Where these formats come from
MP3 came out of years of research at Fraunhofer and was standardised in 1993 as part of MPEG-1. Its trick is psychoacoustic: it throws away the sound a human ear is unlikely to notice, mostly quiet detail masked by louder sound nearby, and it was that trick which made music small enough to travel over a modem. AAC — the thing inside an .m4a file — was designed as its successor and does the same job better at the same size. Ogg Vorbis appeared in 2000 as the patent-free answer, at a time when MP3 still had to be licensed. FLAC compresses without discarding anything, giving back the identical recording at about half the size, and WAV stores the raw samples with no compression at all.
Where you meet them
MP3 is still the format that plays on anything with a speaker, which is why it is the safe choice for sending something to a stranger. M4A is what Apple devices and most phones record and buy in. OGG travels inside games and open-source software. FLAC is for archiving a collection or ripping a CD when the original quality must be kept. WAV is the working format of recording and editing, where the file is opened and saved repeatedly and compression artefacts would accumulate.
Questions people ask
Will converting my MP3 to FLAC restore the quality?
No. FLAC will preserve perfectly whatever it is given, but what it is given here is already an MP3 — the detail removed when the MP3 was made is gone, and no later format can invent it back. You end up with a file several times larger that sounds exactly like the MP3. Converting to a lossless format is worth doing only from a lossless source; from an MP3, the honest answer is to keep the MP3.
Each time I convert, does it sound worse?
Between lossy formats, yes — a little. MP3, AAC and Vorbis each decide separately what the ear will not miss, and each conversion decodes the previous guess and makes a fresh one on top of it, so the losses accumulate. Converting once rarely matters; converting back and forth repeatedly does. Lossless formats have no such problem: WAV to FLAC to WAV returns exactly the samples you started with.
Does the file lose quality?
It depends on what the two formats can hold. Converting between formats that store the same thing — a PNG to a BMP, a WAV to a FLAC — loses nothing. Converting into a format that throws information away to save space, such as JPEG or MP3, loses a little every time, and converting back does not bring it back. Where a choice exists, this page errs towards keeping the original quality rather than making the smallest file.
Is my file uploaded anywhere?
No. The conversion happens inside your browser, on your own machine; the file never leaves it and there is no server here that could receive it. That is why a large file is limited by your own memory rather than by an upload, and why nothing you convert can appear in anybody's logs — including ours. The audio and video tools do fetch their conversion engine from this site the first time you use them, some thirty megabytes once; after that the work still happens entirely on your machine.
Why people convert OGG to MP3
OGG is the open audio format: free of licences, loved by open-source software, games and some streaming services, and well supported on Linux and in many apps. But step outside that world and it can be awkward. A car stereo that will not read it. An older phone or portable player that skips it. A music program that does not list it. An upload form that accepts only MP3. MP3, by contrast, is the format that plays on everything made in the past twenty-five years. That is why people convert OGG to MP3: they have a recording in a format that works in some places, and they need one that works everywhere.
The situations are ordinary. A game soundtrack ripped from a game's files, to play on a phone. A recording made with open-source software, to send to someone who uses a commercial player. A song downloaded as OGG that a car stereo refuses. A voice message exported as OGG that a colleague cannot open. In every case the sound is fine and the container is the problem, and converting OGG to MP3 solves it in moments.
This page converts OGG to MP3 in your browser. Your recording is not uploaded to a server, so there is nothing to delete afterwards, which matters for private recordings and unreleased work. Below you will find how the conversion works, what is kept, what honestly costs you something and when it is worth doing.
How the conversion works
Decoded here, written as MP3 at the bitrate you pick
Your OGG is decoded in your browser, which means it is turned back into raw sound, and then written out as an MP3 at the bitrate you choose. The bitrate decides how many bits are used for each second of sound: a lower number gives a smaller, rougher file; a higher number gives a larger, cleaner one. You can pick the balance that suits the recording and where it is going.
Nothing is uploaded
The whole process happens on your own device, so your recording never leaves it. There is no copy on a server and nobody else who could hear it. For a private conversation or unreleased music, that is the right way to convert OGG to MP3.
Choosing a bitrate
For speech, 96 or 128 kilobits per second is plenty and keeps the file small. For music, 192 or more gives a good result. Because OGG is already compressed, choosing a bitrate above its own gains nothing, so do not pick a higher number than the original in the hope of better sound.
What is kept
The full length and the sample rate
When you convert OGG to MP3 here, the full length of the recording is kept, and so is its sample rate, which is how finely the sound was sampled. A song of four minutes stays four minutes. Nothing is cut or sped up.
