# Overview

> Filters are used to modify the output of variables and other values.

Filters modify the output of numbers, strings, variables, objects, and arrays. A filter is applied using a pipe character (`|`) followed by the filter name:

```liquid theme={null}
{{ variable | filter }}
```

You can chain multiple filters together, applying one after the other:

```liquid theme={null}
{{ "hello world" | capitalize | upcase }}
```

Some filters can take arguments which are specified after a colon (`:`) character:

```liquid theme={null}
{{ "hello world" | truncate: 5 }}
```

Check detailed documentation for each filter in the following sections:
