Convert audio files in your browser
Studio recordings, voice memos, ripped CDs and podcast masters, moved between the lossless formats that editors want and the compressed ones that phones, players and email attachments want.
The pages in this section are specific about what each conversion does to the sound: which bitrate we pick by default and why, when a lossless copy of a lossy file is pointless, and how much space a change saves or costs. Trim is available on every audio conversion.
Nothing is uploaded. Your browser reads the file, encodes it on your own machine and saves the result where you choose. A three-minute track converts in a few seconds on a laptop.
Runs in your browser. Your file never leaves your computer.
31 audio conversions
- WAV to MP3Turn a large studio recording into a small file that plays anywhere, at a bitrate where almost nobody can hear the difference.
- MP3 to WAVFor the DAW, the sampler, the CD burner or the hardware that refuses compressed audio. Uncompressed 16-bit PCM, nothing added, nothing recovered.
- WAV to FLACFLAC keeps every sample of the recording and still cuts the file roughly in half. The archive format for audio you may need again.
- FLAC to WAVUncompressed PCM for the editor, burner or instrument that refuses FLAC. Same sound, bigger file, zero decoding surprises.
- WAV to M4AAAC at 256 kbps: better sound per megabyte than MP3, native on every Apple device, fine everywhere else.
- M4A to WAVPlain PCM out of an AAC file, for the tool in your chain that wants WAV and nothing else.
- WAV to OGGThe most efficient codec in wide use: transparent around 128 kbps, ideal for the web and for apps, weaker on Apple hardware.
- OGG to WAVOpus and Vorbis files, decoded to plain PCM for editors, burners and anything that never learned OGG.
- AIFF to FLACApple's uncompressed studio format packed losslessly to about half the size, with tags that actually work.
- AIFF to M4AFrom a studio-size file to a share-size one: AAC at 256 kbps, native on the Apple gear the AIFF came from.
- AIFF to MP3The universally playable delivery format, encoded from your uncompressed audio on your own machine.
- AIFF to OGGThe efficiency codec for web and app work, straight from uncompressed source, no server in the loop.
- AIFF to WAVSame uncompressed audio, different wrappers. When a tool insists on WAV, this swaps the wrapper without touching a sample.
- FLAC to M4AYour lossless library, made playable on iPhones and everything else, at 256 kbps AAC.
- M4A to FLACOnly for one honest reason: a workflow that wants lossless input files. No quality returns; the page is upfront about that.
- FLAC to MP3From archive copy to everyday copy: 320 kbps MP3 encoded from lossless source, the best MP3 can be.
- MP3 to FLACNot the sound. What it offers is lossless preservation of what the MP3 is now, for workflows that ask for FLAC.
- FLAC to OGGOpus from lossless source: transparent files small enough for a phone full of albums, if your players cooperate.
- OGG to FLACGame audio and open-format downloads, decoded once and stored losslessly for tools that want FLAC.
- M4A to MP3Old car stereos, ancient players, strict systems: the one format they all know, made from your M4A locally.
- MP3 to M4AWhen a workflow or app insists on M4A. Honest note: this cannot make the MP3 sound better, only fit better.
- M4A to OGGFor open-format targets: game engines, web projects and Linux setups that prefer OGG containers.
- OGG to M4AThe Apple-native container for audio that arrived in an open one. Converted in your browser, generation loss disclosed.
- MP3 to OGGFor OGG-only pipelines. Stated upfront: from MP3 source, this trades a little quality for a lot of compatibility.
- OGG to MP3Downloads and game audio in open containers, moved to the format that every device on earth accepts.
- Audio equalizerA six-band EQ you play with: drag the curve, hear the change live, A/B against the original, then save as WAV or a smaller format. The file stays on your computer.
- Bass boosterA clean low-shelf lift below 90 Hz with a limiter guarding the peaks: fuller low end, no clipping. Starts gentle at +3 dB; drag the curve for more. Works on MP3, WAV, FLAC, M4A and OGG.
- Audio limiterA lookahead limiter, live in your browser: add up to 24 dB of gain while every peak stops at the ceiling you set. In plain words — a volume booster that can't distort. Nothing is uploaded.
- Normalize audioIt measures how loud the file really is — the LUFS number streaming services use — and raises or lowers it to a standard target. Every file you run through it comes out at the same level.
- Audio compressorA full compressor with live preview: threshold, ratio, attack, release, knee, makeup and a delta mode that plays exactly what is being changed. Processed privately in your browser.
- Stereo widenerPushes the sides of a stereo mix outward so it sounds bigger on headphones and speakers, while bass below 120 Hz stays anchored in the middle. Runs on your machine; saves as WAV or smaller.
