# Favicon

> Add a custom favicon to your form so it shows your brand in the browser tab.

## What a favicon is

A favicon is the small icon that appears in the browser tab when a respondent has your form open. By default, the Filla favicon is shown. You can replace it with your own brand icon.

## How to set a favicon

<Steps>
  <Step title="Open the Form Settings Sidebar">
    In the form editor, click anywhere on the canvas background (not on a field) to open the form-level settings in the right panel.
  </Step>

  <Step title="Find the Favicon setting">
    Look for the **Favicon** upload field in the appearance section.
  </Step>

  <Step title="Upload your favicon">
    Click the upload area and select your favicon file. Supported formats: ICO, PNG, SVG.
  </Step>
</Steps>

## Favicon requirements

* **Recommended size:** 32x32px (standard favicon size)
* **Supported formats:** ICO, PNG, SVG
* **Square dimensions:** Favicons must be square or they may display oddly in some browsers

<Tip>
  Use a PNG or SVG version of your logo mark (the icon portion, not the full wordmark). A 32x32px square works best. ICO format is the most universally supported, but PNG and SVG work fine in modern browsers.
</Tip>

## Where the favicon appears

* In browser tabs when the form is open
* In browser bookmarks if a respondent bookmarks the form
* In browser history

The favicon appears in both the standalone form view and embedded forms (the tab icon is controlled by the parent page when embedded).

## Common questions

<AccordionGroup>
  <Accordion title="My favicon isn't updating. Why?">
    Browsers aggressively cache favicons. After uploading a new one, clear your browser cache or open the form in a private/incognito window to see the new favicon.
  </Accordion>

  <Accordion title="Can I use an animated GIF as a favicon?">
    Technically the browser may show the animation, but it is generally not recommended. Animated favicons can be distracting. Use a static PNG or ICO instead.
  </Accordion>

  <Accordion title="Does the favicon show when the form is embedded?">
    No. When your form is embedded in another website, the browser tab shows the favicon of the parent page, not the Filla form's favicon.
