Connect the Instagram account that can publish for your brand, then select its profile as a channel. Check the image requirements before composing.

Check the account and post limits
Instagram posts need at least one image or video and their captions are limited to 2,200 characters. Images are JPEG, up to 20 items, and 8 MB each. The app checks the image shape from 4:5 through 1.91:1. Captions are plain text; links typed into the caption are not clickable. Video is stored by SME but the current publisher does not post it.
Connect the right account
You need a professional Instagram account, either Business or Creator. A personal account cannot be used as a publishing channel. SME asks you to sign in on the platform’s own page and approve the requested access. Your password is not entered into SME.
Add Instagram to SME
- Open Connect, then Logins.
- Choose Add a login, then select Instagram.
- Complete the platform’s sign-in and permission screen.
- Return to SME and open Connect, then Channels.
- Select the professional account under Where to post, assign it to your brand and save the selection.
- In Compose, choose the channel and check the preview and any warning before saving.
Common questions
Why was my PNG changed?
Instagram accepts JPEG images in this app. SME converts a PNG to JPEG during image preparation, so check the resulting preview before saving.
