Fix transparent images in Outlook dark mode

If you upload a transparent image in your email signature, it may appear with a white background in Dark Mode (Outlook).

This happens because Outlook applies its own background rendering in Dark Mode, which can override transparency in images.

Solution: Wrap the image in a table

To preserve the transparent background, place the image inside a table structure. This helps Outlook render the image correctly in Dark Mode.

Step-by-step

1. Open your signature in your Xink account.
2. Click Source.
3. Insert the following HTML structure:

<table border="0" cellpadding="0" cellspacing="0" class="MsoNormalTable">
  <tbody>
    <tr>
      <td>&nbsp;</td>
    </tr>
  </tbody>
</table>

4. Click Source again.
5. Place your cursor inside the table cell and insert your transparent image.

6. Send a test email and verify the result in Outlook Dark Mode.

Result

The transparent image will now render correctly without a white background when viewed in Outlook Dark Mode.

Best Practice

• Always test signatures in Light Mode and Dark Mode
• Use PNG images with transparency
• Avoid relying on background transparency alone for critical design elements
