# 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
```
