What is supported

  • Feed image posts (JPEG, or PNG/WebP/GIF converted to JPEG at publish).
  • Carousel posts with several images (same image types).
  • Reels (video).
  • Stories (one image or one video). Images convert to JPEG at publish. Meta does not accept a story caption.
  • Captions and alt text (feed, carousel, and Reels).
  • Scheduling and publishing right away.

Gotchas

  • Instagram needs media on every post, so add at least one image or video.
  • Meta only accepts JPEG images. We convert PNG, WebP, and GIF (first frame) when the post publishes. The gallery original is unchanged.
  • Reels and other videos can take a few minutes for Instagram to process. A timeout is not a broken connection — we keep waiting and retry the same container.
  • Instagram access lasts a long time but is refreshed automatically. If it disconnects, reconnect from the Connect screen.
