# Image & Video Editing (Polotno)

> Enable in-app image and video editing in Postiz via the Polotno SDK

Postiz supports in-app image and video editing through the
[Polotno SDK](https://polotno.com/). Once enabled, users can design and
edit visuals directly inside the Postiz workflow while preparing
scheduled posts — no round-trip to an external editor.

## What you get

* Create and edit visuals inside the Postiz post composer.
* Work with templates, text, images, and brand assets.
* Update designs in place without re-uploading finished files.
* Reuse and modify visuals across scheduled posts.

Designs are stored as structured data and rendered when needed.
Scheduling, publishing, and platform-specific logic remain handled by
Postiz.

## Setup

<Steps>
  <Step title="Create a Polotno account">
    Sign up at [polotno.com](https://polotno.com/) and open the
    [API dashboard](https://polotno.com/cabinet/) to generate an
    API key.
  </Step>

  <Step title="Add the API key to Postiz">
    Set `NEXT_PUBLIC_POLOTNO` in your environment to the key from
    the Polotno dashboard:

    ```env theme={null}
    NEXT_PUBLIC_POLOTNO="your-polotno-api-key"
    ```

    In `docker-compose.yaml`:

    ```yaml theme={null}
    services:
      postiz:
        environment:
          NEXT_PUBLIC_POLOTNO: "your-polotno-api-key"
    ```
  </Step>

  <Step title="Restart Postiz">
    `NEXT_PUBLIC_POLOTNO` is read by the frontend at build time, so
    you need to rebuild the frontend image (or restart the dev
    server) for the change to take effect.
  </Step>
</Steps>

Exact steps may vary slightly depending on your deployment — see
[Docker Compose](/installation/docker-compose) or
[Development](/installation/development) for environment-specific
notes. If the variable is unset, the editor falls back to a
demo/anonymous mode that is not suitable for production.
