# Defaults & presets
In certain situations you may want to define default image manipulations. For example, maybe you want to specify that all images are outputted as JPEGs (`fm=jpg`). Or maybe you have a watermark that you want added to all images. Glide makes this possible using default manipulations.
~~~ php
[
'mark' => 'logo.png',
'markw' => '30w',
'markpad' => '5w',
]
]);
// Set using setter method
$server->setDefaults([
'mark' => 'logo.png',
'markw' => '30w',
'markpad' => '5w',
]);
~~~
## Presets
Glide also makes it possible to define groups of defaults, known as presets. This is helpful if you have standard image manipulations that you use throughout your app.
### Configuring presets
~~~ php
[
'small' => [
'w' => 200,
'h' => 200,
'fit' => 'crop',
],
'medium' => [
'w' => 600,
'h' => 400,
'fit' => 'crop',
]
]
]);
// Set using setter method
$server->setPresets([
'small' => [
'w' => 200,
'h' => 200,
'fit' => 'crop',
],
'medium' => [
'w' => 600,
'h' => 400,
'fit' => 'crop',
]
]);
~~~
### Using presets
To use a presets, set it using the `p` parameter:
~~~ html
~~~
It's also possible to use multiple presets together:
~~~ html
~~~
It's even possible to use presets with additional parameters:
~~~ html
~~~
## Overriding defaults and presets
You can override the default and preset manipulations for a specific request by passing a new parameter (e.x. `mark=different.png`), or even disable it entirely by setting it to blank (e.x. `mark=`).
