Common questions
Why 5 MB?+
5 MB is a common upload cap on forms, messaging apps and email threads. For a voice note, lecture or podcast clip, 5 MB is plenty and gets you under tight limits.
Will it still sound okay?+
We tune the bitrate to the audio's length, so short clips stay crisp. Spoken-word audio compresses especially well; long music tracks have to share 5 MB across more minutes.
Is my audio uploaded anywhere?+
It's uploaded over an encrypted connection, compressed on our server, and both the upload and the result are deleted within an hour. No account, no watermark.
What if it can't fit 5 MB?+
We give you the smallest listenable version and tell you it's just over — for a long track, trim it or pick a larger target like 10 MB.
Which formats work?+
MP3, M4A, AAC, WAV, OGG, FLAC and most common audio files. MP3 comes back as MP3.
