Feed photos, carousels of up to ten images, and Reels. Never text on its own.
What Duta sends today
Instagram cannot publish a text-only post. Every post needs at least one photo or video, and Duta will not let you schedule one to Instagram without it.
A feed photo and a Reel use different shapes, and Instagram is strict about both, so Duta checks the file against the right one while you are still choosing it.
Carousels of several images are supported, and each image can carry its own description for a screen reader.
The real limits
| Text | Up to 2,200 characters |
|---|---|
| Media required | Yes |
| Photos | Up to 10 per post, 8 MB each, image/jpeg only, shape between 4:5 and 1.91:1 |
| Video | Up to 300 MB, up to 15 min, at least 3 sec, video/mp4 or video/quicktime only |
Worth knowing
- Images must be JPEG. Instagram's publishing API documents JPEG only, and a PNG that looks fine on your screen fails with an error that never mentions the format. Duta refuses it the moment you choose the file rather than after it is scheduled.
- Publishing is a two-step process behind the scenes: the file is handed to Instagram, Instagram is asked to fetch and process it, and only then is it published. Stopping after the first step looks like success and posts nothing.
- Alt text works on photos, not on Reels. Instagram rejects a description on video outright, so Duta never sends one with a Reel.
Connecting Instagram
Instagram is not open for new connections yet — Duta is waiting on the platform to approve access. Nothing already connected is affected. The other channels can be connected now.
