Your own photos
Drop in any picture from your computer — family, travel, a favorite painting. It’s resized automatically, so Calendar stays fast.
Put your own photos, a different image for every month, or a soft color gradient behind Google Calendar™. Your events stay sharp and readable — in light and dark mode.
No account needed for the free plan · Works in desktop Chrome
Try it — this preview works just like the extension.
Google Calendar gives you colors and a dark mode. Custom Calendar Background gives you the view — without touching your events or your data.
Drop in any picture from your computer — family, travel, a favorite painting. It’s resized automatically, so Calendar stays fast.
Pick a photo for each month and let your calendar change with the seasons, all year long.
Add up to 30 images and wake up to a different background each morning.
Matches Google Calendar’s theme on its own, so text is always crisp — day or night.
A readability layer and blur slider keep busy photos calm behind your events.
A small button in Calendar’s top bar opens a quick panel. Swap images without leaving your calendar.
Choose twelve photos once, and every month opens with a fresh look — snowy peaks in January, the beach in July, warm colors in autumn.
Click the small icon in Google Calendar’s top bar and a quick panel opens right there. Every change shows up behind your calendar instantly.
Install Custom Calendar Background from the Chrome Web Store. It’s free, and it only asks to store your settings.
Choose a photo from your computer, a set of monthly images, or a color gradient. Adjust readability and blur to taste.
Your new background is already there — and it updates instantly whenever you change it.
We built Custom Calendar Background the way we’d want an extension on our own calendar to work: it can’t read your events, it doesn’t track you, and your images are stored only on your device.

Not with Google Calendar’s own settings — it only offers light, dark and event colors. Custom Calendar Background is a Chrome extension that adds what’s missing: a photo, a set of monthly images or a color gradient behind the calendar, while keeping all your events readable.
Yes. The free plan includes your own background image or a color/gradient, automatic light & dark matching, and the readability and blur controls — forever, with no account. Pro adds monthly images and a new background every day, starting at $1.99/month, $9.99/year or $19.99 once. Every Google account can try Pro free for 7 days.
No. Images you add are resized and stored only inside your own browser (Chrome’s extension storage). They are never uploaded to our servers or anyone else’s.
No. The background only changes how Google Calendar looks in your own browser. Your calendar, events and anyone you share them with are not affected.
Yes. The extension detects whether Google Calendar is in light or dark mode and switches its readability layer automatically. You can also force light or dark if you prefer.
At install it only asks for storage (to remember your settings and images) and runs only on calendar.google.com. If you choose to unlock Pro, you sign in with Google so we can link your plan to your email address — nothing else is requested.
It works in desktop Chrome (Windows, macOS, Linux and ChromeOS). Browser extensions can’t change the Google Calendar mobile apps.
Yes. Pro is linked to the Gmail address you sign in with, so it works on every computer where you install the extension and sign in with the same account.
You can cancel a subscription at any time from “Manage subscription” in the extension settings; you keep Pro until the end of the period you paid for. If you’re not happy, email us within 14 days of your purchase for a full refund.
No. Custom Calendar Background is an independent extension. Google Calendar is a trademark of Google LLC.
