What is a TGS file?
A .TGS file is a Telegram Animated Sticker File. Telegram Messenger uses this format to send high-quality vector animations in chats. These files provide smooth animations at 60 frames per second while keeping file sizes extremely small.
How to open TGS files?
The easiest way to open a .TGS file is to send it in a chat using the official Telegram application. Because the format is based on Lottie animations, developers can also preview these files using Lottie web players. Internally, the file contains JSON code that is compressed using GZIP.
Best practices and troubleshooting
Do not rename the .TGS file extension. If you want to see the source code of the animation, you can extract the file using an archive tool like 7-Zip or WinRAR. This will reveal the raw JSON data, but you will not see the visual animation.
Software and tools
Designers create .TGS files using Adobe After Effects and a specific plugin called Bodymovin-TG. If you need to use the animation outside of Telegram, you should convert the file. We recommend converting your file on convert.guru. The best target formats for broad compatibility are .GIF or .WEBP.
Summary
viewer.online/tgs analyzes .TGS files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If your file is not a standard sticker, viewer.online/tgs can identify the actual format of your file. Because standard .TGS files use the known JSON format inside a GZIP container, viewer.online/tgs can safely open and display them online, eliminating compatibility problems.
