Frequently asked questions
How do I convert AIFF to MP3?+
Drop the file here. It is decoded in your browser and encoded to MP3 with the LAME algorithm — then you download the result. No upload, no account, no watermark.
Which bitrate should I choose?+
192 kbps is transparent for most music; 128 kbps is fine for podcasts and speech; 320 kbps is the maximum MP3 allows and best for archiving. Lower bitrates make smaller files.
Will I lose quality?+
MP3 is lossy, so some data is discarded compared with the lossless AIFF original — at 192 kbps and above the difference is inaudible to most people.
Is my file uploaded?+
No. Decoding and MP3 encoding run entirely on your device, so private recordings stay private.
