Why MP3 on Android?
Android plays many formats, but music apps, Bluetooth car kits and alarm/ringtone pickers handle MP3 most reliably. Converting odd formats like CAF, AIFF, WMA or M4B to MP3 avoids "unsupported file" errors.
Good to know
Output is MP4 with H.264 video (yuv420p, the colour format every player supports), AAC stereo at 48 kHz, and the index moved to the start of the file so playback and uploads begin immediately.
Supported files
Any common audio or video file: MP4, MOV, MKV, WEBM, AVI and other video formats, and MP3, WAV, M4A, FLAC, OGG, OPUS, WMA and other audio formats. Files up to 1 GB each.
Frequently asked questions
How do I set it as a ringtone?
Copy the MP3 to the Ringtones folder, or use the Ringtone Maker and then pick it in Settings → Sound.
How much does the Android Audio Converter cost?
Nothing. It is free with no registration, no watermark and no limit on how many files you convert.
Are my files safe?
Yes. Files are converted locally in your browser and are never uploaded. When you close the page, nothing is left behind.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
