# App Logo

{% hint style="info" %}
This feature is available for **Login, Myinfo (v5), Myinfo Biz (v3) and Sign with Singpass** apps.
{% endhint %}

Your organisation's logo will be displayed in various places like the Login screen and Singpass app. This helps users identify your organisation when they are transacting with you.

### App logo requirement

When uploading your logo, ensure that they meet the following requirements:

* **File format**: PNG (transparent background)
* **Dimension**: 256px by 256px to 512px by 512px
* **File size**: Up to 200KB
* **Aspect Ratio**: Square (1:1 ratio)
* **No padding**: The logo should fill the entire canvas with no surrounding whitespace. Padding is applied automatically and does not need to be included in your upload.

### Example of logo

Note:

* For Singpass app: Logo changes will only be reflected once users update to the latest app version.
* For partners with existing shortcuts in Singpass app: Logo changes or uploaded via SDP will not be reflected on the shortcuts.

### Logo preview during app creation

When creating a new app, a preview of your logo is shown in the first step of the new app wizard. The preview updates as you upload or change your logo.

**Note:** The preview uses a sample logo. Upload your own logo file to see how it will appear on Singpass screens.
{% endhint %}

### Logo pending approval in change requests

When you submit a logo change for a production app, the new logo is not applied immediately — it enters a pending state while the change request is under review. During this review period:

* The current live logo continues to be shown to end users until the change request is approved.

Once the change request is approved, the new logo replaces the current one.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.developer.singpass.gov.sg/docs/getting-started/app-logo.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
