# Materials & Files

> Upload reference files, paste images, or generate custom materials with AI

## Reference Files

Upload documents as source material — AI references the extracted content when generating outlines, descriptions, and images.

When parsed documents contain images, those images are automatically added to the project's material library once the reference file is associated with a project, so you can reuse them later from the material picker.

### Supported Formats

| Format           | Extracted Content              |
| ---------------- | ------------------------------ |
| PDF              | Text + embedded images         |
| DOCX / DOC       | Document content and structure |
| PPTX / PPT       | Slide content                  |
| XLSX / XLS / CSV | Spreadsheet data               |
| Markdown / TXT   | Plain text                     |

<Tip>
  PDF parsing uses [MinerU](https://mineru.net) for high-quality extraction. Configure a MinerU token for better results — see [Configuration](/configuration#mineru-pdf-parsing).

### Upload Methods

* Click the **paperclip icon** next to the input area to open a file picker
* **Drag and drop** files into the input area
* **Paste** (Ctrl+V) files or images from clipboard
* Click **Material Center** to select from previously uploaded files

File size limit: **200MB**. Files parse automatically after upload and show "Parsing" status until complete.

### Where to Upload

| Location                         | Notes                                                           |
| -------------------------------- | --------------------------------------------------------------- |
| Home page                        | Upload before creating a project — applies to the whole project |
| Outline Editor                   | Manage files in the left panel                                  |
| Description Editor               | View and manage files in the top section                        |
| Slide Preview (single-page edit) | Attach a reference image to one specific page                   |

## Pasting Images

Paste an image anywhere (Ctrl+V) in the home page, Outline Editor, or Description Cards:

1. Copy an image (screenshot, copy from web, etc.)
2. Press **Ctrl+V** in the input area
3. The image uploads automatically — AI recognizes its content and inserts it as a Markdown image reference at the cursor position

## Style References

Upload an image as a visual style reference — AI will match its color palette, layout patterns, and design language.

Upload in the **Select Style Template** section on the home page, or in the **Upload Images** section of single-page editing.

## Material Toolbox

Click **Generate Material** in the top navigation bar to open the unified **Material Toolbox**. It now covers more than prompt-to-image generation: you can also take an existing image, edit the whole frame, edit a selected region, or erase content from a selected region.

### Generate

Use this mode to create a brand-new image from text:

1. Enter a prompt such as `Blue-purple gradient background with geometric shapes and tech-style lines`
2. Pick an aspect ratio
3. Optionally add a primary reference image and extra references
4. Click **Run Tool**

### Full Image Edit

Use this mode when you already have an image and want to restyle or rewrite the whole frame:

1. Choose a **Source Image**
2. Enter an instruction such as `Restyle the image with brushed silver metal while keeping the main composition`
3. Optionally add reference images
4. Click **Run Tool**

### Region Edit

Use this mode when only part of the image should change, such as a CTA, title block, object, or foreground detail:

1. Switch to **Region Edit**
2. Load a source image
3. Click **Start Selection** and drag over the area to change
4. Enter the edit instruction
5. Choose how the result should be applied:
   * **Overlay only the selected region**: keep the unselected area as stable as possible and only patch the selected area back into the original image
   * **Replace with the full generated image**: still focus the edit on the selected area, but use the model's full-frame output as the final result
6. Click **Run Tool**

### Smart Erase

Use this mode to remove logos, watermarks, clutter, or other unwanted elements:

1. Switch to **Smart Erase**
2. Load a source image
3. Select the region to remove
4. Optionally add a short note for what should fill the erased area, such as `clean light gray stone texture`
5. Click **Run Tool**

### Continue Editing

After a run completes, click **Use result as new source** to send the latest output back into the toolbox for another pass. This works well for flows like:

* erase first, then refine a local area
* restyle the whole image, then polish one component
* generate a material, then keep iterating on details

Every processed result is saved as a **new material** in the library. The original source image is not overwritten.

## Material Center

Click **Material Center** in the top navigation bar to manage all materials:

* **Filter**: By project, or view all / unassociated materials
* **Preview**: Click the eye icon for fullscreen preview
* **Download**: Select items and download — multiple files are packaged as ZIP
* **Delete**: Individual or batch delete
* **Upload**: Add new images directly from Material Center
