# What are the character limits and image rules for each social platform?

> Each social platform sets its own text and image rules. Check the limits below before you publish. The app allows one Library image per post and shows a warning when a selected profile needs a change.

These are the rules the app checks for a post. The publish window shows the exact problem beside a profile when a post does not fit.

## Rules shared by all platforms

You can attach one image per post, and it must be in your **Library**. Video and GIF posts are not available. You can choose up to 20 connected profiles for one post. YouTube publishing is a planned feature.

Google Business Profile supports Standard, Event and Offer posts. A call to action that opens a page needs a valid URL. Events need valid start and end dates and times.

## Common questions

### Can I add two images to one post?

No. Choose one image from your Library. More images will be available soon.

### Why does my X link use more space than expected?

The app counts each link as 23 characters toward the 280-character limit.
