying on Instagram to crop the photo during upload.
  • Exporting tiny images that become soft after compression.
  • Putting a watermark too close to the edge.