Both channels, mixed down properly if there are more
Both channels of a stereo recording are kept. If the file has more than two channels, it is mixed down properly into stereo, so nothing in the middle goes missing. That matters for game audio and film sound, where a centre channel carries dialogue, and a careless conversion would lose it.
What "mixed down properly" means
An OGG can hold more channels than a standard MP3 can. A careless conversion would drop the extra channels, and any voices placed in the centre would vanish. Here the extra channels are blended into the left and right, so every sound is still there.
Opens anywhere
The MP3 you get opens on practically any device and in any program. That universality is the reason you made the conversion in the first place.
What honestly costs you something
A second round of loss
Both OGG and MP3 are lossy formats: each discards some of the sound to keep files small. When you convert OGG to MP3, you apply that discarding a second time, on top of the first. The result is a little worse than the OGG was, at any bitrate. For speech and ordinary listening the difference is small, often impossible to hear. But it is real, and it does not go away.
Worth doing when something cannot read OGG
That is why the conversion is worth doing when something cannot read OGG, and not otherwise. If your player, your car or your program can play OGG, leave the file as it is: you would pay a loss of quality for no benefit.
Titles, artist names and cover art are not carried over
Only the sound itself is read. Titles, artist names and cover art stored in the OGG are not carried over, so the MP3 appears under its file name without tags. For a game soundtrack or a voice message, that rarely matters; for a music collection, you will need to add the tags again in a tag editor.
Keeping music organised
If you convert songs, name the MP3s clearly, for example with the artist and title in the file name, so that they are identifiable without tags. A music manager can read the names and fill in the tags for you, which saves a lot of typing.
What OGG and MP3 are
OGG is a container for audio, usually holding sound compressed with a method called Vorbis. It was created as a free alternative to patented formats, with a published specification that anyone may use, which is why it is popular with open-source projects, game developers and some online services. At a given bitrate, Vorbis often sounds a little cleaner than the method MP3 uses, so an OGG tends to give the same quality in a slightly smaller file. MP3 is older, but it became the universal language of digital audio, and virtually every device can play it.
That trade explains what you will see when you convert OGG to MP3. If you choose a bitrate similar to the original, the MP3 will be a similar size with a slightly lower quality. If you choose a lower one, it will be smaller still, and the loss more noticeable. The right choice depends on what the recording is and where it will be played.
Why open formats still meet closed equipment
OGG is an open standard, but equipment makers decide what their devices play, and many have never added it. Cars, cheap players, older phones and some smart speakers read MP3 and little else. That gap between an open format and the hardware people own is why converting OGG to MP3 remains such a common need.
Game audio and open-source recordings
A great deal of OGG audio comes from games: music, sound effects and voice lines are stored as OGG in many game files. Fans who extract soundtracks to listen to them elsewhere find the files will not play on every device. Open-source recorders, voice-chat tools and podcast software also tend to write OGG. When you convert OGG to MP3, those sounds become playable on any phone, any computer and any stereo.
If you are working with game files, remember that soundtracks and sound effects may belong to the game's creators. Convert files you have the right to use, for personal listening or for material you own, and respect the licence of anything you share.
Short sound effects
Very short sounds, a second or two, convert in an instant. If you have a folder of effects, convert them in a batch and name the files clearly. For short effects, a higher bitrate costs almost nothing in size, so choose 192 or more and avoid any audible roughness.
Voice messages and field recordings
Some messaging apps and voice recorders save voice notes as OGG. If you need to send one to someone whose device cannot open it, converting OGG to MP3 is the simplest fix. For speech, 96 or 128 kilobits per second is plenty, and the resulting file is small enough for email or a messaging attachment. Field recordings, such as a bird song or an interview, behave the same way.
For important recordings, such as an interview or a meeting, keep the OGG as the original and treat the MP3 as the copy you share. If someone later needs a different format or a better quality, you can convert again from the original, rather than from a lossy copy.
Cleaning up noise first
If a recording is noisy, with hiss or hum, it is better to clean it before you convert. Each lossy conversion makes noise slightly harder to remove afterwards. Do the cleaning in the original format, then convert OGG to MP3 as the last step.
How to convert OGG to MP3 here
Add your recording
Drop the OGG onto the page or pick it from your device. It is read inside your browser and is not uploaded.
Pick a bitrate
Choose a bitrate that suits the content: lower for speech, higher for music. If you are not sure, a middle setting is a safe choice.
