How do I convert a GSM file to AMR?

Upload your GSM file, choose AMR as the output format, optionally select a bitrate (default 12.2 kbps), and click Convert. Once finished, download the AMR file. The process takes only a few seconds and runs entirely in your browser.

Why convert GSM to AMR instead of keeping the original?

GSM is a fixed 13 kbps telephony codec, while AMR supports adaptive bitrates from 4.75 to 12.2 kbps. Converting to AMR usually produces smaller files and ensures compatibility with modern mobile devices, MMS, and Android media players.

Does GSM to AMR conversion affect audio quality?

Both codecs are lossy and optimized for speech. The conversion decodes GSM audio and re-encodes it in AMR, which can cause generational loss. Sample rate (typically 8 kHz) is preserved, but the final bitrate depends on your chosen AMR setting; lower bitrates shrink file size but may reduce clarity.

Is GSM-TO-AMR free to use?

Yes, GSM-TO-AMR on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?
