Quick answer: To convert GSM to WMA, add the GSM file to the iHateFiles GSM to WMA converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. GSM is a format most software has stopped opening. WMA is not.
Should you convert GSM to WMA?
A safe conversion: GSM and WMA are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
GSM and WMA are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the GSM. The quality ceiling is the codec, not the file. Converting to a higher bitrate cannot add back a frequency range that was never captured.
About the WMA. A WMA bought from an early music store may be DRM-locked, and no conversion can lawfully unlock it. A WMA you ripped yourself converts without any trouble.
How to convert GSM to WMA
- Add your GSM file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WMA.
- Press convert and the WMA file is saved back to your device.
Questions
How do I convert GSM to WMA?
Open this page, add your GSM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this GSM to WMA converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WMA lose quality?
WMA is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several GSM files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
