How It Works
How to Convert GSM
Click inside the file drop area to upload your GSM file or drag & drop it.
Locate your GSM file on your device—typically used for various purposes. Ensure the file is under 50MB to avoid upload issues. If the upload fails, check your internet connection or try compressing the file first.
Choose the format you want to convert your GSM file to and click 'Convert'.
Choose your desired format based on your needs—different formats suit different purposes, like JPEG for smaller file sizes. The conversion process typically takes a few seconds, depending on file size and server load.
Download your converted file instantly after conversion.
Once the conversion is complete, click the download link to save your converted file. You can then open it in software like a compatible viewer. If the file doesn’t download, ensure your browser allows pop-ups from RunConvert.
You can also send a link to the converted file via email. (Optional)
Enter an email address to receive a secure link to your converted file, which is useful for sharing with clients or accessing later. Links expire after 24 hours for security, and RunConvert ensures your data is protected during transmission.

What is GSM (Global System for Mobile Communications Audio)?
GSM (Global System for Mobile Communications Audio) is a specialized audio format developed for mobile telephony. It's a highly compressed format designed specifically for encoding speech at very low bitrates, typically 13 kbps, making it ideal for efficient transmission over cellular networks. GSM files use the .gsm extension.
The GSM audio format prioritizes intelligibility of speech over audio fidelity, using a compression algorithm optimized for human voice frequencies. This results in very small file sizes but with limited frequency response and noticeable artifacts for non-speech audio. Despite its limitations, GSM remains relevant in telecommunications and legacy voice messaging systems.
How to open GSM?
Opening GSM files requires specialized software due to the format's specific purpose in telecommunications. Media players like VLC can handle GSM files with the right codecs installed. For professionals working with telephony systems, specialized tools like Audacity (with GSM plugin) or SOX (Sound eXchange) offer GSM support.
Due to the specialized nature of GSM audio, converting these files to more common formats like WAV or MP3 is often the most practical approach for general use. If you're working with GSM files for telecommunications development or analysis, consider using dedicated telecommunications software that specifically supports GSM audio processing.
GSM is Developed by: European Telecommunications Standards Institute (ETSI)
GSM was Released on: 1991
