Gravatar Generator

What Is a Gravatar Generator?

A Gravatar Generator creates a Gravatar image URL from an email address. Gravatar uses an MD5 hash of a normalised email address to identify the avatar associated with that address. The resulting URL can be requested by websites and applications that support Gravatar.

This tool is useful for developers, website owners, bloggers and anyone who needs to construct a Gravatar image URL without manually calculating the required email hash and URL parameters.

Why Use the Gravatar Generator?

The generator handles the URL construction and MD5 hashing in your browser, making it straightforward to create a Gravatar URL with the settings you need.

How to Use the Gravatar Generator

Generate a Gravatar URL in a few steps using the options provided by the tool.

1. Enter an email address — Enter the email address associated with the Gravatar account.
2. Choose the image size — Select the dimensions you want the Gravatar service to request.
3. Set the rating and default image — Choose the maximum content rating and fallback image.
4. Generate and copy the URL — Click the generate button, review the preview and copy the resulting Gravatar URL.

Generate a Gravatar URL Online

A Gravatar URL identifies an avatar through a hash of the user's email address. To create the hash, the email address is normalised by removing leading and trailing whitespace and converting it to lowercase before being processed with MD5. The resulting hexadecimal hash forms part of the Gravatar image address.

The generated URL can also include parameters that control the requested image size, content rating and fallback image. This makes the URL suitable for different website layouts and applications while allowing a predictable image to be returned when no Gravatar is associated with the supplied email address.

How Gravatar Email Hashing Works

Gravatar does not place the original email address directly in the avatar URL. Instead, the normalised email address is converted into an MD5 hash. The hash is then used by the Gravatar service to locate the corresponding avatar. This generator performs that hashing locally in the browser.

Using a Gravatar URL in HTML

A generated Gravatar URL can be placed in the src attribute of an HTML img element. The tool also provides a ready-made HTML example so that the generated address can be incorporated into a website more easily.

Gravatar URL Options and Limitations

The size parameter determines the requested avatar dimensions. Gravatar supports requested image sizes from 1 to 2048 pixels. This tool provides commonly used sizes through the interface, while the generated URL remains compatible with standard Gravatar image URL parameters.

The tool generates the URL locally and does not determine whether an email address has an existing Gravatar account. The preview is requested from the Gravatar service after the URL has been generated, so the availability of an avatar depends on the external Gravatar service and the supplied email hash.
