# File size, resolution and format

## **Which image formats are supported?** <a href="#q-what-are-the-max-resolution-and-size-of-the-image" id="q-what-are-the-max-resolution-and-size-of-the-image"></a>

For the input and result images, the Image Editing API supports three formats: PNG, JPEG and WEBP.

By default, the result image will be in PNG format.

To configure the format of the result image, set the argument `export.format` with one of the following values:

* `png` for PNG format (bigger file size, transparency is saved)
* `jpeg` or `jpg` for JPEG format (smaller file size, transparency is not saved)
* `webp` for WebP format (smaller file size, transparency is saved)

{% hint style="info" %}
Both JPEG and WebP export with a quality of 90
{% endhint %}

{% hint style="warning" %}
JPEG format does **not** support transparency.&#x20;

Asking the Image Editing API to export in JPEG while also setting a background color with transparency will result in an error.
{% endhint %}

If you want to give it a try, here's the code to export an image in JPEG format:

{% code overflow="wrap" %}

```bash
curl --request POST \
  --url https://image-api.photoroom.com/v2/edit \
  --header 'x-api-key: YOUR_API_KEY' \
  --form imageFile=@/path/to/your/image.jpg \
  --form background.color=FFFFFF \
  --form outputSize=1000x1000 \
  --form padding=0.1 \
  --form 'export.format=jpeg' \
  --output result.jpeg
```

{% endcode %}

<a href="https://try-api.photoroom.com/?background.color=FFFFFF&#x26;outputSize=1000x1000&#x26;padding=0.1&#x26;export.format=jpeg" class="button primary">Try it now!</a>

And here's the code to export an image in WebP format:

{% code overflow="wrap" %}

```bash
curl --request POST \
  --url https://image-api.photoroom.com/v2/edit \
  --header 'x-api-key: YOUR_API_KEY' \
  --form imageFile=@/path/to/your/image.jpg \
  --form background.color=FFFFFF \
  --form outputSize=1000x1000 \
  --form padding=0.1 \
  --form 'export.format=webp' \
  --output result.webp
```

{% endcode %}

<a href="https://try-api.photoroom.com/?background.color=FFFFFF&#x26;outputSize=1000x1000&#x26;padding=0.1&#x26;export.format=webp" class="button primary">Try it now!</a>

## **What are the max resolution and size of the image?** <a href="#q-what-are-the-max-resolution-and-size-of-the-image" id="q-what-are-the-max-resolution-and-size-of-the-image"></a>

We recommend limiting images to 25 megapixels for optimal performance.

* **Maximum File Size**: 30MB
* **Maximum Resolution**: 5,000 pixels on the widest side

Images with a larger resolution are supported (if they stay below 30MB), but will be resized down to 5,000 pixels on the widest side.

{% hint style="info" %}
Please note that large images will result in API calls taking a longer time to complete.

If you experience timeouts, we recommend that you try to increase the default timeout of your networking library.
