Frequently asked questions
Is this audio to MP3 converter really free?
Yes. Completely free for files up to 10MB, 5 uses per day shared across all our tools, no signup and no watermark. Larger files are free too with an Atomiser account (30 monthly credits, no card).
What formats can I convert to MP3?
WAV, M4A, AAC, OGG, FLAC and WMA all work. To pull audio out of a video file instead, use our MP4 to MP3 converter.
What quality is the MP3?
128kbps, which is the standard for speech and most music. It keeps files small enough to share anywhere.
Is my file stored on your servers?
No. Files are processed in memory and temporary files are deleted immediately after conversion completes.
Can I transcribe the audio too?
Yes. Run the MP3 through our free Audio to Text converter, or upload it to Atomiser and get the transcript, captions and clips in one pass.
