# How do I increase the upload limit of st.file_uploader on Streamlit Community Cloud?

## Overview

By default, files uploaded using [`st.file_uploader()`](/develop/api-reference/widgets/st.file_uploader) are limited to 200MB. You can configure this using the `server.maxUploadSize` config option.

Streamlit provides [four different ways to set configuration options](/develop/concepts/configuration):

1. In a **global config file** at `~/.streamlit/config.toml` for macOS/Linux or `%userprofile%/.streamlit/config.toml` for Windows:
   ```toml
   [server]
   maxUploadSize = 200
   ```
2. In a **per-project config file** at `$CWD/.streamlit/config.toml`, where `$CWD` is the folder you're running Streamlit from.
3. Through `STREAMLIT_*` **environment variables**, such as:
   ```bash
   export STREAMLIT_SERVER_MAX_UPLOAD_SIZE=200
   ```
4. As **flags on the command line** when running `streamlit run`:
   ```bash
   streamlit run your_script.py --server.maxUploadSize 200
   ```

Which of the four options should you choose for an app deployed to [Streamlit Community Cloud](/deploy/streamlit-community-cloud)? 🤔

## Solution

When deploying your app to Streamlit Community Cloud, you should **use option 1**. Namely, set the `maxUploadSize` config option in a global config file (`.streamlit/config.toml`) uploaded to your app's GitHub repo. 🎈

For example, to increase the upload limit to 400MB, upload a `.streamlit/config.toml` file containing the following lines to your app's GitHub repo:

```toml
[server]
maxUploadSize = 400
```
