# Put your logo, favicon and app icon in place

Your main logo appears throughout Zendo: in the sidebar, on the login screen, on documents, in emails and in forms. You upload it once on **Settings › Brand › Identity**, together with your favicon and app icon. It is best to do this before you invite any clients, because the invitation email shows your logo too.

## Upload the logo and the icons

1. Open **Settings › Brand › Identity**.
2. Upload the **Main logo**. The file can be up to 1 MB.
3. If your main logo does not look right on a dark background, upload a **Dark mode logo** as well. If one logo works in both modes, leave this empty.
4. Under **Logo sizes**, set the logo's width for each place where it appears, and check each one in its **Preview**. The sidebar matters most, because your clients see it every day, so start with **Customize sidebar logo size**. There you can also choose **Full width** or **Use a different width on mobile**.
5. Upload the **Favicon**, the small icon shown in browser tabs. A square PNG works best.
6. Upload the **App icon**, which clients see when they add the client portal to their phone's home screen. The recommended size is 512 × 512 px.
7. To remove the "Powered by Zendo" line from the client portal, turn on **Hide "Powered by Zendo"** (Agency plan only).
8. Check the result in **Live preview**, then select **Save**.

## If you leave an upload empty

Without a main logo, your clients see the Zendo logo instead. Without an app icon, Zendo uses the favicon when a client adds the client portal to their phone's home screen.

## When the dark mode logo is used

Whenever the client portal is in dark mode, the **Dark mode logo** replaces the main logo in the sidebar, on the login screen, on the Front Desk and in forms.

PDFs and emails are the exception: they always use the main logo. So if your main logo only looks right on a dark background, it will look wrong in PDFs and emails.

Whether clients can use dark mode at all is decided by **Color mode** on **Settings › Brand › Appearance**. See [Set your workspace appearance](https://help.getzendo.io/en/article/set-your-workspace-appearance-wobsc5/).

## Places with their own logo setting

Five places can show a logo other than the main one. If one of them shows the wrong logo, check its own setting first:

- **Emails**: **Use a custom logo** or **Hide logo** on **Settings › Brand › Domain & email**. See [Send emails from your own address](https://help.getzendo.io/en/article/send-emails-from-your-own-address-1enl3sm/).
- **Quotes and invoices**: **Use a different logo on documents** or **Hide the logo on invoices and quotes** on **Settings › Sales › Payments & documents › Documents**. See [Set up your documents: numbering, logo, footer and seller details](https://help.getzendo.io/en/article/set-up-your-documents-numbering-logo-footer-and-seller-details-9h73yx/).
- **Sign-up and login pages**: **Use a custom logo** or **Hide logo** on **Settings › Brand › Sign-up & login**. See [Set up the sign-up and login pages](https://help.getzendo.io/en/article/set-up-the-sign-up-and-login-pages-4two6e/).
- **A single form**: the form's own settings.
- **The sidebar, for particular clients**: a client theme on **Settings › Brand › Client themes**. See [Create a client theme](https://help.getzendo.io/en/article/create-a-client-theme-u3u3fz/).
