- **Password Protection**: A password is required for image encryption and decryption

##### 🔀 Shuffle Only Mode
- **Fragmentation**: Pixels are shuffled across multiple images to help safeguard the original content from unauthorized viewing

#### Preferences

You can customize the extension behavior through the following preferences:

##### Image Protection
- **Type**: Checkbox
- **Default**: `Enabled`
- **Description**: If disabled, images are only shuffled without password protection. If enabled, images require password for decryption.

##### Block Size
- **Type**: Dropdown (1, 2, 3, 4, 8, 16, 32, 64)
- **Default**: `4`
- **Description**: Fragment the image into multiple blocks and shuffle them. Larger block sizes use less memory but provide less fragmentation.

##### File Prefix
- **Type**: Text field
- **Default**: `img`
- **Description**: Set the prefix for encrypted filename.

##### File Name
- **Type**: Checkbox
- **Default**: `Enabled`
- **Description**: Restore the original file name when decrypting.

#### Troubleshooting

> Error: Worker terminated due to reaching memory limit: JS heap out of memory

- Please change the block size to a larger value in the settings.
