Instagram direct publishing on professional accounts (Business/Creator) is a great improvement, however, there are a couple of technical limitations you should be aware of. Based on the official docs, we list the most important limitations here:
Images
The image must:
be within a 4:5 to 1.91:1 aspect ratio range
have a minimum resolution of 150x150px (lower resolutions will be scaled up to minimum requirements)
have a maximum resolution of 1920x1080px (higher resolutions will be scaled down to maximum requirements)
JPEG file format
Note: It's not possible to customize the image with Instagram filters - customizing images with Instagram filters is only possible when publishing via the Instagram mobile app
Transparent .PNG files - transparent pixels are going to be "converted" into black pixels - this is a limitation of the Instagram API
Videos
between 16:9 and 4:5 aspect ratio
have a maximum resolution of 1920px (horizontal)
MOV and MP4 file formats
Duration: min 3 seconds/max 59 seconds
Reels

Note: It is possible to publish Reels longer than 89sec. However, Reels with a duration between 89sec - 15 minutes long will not appear in the Instagram Reels tab. We display a warning about this when you create the post. More on publishing Instagram Reels here.
