All 49 tools.
Every tool on AudioSaw runs entirely inside your browser tab. Your file is decoded, processed and re-encoded locally — it is never uploaded to a server, so there is no queue, no size gate behind a signup, and no copy of your audio sitting on someone else's disk. Pick the tool that matches the job; each one has the settings for that job already chosen.
Convert to MP3
MP3 is the format that plays on everything — every phone, every car stereo, every cheap MP3 player, every editing program written in the last thirty years. These convert into it from whatever you started with. All of them are lossy encodes, so work from the highest-quality source you have rather than from something already compressed.
MP4 to MP3
Pull the audio track out of a video file as MP3.
M4A to MP3
iPhone voice memos and Apple audio into universally playable MP3.
WAV to MP3
Compress a DAW bounce or recording to a shareable MP3.
FLAC to MP3
Turn a lossless archive into something a phone or car will play.
AAC to MP3
For players and car stereos that never learned to read AAC.
OGG to MP3
Vorbis audio from Discord, Telegram or game files into MP3.
Opus / WhatsApp voice note to MP3
WhatsApp and Signal voice notes into a format anything will open.
MOV to MP3
Audio out of iPhone and QuickTime recordings.
AIFF to MP3
Logic and GarageBand bounces compressed for sharing.
M4B to MP3
Audiobooks out of Apple’s format and onto anything else.
Other format conversions
Conversions that are not about getting to MP3: uncompressed PCM for editing and burning, lossless FLAC for archiving, Apple-native containers, and fixed-bitrate MP3 presets when you want the decision made for you.
MP3 to WAV
Uncompressed PCM for DAW import, CD burning and samplers.
MP3 to M4A
AAC in an Apple-friendly container for iTunes and CarPlay.
MP3 to AIFF
Apple-native uncompressed audio for Logic and Final Cut.
WAV to FLAC
Lossless compression — same audio, roughly half the size.
FLAC to WAV
Decompress lossless audio for software that will not read FLAC.
WAV at 44.1 kHz, 16-bit
The CD standard, locked in — what most software assumes.
WAV to MP3 at 128 kbps
The small-file setting — right for speech, web and email.
MP3 at 320 kbps
The MP3 quality ceiling, locked in.
Video to audio
Video files are containers — the audio inside is usually AAC, and it can be lifted out without re-encoding the picture. Because everything runs locally, the video itself never leaves your machine, which matters more here than anywhere else on the site.
Cut, trim & arrange
Cutting, joining, trimming and shaping. These change the length or arrangement of a file rather than its format, and they are the ones worth chaining together — cut, then join, then fade.
Audio Cutter
Drag handles on a waveform and keep only the part you want.
Audio Joiner
Concatenate several files into one, in the order you choose.
Ringtone Maker
A 30-second clip from any song, in the format your phone wants.
Change audio speed
Slow a song or speed a podcast without shifting the pitch.
Audio Reverser
Play a file backwards — for effects, or to hear what is buried.
Fade in / fade out
Clean fades on both ends without opening an editor.
Trim silence off the ends
Top and tail a recording, leaving the middle untouched.
Remove silence
Strip dead air out of a podcast, voice memo or voiceover.
Loudness & channels
Loudness and channel-count fixes. Most "this file sounds wrong" problems are one of these: it is too quiet, it is louder than everything around it, it is stuck in one ear, or the sample rate does not match the project it is going into.
Normalize Audio
Bring files to a consistent level so nothing jumps out.
Amplify quiet audio
Make a too-quiet recording usable without driving it into distortion.
Compress an audio file
Get a file under an email, Discord or upload size limit.
Stereo to mono
Fix one-sided recordings and halve the size of voice files.
Mono to stereo
Honest dual-mono for software that insists on two channels.
Change the sample rate
Resample to match a project and stop import warnings.
Clean up & separate
undefined
Vocal remover / karaoke
Remove the vocal from a stereo song, or isolate it, by cancelling the centre.
AI vocal remover / stem splitter
Neural separation into a clean instrumental and acapella, running on your machine.
Remove background noise
Strip hiss, hum and fan noise out of a recording with spectral gating.
EQ & bass booster
Adjust bass, mids and treble, or boost the low end, baked into the file.
Pitch & key changer
Shift the key up or down by semitones without changing the tempo.
Record & tag
undefined
For a specific app or device
Presets for a specific destination. Each of these targets one program or device that is fussy about what it accepts, and applies the exact spec that program wants, so the import works the first time.
Audio for Whisper
16 kHz mono WAV — exactly what Whisper wants, in one click.
Prep audio for transcription
The format each transcription service actually wants.
Podcast prep
Normalize, mono mixdown and MP3 encode in a single pass.
Compress audio for Discord
Fits under the upload limit without you doing the maths.
Audio for CapCut
The format CapCut imports without complaint.
Audio for DaVinci Resolve
The format Resolve always imports, no conform errors.
M4A to WAV for Audacity
Skip the FFmpeg install Audacity keeps asking you for.
WAV for SP-404 / MPC
The exact spec hardware samplers need, or they fail silently.
