Fetching User Avatars as JPEG with Discord OAuth2 in PHP

Discord has become one of the most popular platforms for community interaction, and integrating its OAuth2 login into your website can streamline user authentication. However, you might run into challenges when trying to retrieve user avatars in specific formats, like JPEG. In this guide, we’ll explore how to achieve that effortlessly using PHP.

The Challenge

While working on a Discord OAuth2 login for your website, you may need to display user avatars in JPEG format. The default avatar format returned by Discord can vary (like PNG or GIF), and sometimes you simply want it in JPEG to maintain consistency across your platform.

For instance, you might have come across code that helps you set up OAuth2, but it doesn't directly facilitate changing the avatar image format as you would like. Here’s the typical OAuth2 request setup you might encounter:

While this code initiates the user authentication process, what comes next? How do you retrieve the avatar, and how can you ensure it's in the JPEG format? Let's break it down.

Solution: Retrieving the Avatar and Changing Its Format

Once you have successfully authenticated the user and received their data, including the avatar, you will want to construct the URL for the avatar image. Here’s how to do that step-by-step:

1. Obtain User Data

Confirm that you can access user data, including the avatar ID. This data is typically obtained from your OAuth2 request.

2. Formulate the Avatar URL

Discord utilizes a CDN (Content Delivery Network) to host user avatars. You can construct the URL based on the user’s ID and avatar hash received from the OAuth2 response.

Example Format for PNG

Changing to JPEG

To convert the image format to JPEG, simply change the .png at the end of your URL to .jpg. This is how you do it:

3. Consideration of Size

Discord allows you to specify the image size as well. You can append a query string for size by adding ?size=desired_size at the end of the URL:

Summary of Key Steps

Authenticate users using Discord OAuth2 and retrieve user data.

Construct the avatar URL using the user’s ID and avatar hash.

Change the format from .png or .gif to .jpg as needed.

Specify the desired size of the avatar in the URL for better presentation.

Conclusion

Transforming avatar images into JPEG format using Discord's OAuth2 integration in PHP is straightforward once you understand the URL structure needed. By following the steps outlined above, you can ensure a consistent display of avatars across your platform regardless of their original format.

With your newfound knowledge, you should be able to enhance the user experience on your website by implementing these avatar retrieval techniques effectively. Happy coding!
