Scheduler
Scheduler → New post:
- Choose the Account and Type (Image, Reel, Video, Carousel).
- Media: drop files in or click Choose from your device. Image takes one photo, Reel and Video take one video, Carousel takes 2 to 10 photos and videos (reorder them with the arrows). Each file is checked against Instagram's rules before you can schedule: Red text blocks scheduling; orange text is a warning you can ignore. Or paste a link to a file adds a public HTTPS link instead; those can't be checked until Instagram publishes them.
- Photos: any photo works and is converted to JPEG. The shape must be between 4:5 (portrait) and 1.91:1 (landscape). A photo that's too tall or too wide shows Crop to 4:5 portrait, Crop to 1:1 square or Crop to 1.91:1 landscape, which crop from the centre. Up to 8 MB after converting. HEIC photos only work in browsers that can open them; on iPhone, Camera > Formats > Most Compatible saves JPEGs.
- Videos: MP4 or MOV, 3 seconds to 15 minutes, up to 300 MB. 9:16 (like 1080 × 1920) fills the screen; other shapes get a warning because Instagram crops them or adds bars. In a carousel, videos can be up to 60 seconds.
- Carousel: every slide is cropped to the first slide's shape, so you get a warning if they differ.
- Write the Caption. Under When, pick Publish now or Schedule for later and a date and time.
- Under Switch these on when it goes live, pick any automations to attach to the post. They're enabled automatically when it goes live.
- Publish now or Schedule. After it's sent, Instagram processes the file before it goes live: a photo takes seconds, a video can take a few minutes. Meanwhile the post shows publishing and "Instagram is processing it", and the list updates by itself. If Instagram is still processing after 30 minutes, or rejects the file, the post shows failed with the reason and a Retry button.
- From the list you can publish a scheduled post right away (Publish now), cancel it, or delete it. A published post shows its picture from Instagram and a View on Instagram link. Uploaded files are kept only until the post is published (a few days after, in case you need them), then deleted.
