To add the small favicon-like image shown in browser tabs, bookmarks, and some mobile app contexts, set WordPress’s Site Icon—not merely the page-level logo. Prepare a square image at least 512 × 512 pixels (PNG is the format recommended in WordPress’s current guide), then choose the settings route that matches your WordPress version and active theme.
WordPress 6.5 and newer generally use Settings > General. An activated block theme provides Appearance > Editor > Identity. Older installations and compatible classic themes use Appearance > Customize > Site Identity.
Choose the right WordPress route first
The menu you need depends on two things: your WordPress version and whether the active theme is a block theme. Do not keep looking for the Customizer if your site is using a block theme; that theme normally puts identity controls in the Site Editor instead.
| Site condition | Where to set the icon | What to save |
|---|---|---|
| WordPress 6.5 or later | Settings > General | Complete the Site icon change in General Settings |
| Activated block theme | Appearance > Editor > Identity | Save the Site Editor change |
| WordPress 4.3–6.4 with a compatible classic theme | Appearance > Customize > Site Identity | Click Publish in the Customizer |
WordPress’s official documentation says version 6.5 moved the site icon to General Settings. The Site Editor Identity panel is available only when a block theme is installed and activated. A theme, plugin, host customization, or later WordPress release can change the labels you see, so use the closest matching route rather than forcing a missing menu.

Prepare the image before uploading
Meet the minimum dimensions
Use a square image that is at least 512 × 512 pixels. WordPress’s current guide recommends PNG for this purpose. A square canvas prevents the icon from being unexpectedly cropped when it is rendered at tiny sizes.
Design for a tiny display
- Use a simple mark with strong contrast; fine text often becomes unreadable in a tab.
- Leave enough padding that the main shape is not cut off by rounded or platform-specific masks.
- Check that the artwork remains recognizable when reduced to a small square.
You can upload an image directly from the Site icon control or select one already in the Media Library. Setting a page logo alone does not automatically configure the Site Icon.
Add the icon in WordPress 6.5 or later
- Sign in to the WordPress administrator area.
- Open Settings > General.
- Find the Site icon control.
- Choose an image from the Media Library, or upload your prepared square image and select it.
- Complete the save action presented by that screen.
This is the current general route for WordPress 6.5 and newer. If you do not see the control, check the active theme: a block theme may expose the same setting through the Site Editor Identity panel described next.
Use the Site Editor with a block theme
The Identity menu is conditional: it appears only when a block theme is active. This is the route to use when Appearance > Customize is absent on a modern block-theme site.
Recommended Free Tools
- Confirm that a block theme is installed and activated.
- Go to Appearance > Editor.
- Select Identity in the Site Editor sidebar.
- Under the Site Icon control, choose an existing Media Library image or upload a replacement.
- Save the Site Editor changes.
The Identity panel independently documents the same 512 × 512 pixel minimum. If the Identity item is missing, verify that the site really uses a block theme and that your account has permission to edit the site.
Use the Customizer with an older or classic-theme site
For WordPress 4.3 through 6.4, the documented path is the Customizer. A compatible classic theme must expose the relevant controls.
- Open Appearance > Customize.
- Choose Site Identity.
- Select Site Icon.
- Pick an image from the Media Library or upload your square image.
- Click Publish to apply the change.
The Customizer is theme-dependent and is generally hidden for block themes unless a plugin or theme specifically activates it. Therefore, a missing Customize menu is not by itself an installation error.
Site Icon and Site Logo are different settings
A Site Icon is the small identity image associated with the site. Browsers can show it in tabs and bookmarks, and operating systems or web apps may use it in shortcuts. A Site Logo is normally a page-level image rendered in the website layout.

Rank #3
You may use the same artwork for both, but configuring the logo does not inherently set the icon. In a block theme, select the Site Logo block and turn on Use as site icon in its block settings when you want that logo image to become the Site Icon as well.
Save, then check the result without assuming a fixed update time
After saving, open the public site in a browser tab and inspect a bookmark or shortcut view where your browser displays site icons. The official setup instructions do not promise a universal propagation time, so do not treat an immediate change—or a delay—as proof that the setting failed.
- Reopen the page in a private window to reduce the chance that an old locally cached icon is being displayed.
- Check the site in a second browser or device if the first one still shows the previous image.
- Confirm that you completed the final Save or Publish action; selecting an image without saving leaves the old setting in place.
- Return to the same WordPress route and verify that the chosen image is still selected.
Troubleshoot the common failure modes
“I cannot find Site Identity”
First determine whether the site uses a block theme. With a block theme active, open Appearance > Editor > Identity. The Customizer is not normally the primary identity interface in that setup.
“Appearance > Customize is missing”
That can be expected for a block theme. Use the Site Editor route. On a classic theme, a plugin, theme setting, or host customization may have changed which menus are available; confirm the active theme and its supported controls.

“The Site Icon control is missing from General Settings”
Check the WordPress version and theme type. WordPress 6.5 moved the control to General Settings, while a block theme can provide the Identity panel in the Site Editor. Also verify that you are editing the intended site and have administrative access.
“The image is rejected or looks cropped”
Use a square file that is at least 512 × 512 pixels, preferably PNG as recommended by WordPress. Re-export the artwork with a square canvas and adequate padding, then replace the selected image.
“The old icon still appears”
Make sure the change was saved or published, then test in a private window or another browser. Different browsers and devices can retain an earlier icon independently; the setup documentation does not specify a guaranteed refresh interval.
“My logo changed but the tab icon did not”
Logo and Site Icon settings are separate. Set the Site Icon explicitly, or, in the Site Logo block settings for a block theme, enable Use as site icon.

If you need an automated screenshot of the finished site for a deployment check or documentation, ScreenshotNeo can capture the page through one HTTP request. It is a website screenshot API and MCP server; its clean-shot workflow accepts consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and each response reports the page verdict and billing status in headers.
After you have configured the WordPress icon, replace https://stripe.com below with your public site URL. The complete option list and response details are in the ScreenshotNeo documentation.

Final decision
Use Settings > General on WordPress 6.5+, Appearance > Editor > Identity with an activated block theme, or Appearance > Customize > Site Identity on a compatible older/classic setup. A square 512 × 512-or-larger PNG, an explicit save, and a separate check of the Site Icon setting are the essentials.
