Audio tools handle the sound jobs that come up every day: a voice memo in the wrong format, a song to cut into a ringtone, a recording too quiet to hear. On ToolPeko they run inside your browser. Your audio is never uploaded, and every tool is free.
Every tool below runs in your browser, on your own device. Open one, finish the job, close the tab. Nothing you use here is uploaded or stored.

Sound files cause their own small troubles. The voice memo is in a format nothing opens, the interview is too quiet, the ringtone you want is buried in the middle of a song. This page is the drawer those jobs live in.
Format swaps: Audio Converter moves between MP3, WAV, M4A and OGG in one box. The pairs people ask for by name are here too: WAV to MP3 for heavy recordings, M4A to MP3 for voice memos and iTunes files, MP3 to WAV, OGG to MP3, FLAC to MP3 and MP3 to OGG.
Cutting and joining: MP3 Cutter takes the part of a song you want and drops the rest. Split Audio cuts one long recording into separate parts, and Merge Audio joins clips end to end into a single file. Ringtone Maker is the cutter aimed at one job: the best 30 seconds of a song, ready for your phone.
Fixing sound: Increase Volume makes a quiet recording loud enough to hear. Normalize Audio brings loud and quiet parts to one even level, Compress MP3 makes a smaller file that still sounds like the song, and Audio Speed Changer speeds a lecture up or slows a song down. Reverse Audio plays a sound backwards, and BPM Finder reads the tempo of a song in beats per minute.
Voice, both directions: Voice Recorder records straight from your microphone and saves the file to your device. Text to Speech reads typed words aloud in your browser’s own voice, and Speech to Text listens and writes your words down.
| Your problem | Use this | Why it fits |
|---|---|---|
| My voice memo will not play anywhere | M4A to MP3 | MP3 is the format everything opens |
| I want this chorus as my ringtone | Ringtone Maker | Cuts the exact seconds and sizes them for a phone |
| The recording of the meeting is too quiet | Increase Volume | Raises the level so voices can be heard |
| Some parts shout and some whisper | Normalize Audio | Evens the whole file to one level |
| A two hour lecture is really three topics | Split Audio | Separate files you can name and share |
| These clips belong in one file | Merge Audio | Joined end to end, in your order |
| I need to dictate a note, hands free | Speech to Text | Your words appear as text as you speak |
| This FLAC album will not fit on my phone | FLAC to MP3 | Same songs, a fraction of the size |
On most audio sites your file is uploaded, processed on a server, and downloaded back. Here the cutting, converting and fixing happens in your own browser. Your audio never leaves your device, so an unreleased song, a private interview or a family voice note is never copied anywhere.
What to know before you start:
A journalist evens out an interview recorded half in a cafe and half in a quiet office. A son cuts his father’s favorite chorus into a ringtone as a surprise. A student records a lecture, speeds it to one and a half for revision, and a podcaster joins an intro, an episode and an outro without opening studio software. Sound jobs are small right up to the moment they block something bigger.
Yes. Every tool on this page is free, with no paid plan behind it. ToolPeko earns from ads on the site, not from charging you to download your own audio back.
No. The work runs inside your browser, on your own device. Your songs and recordings never travel to us, and nothing is kept when you close the tab.
On your device, as a file you download. The microphone stream is never sent anywhere. If you do not download it, closing the tab removes it.
No. WAV is a bigger container, not a better copy. The sound stays exactly what the MP3 held. Convert to WAV when a program asks for it, not for quality.
It uses the browser’s own speech recognition, which is strongest in Chrome. Firefox and Safari offer limited support or none. The page will tell you if your browser cannot listen.
Open the Ringtone Maker, drop the song in, and drag the cut to the part you love. Android takes the MP3 as it is. On iPhone, the file is added through the GarageBand or Finder route your phone already uses.
Yes. Converting, cutting and recording all run in the browser on Android and iPhone. Long recordings are calmer on a computer, where there is more memory to work with.
This is only one drawer of the toolbox. The rest work the same way: free, in your browser, with nothing uploaded.
