# Upload File

Every social media has different terms and conditions for uploading files. For example, Twitter and Facebook available for using text, videos as well as gifs. Meanwhile, Instagram only using a single video or single image for each post. Then, Linkedin only able to upload nine images or a single video for each post. 

We've compiled a detailed list of the terms and conditions for uploading files on each social media. 

| Social Media | Text      | Image  | Video  | GIF   |
| ------------ | --------- | ------ | ------ | ----- |
| Twitter      | 280 char  | 4Mb    | 512 Mb | 15 Mb |
| Instagram    | 2200 char | 8Mb    | 100 Mb | -     |
| Facebook     | unlimited | <4Mb   | <10Gb  | <5Mb  |
| LinkedIn     | 1288 char | <10 Mb | <200Mb | -     |

The following are additional information for image and video duration on each social media:

| Social Media | Video Duration       | Image                      |
| ------------ | -------------------- | -------------------------- |
| Twitter      | 2 minutes 2 second   | -                          |
| Instagram    | 3 second - 60 second | Ratio 4:5 , 1:1            |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.3dolphins.ai/5.1.x/marketing/public-post/create-new-public-post/upload-file.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