Convert and listen
Press the button and download the MP3. Listen to the beginning, a stretch from the middle and the end. If it sounds fine on the device where it will be played, you are done.
Questions people ask before converting
Will the sound get worse?
Slightly. Both formats are lossy, so this is a second round of loss. For speech it is rarely noticeable. Keep the OGG if it is your only copy.
Why are the titles missing?
Only the sound is read. Titles, artist names and cover art are not carried over. Add them again with a tag editor if needed.
What happens to a surround recording?
It is mixed down properly into stereo, so nothing in the middle goes missing.
Is my recording uploaded?
No. Everything runs in your browser and the recording never leaves your device.
Who converts OGG to MP3
Users of open-source software and games
Audio from games and open-source tools is often OGG. Converting makes it playable on any phone or car stereo.
People sharing voice messages and recordings
A colleague with a different system can open an MP3 without trouble.
Owners of older players
Many older players and stereos read only MP3. Converting gets your music onto them.
Common mistakes
Converting when you do not need to
If your equipment plays OGG, leave it. The conversion costs a little quality for no benefit.
Deleting the original
Keep the OGG if it is your only copy. You cannot get the lost detail back.
Choosing a bitrate higher than the original
It does not improve the sound and only makes the file bigger.
Related tools
To go the other way, convert MP3 to OGG. For other audio formats, M4A to MP3, WAV to MP3 and FLAC to MP3 work the same way, and MP3 to WAV, MP3 to M4A and MP3 to FLAC cover other destinations. If the audio belongs to a video, FLV to AVI and AVI to FLV change the video container.
When to convert OGG to MP3, and when not to
Converting is right when the recording has to be played by something that does not read OGG: an older phone, a car stereo, a player, a program or a person with different equipment. It is the wrong move when everything you use plays OGG, since you would only lose a little quality, and wrong when the recording is a master you will edit or archive, where the original is the better file.
For the common cases, such as game music, voice messages and recordings for older equipment, it is quick, private and dependable to convert OGG to MP3 in the browser. Your original is never changed, so you can come back and convert OGG to MP3 again at a different bitrate whenever you like.
Do not convert in circles
Avoid chains such as OGG to MP3 to OGG to MP3. Each pass through a lossy format costs a little more, and after three or four the sound becomes noticeably rough. If you need several formats, make each from the original, not from a copy of a copy.
Batches of recordings
If you have many recordings to convert, do them one at a time and keep the originals in a separate folder. Try one first and listen to it on the device where it will be played. When you convert OGG to MP3 in bulk, consistency matters more than speed.
Long recordings and slow devices
Everything runs on your own device, so very long recordings depend on its memory. An hour of audio is no trouble for a modern phone or computer. A very long recording may be slow on an older device. If it struggles, give the browser a moment and avoid switching to other apps while it works.
Checking the result properly
After you convert OGG to MP3, listen to the beginning, a stretch from the middle and the end, on the equipment that matters. Check that the length is right and that nothing has been cut off. If it sounds good there, you are done; if it sounds rough, convert again from the original at a higher bitrate.
A simple routine to convert OGG to MP3 well
Decide where the recording is going and whether it really needs MP3. Keep the OGG safe. Convert OGG to MP3 once, from the original, at a bitrate suited to the content: lower for speech, higher for music. Listen to the result on the target device, then use it and keep the original. This routine takes a couple of minutes, and it works whether you convert OGG to MP3 once a month or every day.
Your recording stays on your device
The conversion happens locally. Your recording is decoded by your own browser, written as an MP3 there and handed back. Nothing is uploaded, so there is no copy on a server and no one else who could hear it. For private recordings and unreleased work, that is the safe way to convert OGG to MP3.
A worked example
Say you have a soundtrack ripped from a game as OGG files, and you want to hear it in your car, whose stereo reads only MP3. You drop a track here, choose 192 kilobits per second and press the button. You download an MP3 of the same length, which sounds just as you remember it. You convert the rest of the album the same way, name the files by track number and copy them to a USB stick. The OGG originals stay on your computer.
Before you close the page
Check that you downloaded the MP3, that it sounds fine on the device where it will be played, and that you kept the original OGG.
Summary
To convert OGG to MP3 here, drop the recording, pick a bitrate and download the result. The full length, the sample rate and both channels are kept, and a file with more than two is mixed down properly. Both formats are lossy, so this is a second round of loss and the MP3 is a little worse than the OGG was. It is worth doing when something cannot read OGG, and not otherwise. Titles, artist names and cover art are not carried over. Nothing leaves your device.
