You Need To Add Field In Vendor\Module\view\adminhtml\ui_component\category_form.xml

<fieldset name="general">
 <field name="your_attributte" sortOrder="40" formElement="fileUploader">
 <argument name="data" xsi:type="array">
 <item name="config" xsi:type="array">
 <item name="source" xsi:type="string">category</item>
 </item>
 </argument>
 <settings>
 <elementTmpl>ui/form/element/uploader/uploader</elementTmpl>
 <dataType>string</dataType>
 <label translate="true">Your Label</label>
 <visible>true</visible>
 <required>false</required>
 </settings>
 <formElements>
 <fileUploader>
 <settings>
 <required>false</required>
 <uploaderConfig>
 <param xsi:type="url" name="url" path="route_id/admin_controller_path/controller_file_name"/>
 </uploaderConfig>
 <previewTmpl>Magento_Catalog/image-preview</previewTmpl>
 </settings>
 </fileUploader>
 </formElements>
 </field>
