Does Telegram Support Open Graph? Complete Guide To Solve Problem

ByTB-Team

The content sharing and marketing space in the digital world today simply cannot be ignored without social media. The one technology that really upgraded the sharing experience is Open Graph, or OG for short. It’s a protocol that gives websites a chance to control how their website content is rendered upon sharing on social media. It is indeed really visually appealing with rich snippets, images, and descriptions. Does Telegram support Open Graph?

Telegram is one of the best messaging applications that is characterized by security, speed, and feature-packed environments. When it comes to Open Graph integration, however, things might not be as simple. Here, we’ll look deep into how Telegram handles Open Graph, what limitations might exist, and what you can do if you’re facing issues with OG tags in your Telegram links.

What Is Open Graph?

Before diving into the specifics of Telegram, let us briefly discuss what Open Graph is. Open Graph is a protocol developed by Facebook that lets the developers define how a web page shared would look across social media sites. You could add Open Graph tags inside the HTML of any webpage to let it specify:

  • The title of the content
  • The description
  • The image that should be displayed
  • The URL of the webpage

These elements make the link visually appealing, encouraging more clicks and engagement.

How Does Open Graph Work in Messaging Platforms?

Many messaging apps and social platforms (like Facebook, Twitter, LinkedIn, etc.) use Open Graph data to create link previews. When a user shares a link, the platform fetches the Open Graph metadata from the web page and displays it as a rich snippet with an image, title, and description.

The key question is: Does Telegram support this functionality?

Does Telegram Support Open Graph?

Yes, Telegram does support Open Graph to a certain extent. When you share a link in a Telegram chat, the app automatically tries to fetch the OG tags and display a link preview, including an image, title, and description. However, there are some nuances and limitations that can affect how well this works.

Telegram’s Use of Open Graph Tags

Telegram uses Open Graph metadata to create link previews, but its implementation isn’t as robust as some other platforms. Here’s how it works in practice:

  1. Basic Link Previews: When a link containing Open Graph tags is shared in a Telegram chat, the platform will attempt to generate a link preview based on the OG metadata. The preview typically includes:
    • The title (from the og:title tag)
    • A short description (from the og:description tag)
    • An image (from the og:image tag)
  2. Fallback Behavior: If a web page doesn’t have Open Graph tags, Telegram will try to generate a preview using other metadata, like meta description or the page title. If no suitable metadata is found, the link may not display a preview at all.
  3. Supported Formats: Telegram generally supports standard Open Graph tags like:
    • og:title (Title of the page)
    • og:description (Brief description)
    • og:image (Image URL)
    • og:url (Canonical URL)
  4. Image Sizes: One key issue with Telegram’s support for Open Graph is its handling of images. Telegram requires images to meet specific size requirements (at least 300×200 pixels). If the image doesn’t meet this size, Telegram might not display it in the link preview.

Common Problems with Open Graph in Telegram

Despite Telegram’s general support for Open Graph, users sometimes encounter problems. Here are some of the most common issues and how you can solve them:

1. No Link Preview Displayed

  • The Issue: You’ve shared a link in a Telegram chat, but no preview (title, description, or image) is generated.
  • Possible Causes:
    • The website lacks Open Graph tags.
    • The website has incorrectly implemented OG tags (e.g., missing og:image, og:title, or og:description).
    • Telegram’s cache hasn’t updated.
  • Solution:
    • First, check the website’s source code to ensure the OG tags are properly set up. You can use online tools like the Facebook Sharing Debugger to check for errors.
    • If the website has recently added Open Graph tags, Telegram might still be showing a cached version of the link. You can wait for Telegram’s cache to refresh (this might take some time), or try adding a query parameter (e.g., ?refresh=true) to the URL to force Telegram to fetch a new version.

2. Image Not Displayed

  • The Issue: The title and description are showing, but the image isn’t.
  • Possible Causes:
    • The image in the og:image tag doesn’t meet Telegram’s size requirements (at least 300×200 pixels).
    • The image format isn’t supported (Telegram prefers JPEG or PNG).
    • The image URL is inaccessible due to server restrictions.
  • Solution:
    • Ensure the image meets Telegram’s size requirements (minimum 300×200 pixels, but larger images tend to work better).
    • Check if the image is in a supported format (prefer JPEG or PNG).
    • Ensure the image is accessible via a direct URL without any restrictions (no login required).

3. Outdated Previews

  • The Issue: You’ve updated a webpage’s OG tags, but Telegram still shows the old title, description, or image.
  • Possible Causes:
    • Telegram has cached the old preview and hasn’t refreshed it.
  • Solution:
    • Similar to the no preview issue, Telegram’s cache might take time to update. You can try appending a unique query string (e.g., ?update=true) to force a fresh fetch of the page.

4. Slow or Incomplete Previews

  • The Issue: Telegram takes a long time to generate a preview, or the preview appears incomplete.
  • Possible Causes:
    • The web server hosting the page might be slow to respond.
    • The OG tags might be located too far down the HTML code, making it harder for Telegram to fetch them quickly.
  • Solution:
    • Improve the speed and performance of the website, ensuring that the Open Graph tags are included early in the page’s HTML (ideally in the <head> section).
    • Minimize server response times and optimize the page load speed.

How to Ensure Your Links Work Well with Telegram

If you’re a website owner or developer and want to make sure your links display correctly in Telegram, follow these best practices:

  1. Properly Implement Open Graph Tags: Ensure your pages have the necessary OG tags (og:title, og:description, and og:image). Double-check that these tags are correctly formatted.
  2. Optimize Images for Telegram: Use images that meet Telegram’s size requirements. A good rule of thumb is to have an image that’s at least 1200×627 pixels, similar to what works well for Facebook.
  3. Test Your Links: Use tools like the Facebook Sharing Debugger or OpenGraph.xyz to test how your links will appear across platforms.
  4. Be Patient with Cache Issues: If you update the Open Graph tags, give it some time for Telegram to refresh its cache. In the meantime, you can try using unique query parameters to force a fresh fetch.

Conclusion

So, does Telegram support Open Graph? Yes, but with some caveats. While Telegram does generate link previews using OG tags, the experience isn’t always perfect, especially when it comes to image sizes and cache issues. If you’re a website owner or developer, ensuring your Open Graph implementation is solid can go a long way in improving how your content looks when shared on Telegram. And if you’re a user experiencing issues, understanding these limitations can help you troubleshoot problems quickly.
