How it works

    Add your audio

  2. 02

    We aim for 5 MB

    We read the length and pick the bitrate that lands the file near 5 MB, re-encoding it to keep it as clear as the budget allows.

  3. 03

    Download & send

    Grab the compressed audio, ready to email or upload anywhere with a 5 MB cap.

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 after 1 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.
