You can change your Gmail background in two ways: pick a built-in theme, or upload your own image
Gmail lets you customize the look of your inbox by choosing from preset themes or uploading a personal photo. The background appears behind your email list and doesn't affect how your emails look when you open them. Both options take less than a minute and you can change them back anytime.
The steps differ slightly depending on whether you're using Gmail on a computer or phone. This guide covers the computer version, which gives you the most options.
Key Takeaways
- Gmail's theme settings are in the gear icon menu at the top right of your inbox, under "Themes".
- You can choose from about a dozen built-in themes with different colors and patterns, or upload your own image as a background.
- Your theme choice syncs across all devices where you're signed into that Gmail account.
- Changing your background does not affect your email settings, contacts, or how other people see your emails.
How to pick a built-in Gmail theme
Open Gmail in your web browser and look at the top right corner of the page. Click the gear icon (⚙️) and select Themes from the dropdown menu. A panel will open showing thumbnail previews of all available themes.
Click any theme to see how it looks in your inbox. The change happens instantly. If you don't like it, click a different theme. Once you find one you want to keep, just close the panel — Gmail saves your choice automatically. You don't need to click a "Save" button.
The built-in themes include solid colors like dark gray and light blue, as well as patterns like clouds, mountains, and geometric designs. Some themes are designed to be easier on your eyes in low light, while others are brighter for daytime use.
How to upload your own image as a background
Open the gear icon menu and select Themes. At the bottom of the theme panel, click Upload image. Your computer's file browser will open. Navigate to a photo on your computer and click Open.
Gmail will display your image as the background. If the image is very bright or very dark, the text in your inbox might be hard to read. You can adjust this by going back to Themes and clicking Upload image again to choose a different photo. There's no limit to how many times you can change it.
The image you upload is stored only in your Gmail account. It doesn't get shared with other people, and Gmail doesn't use it for any other purpose. If you delete your Gmail account, the image is deleted too.
What happens to your theme on different devices
When you change your Gmail theme on a computer, the same theme appears on your phone or tablet the next time you open Gmail — as long as you're signed into the same Gmail account. This sync happens automatically and usually takes a few seconds.
If you're signed into multiple Gmail accounts on the same device, each account can have its own theme. Switching between accounts will switch the background too. This can help you tell your accounts apart at a glance.
Troubleshooting: your theme won't change or keeps reverting
If you pick a theme and it doesn't stick, you may be using an older browser or one that doesn't fully support Gmail's newer features. Try refreshing the page by pressing Ctrl+R (Windows) or Command+R (Mac), then pick your theme again.
If you uploaded an image and it's not showing up, the file may be too large. Gmail works best with image files under 5 MB. Try compressing the image using an online tool, then upload it again. If the image still won't upload, try a different file format — JPG and PNG usually work best.
If your theme keeps changing back to the default, you might be signed into Gmail in multiple browser tabs or windows. Close all tabs except one, then change your theme. Multiple active sessions can sometimes cause settings to conflict.
Removing your custom theme and going back to default
Open the gear icon and select Themes. Click the first theme in the list, which is usually labeled as the default or standard Gmail look. This removes any custom image you uploaded and returns Gmail to its original appearance.
You can switch back to a custom theme anytime by following the same steps. Gmail keeps a record of themes you've used before, so they'll appear in your theme list even if you switched away from them.
Frequently Asked Questions
Can I use a video or animated GIF as my Gmail background?
No. Gmail only accepts static image files like JPG and PNG. Animated files won't work as backgrounds. If you try to upload a GIF, Gmail will either reject it or display it as a still image.
Does changing my Gmail theme affect how my emails look when I send them?
No. Your theme only changes what you see in your own inbox. When you send an email, the person receiving it sees only the email content — they don't see your background or theme at all.
What image file sizes work best for uploading?
Gmail works best with images under 5 MB. Most photos from a phone or camera are already this size. If your image is larger, you can compress it using free online tools before uploading.
Can I set a different theme for my Gmail on my phone than on my computer?
No. Your theme syncs across all devices where you're signed into that account. If you want different themes on different devices, you would need to use separate Gmail accounts.
Will my theme stay if I clear my browser's cache and cookies?
Yes. Your theme is saved to your Gmail account, not to your browser. Even if you clear your cache, the theme will still be there when you sign back in.
