About Our Audio Tools

Browser-based audio editing and conversion, private by design

What These Tools Are For

Audio arrives in the wrong shape constantly: a voice memo that a transcription service refuses, a WAV recording too big to email, a song that needs to become a ringtone, a lecture recorded so quietly it is unusable, game audio in OGG that a car stereo has never heard of. Each tool on this page handles one of those situations. The converters move files between M4A, MP3, WAV, and OGG; the Trimmer cuts clips and ringtones; the Compressor and Volume Booster fix size and loudness; and Extract Audio pulls the soundtrack out of a video file.

Everything Runs on Your Device

The tools decode audio with the browser's Web Audio API and re-encode with JavaScript libraries running in the page, so your files are processed where they already sit. Nothing is uploaded, which matters more for audio than almost anything else on this site, since recordings are so often private: meetings, interviews, personal notes, unreleased music. It also means no waiting on an upload before work starts, and no server queue when the site is busy.

Frequently Asked Questions

Which converter do I want for iPhone voice memos? M4A to MP3. Voice Memos records in M4A, and converting to MP3 makes the recording playable and uploadable everywhere, including transcription services and older software. For memos that are too quiet, run the result through the Volume Booster afterward.
Is there a file size limit on the audio tools? No fixed limit. Your device does the work, and audio is decoded into memory before processing, so the practical ceiling is your available RAM. Desktops handle album-length files comfortably; very long recordings on older phones are the one case that can struggle.
Do my recordings get uploaded during conversion? No. Decoding runs on the Web Audio API and encoding runs on JavaScript libraries, both inside your browser tab. A confidential meeting recording or a private voice memo is processed without ever leaving the device it was recorded on.
Will converting between formats hurt the audio quality? Converting between lossy formats costs a small amount of detail each time, though a single conversion is inaudible to most listeners. Converting to WAV is lossless but cannot restore detail the source never had. The good habit is to keep your original file and treat conversions as the copies that travel.
Can I make an iPhone ringtone with these tools? Yes, the Audio Trimmer has a ringtone mode that cuts a song to the under-30-seconds Apple requires and exports it ready for import. It is the most popular job in the audio category.
