What do you want to do?

Cut & Trim

Shorten a song, keep only the best part, or make a ringtone — select the range on the waveform and save it.

Merge & Convert

Join tracks into one file, pull the audio out of any video, and switch between MP3, WAV, M4A, OGG and more.

Record

Capture your microphone straight in the browser — trim the take and save it as MP3, nothing leaves your device.

Effects & Studio

Boost volume, change speed or pitch, add reverb and fades, EQ the lows and highs — and visualize sound as a waveform or spectrogram.

MP3 Editor

One tab for quick edits: trim, fade, reverse, speed up and normalize any track.

Reverse Audio

Play a track backwards to make effects, check a mix or just for fun.

Audio Speed Changer

Speed up lectures to 2× or slow down riffs to learn them — pitch stays true.

MP3 Volume Booster

Lift quiet voice memos up to 4× with a limiter so nothing clips.

Volume Booster

Make quiet music and video soundtracks loud and clean, up to 4×.

Audio Normalizer

Bring a whole batch of recordings to one consistent, healthy level.

Level Compressor

Pull loud peaks down and lift quiet words, without making the whole file louder.

Echo

Add spaced repeats you can time — a slap, a canyon, not a wash of reverb.

Silence Remover

Cut the long quiet stretches and leave the short breaths where they are.

Loudness Meter

Read how loud a file is in LUFS, then match a podcast, streaming, or broadcast target.

Slowed + Reverb

Give any track the late-night slowed + reverb treatment in one click.

Treble Booster

Add sparkle and clarity by lifting the highs up to +15 dB above 3 kHz.

Audio Equalizer

Shape low, mid and high shelves with a straightforward three-knob ±15 dB EQ.

Low Pass Filter

Keep only the warmth below the cutoff — great for lo-fi textures and mutes.

High Pass Filter

Strip rumble and hum below the cutoff for cleaner voice recordings.

Waveform Generator

Turn any track into a shareable waveform picture with your own colors.

Spectrogram Generator

See the frequencies inside a song, a recording or a bird call.

Image to Audio

Hide a picture or a line of text inside a WAV spectrogram.

Bass Booster

Add weight and punch with up to +15 dB of low shelf below 150 Hz.

Audio Fade In / Fade Out

Smooth song endings and podcast intros with exact fade in/out times.

Pitch Changer

Shift a song up or down in semitones for covers and mashups — same length.
