This information mostly applies to email clients that do not support Dark Mode editing. Email clients that support Dark Mode editing give you more control over how your email appears in Dark Mode. Learn more in the Dark Mode Editing article.
Why Dark Mode Impacts Images
Many email clients automatically change background colors in Dark Mode. This usually means light backgrounds become dark.
If your image includes a solid white background baked into the file, that background may become visible in Dark Mode. This can make logos and photos look broken or out of place.
Some email clients support Dark Mode editing. Others do not. If your email client supports Dark Mode editing, you have more control over how your email appears.
Prepare Logos for Dark Mode
Avoid Solid Backgrounds
If your logo includes a white background inside the image file, that background may appear as a visible box in Dark Mode.
This can create poor contrast against darker email backgrounds.

Use Transparent PNG Files
Save logos as transparent PNG files whenever possible. This removes unwanted background colors from the image.
Transparent PNG files work best for logos that already have enough contrast against dark backgrounds.
Watch for Contrast Problems
Transparent logos can create readability issues if the logo itself uses dark colors.
For example:
Black text may disappear against a dark background
Thin logo elements may become difficult to read
Add a Background Treatment to Your Logo
If your logo includes dark elements, add a styled background behind it. This improves readability in both Light Mode and Dark Mode.
For best results:
Add a white panel, shape, or badge behind the logo
Save the final image as a transparent PNG
Leave spacing around the logo edges
This approach keeps the logo readable without creating harsh white boxes in Dark Mode.
Benefits of Background Treatments
Background treatments help you:
Improve readability
Maintain brand consistency
Create a more polished appearance
Prevent unwanted background edges in Dark Mode

Prepare Photos and Marketing Images
Photos and promotional graphics can have similar issues in Dark Mode.
If your image includes a solid white background, that background may become visible after Dark Mode color changes are applied.

Improve Image Appearance in Dark Mode
Option 1: Use Transparent Images
Transparent image files blend more naturally into Dark Mode backgrounds.
This works best when:
The image subject is isolated
The design does not rely on white framing
There is enough contrast around the subject
Option 2: Add Breathing Room
If transparency is not possible, create padding around the image edges. This makes the image feel intentional instead of clipped.
Tips for Better Spacing
Add margins around the image subject
Avoid hard edge cropping
Use soft framing or shadows
Leave consistent whitespace
