Is OGG higher quality than MP3?

At the same bitrate, Vorbis usually holds up better, especially at 128 kbps and below. But converting MP3 to OGG can't add quality; the OGG can only match the MP3 it came from.

Can I convert an MP3 file to OGG online?

Yes. MP3 to OGG runs on this page without an upload: your browser does the work with FFmpeg, so a slow connection doesn't matter once the converter has loaded.

How can I convert audio files to OGG format?

Drop the file in the box above, keep OGG selected, choose a bitrate and press Convert. WAV, M4A and other audio files work too, not only MP3.

How can I convert multiple MP3 files to OGG in bulk?

Not here: this tool converts one file at a time. For a folder of sounds, Audacity's Macros feature or a short FFmpeg loop on your desktop is faster.

Is the OGG file Vorbis or Opus?

Vorbis. It is the codec game engines and resource packs usually expect inside a .ogg, and it plays in Chrome, Firefox and Edge.

Which bitrate should I pick for game audio?

The MP3's own bitrate or the next one up. In practice 192 kbps covers most music and effects; use 320 kbps only if the MP3 is 320 kbps.

Will my looping track be gapless after the MP3 to OGG step?

Vorbis itself adds no start padding, but silence already in the MP3 stays. Loop it in your engine to check; if it clicks, convert from the WAV master.

Do tags and album art carry over?

Cover art doesn't: only the audio stream is written. Check the title and artist in your player or editor before you ship the file.

Does MP3 to OGG conversion work on a phone or Chromebook?

Yes, in current browsers. Short effects convert easily anywhere; for an hour-long ambient track, a desktop browser has more memory to spare.

MP3 to OGG

Make the .ogg file your engine, mod or bot asks for. MP3 to OGG Vorbis at 128, 192 or 320 kbps, free and unlimited, with nothing uploaded.

Your file is converted in your browser and never uploaded to our servers.

How to convert MP3 to OGG

Start by reading one number off the MP3 in your file manager.

1
Look up the MP3's bitrate
On Windows it is under Properties, Details, Bit rate; on a Mac, under Get Info. Write it down before you pick a setting.
2
Drop the file and match or beat that number
Keep OGG selected and choose 128, 192 or 320 kbps at or above the source. A 192 kbps MP3 gets 192; a 320 kbps track gets 320.
3
Save it into your assets folder
After the MP3 to OGG conversion the name stays and only the extension changes, so boss_theme.mp3 becomes boss_theme.ogg and your sound list still finds it.

Why use this MP3 file to OGG converter

Ogg Vorbis inside, not Opus

The .ogg it writes holds Vorbis audio, the codec most engines and resource packs mean when they ask for OGG. In our own test, a 192 kbps MP3 came out as a valid Ogg Vorbis file, along with WAV and M4A copies.

Three bitrates to choose from

128 kbps for footsteps and UI clicks, 192 kbps by default, 320 kbps for a soundtrack. Sample rate and channel count carry over from the MP3 unchanged.

WAV and M4A from the same box

Switch the output to WAV when an engine re-compresses audio on import, or to M4A for an Apple fallback copy. No second site needed.

Unreleased music stays on your disk

FFmpeg runs as WebAssembly in the browser tab and reads the file locally. A track from a game nobody has announced yet never sits on someone else's server.

OGG, WAV or M4A for your game or web project

All three come out of this page. Sizes are per minute of stereo 44.1 kHz audio, worked out from the bitrate.

	OGG Vorbis	WAV	M4A (AAC)
Size per minute	About 1.44 MB at 192 kbps	About 10.6 MB	About 1.44 MB at 192 kbps
Start of the file	No MP3-style encoder padding	No padding	Encoder priming, like MP3
Quality vs your MP3	Second lossy encode	Exact copy of the decoded MP3	Second lossy encode
Bitrate choice	128, 192 or 320 kbps	None, 16-bit PCM	128, 192 or 320 kbps
Apple devices and Safari	Patchy, depends on version	Plays	Plays
Best for	Music and SFX that ship with the game	Engines that compress on import, editing	Web fallback for Apple browsers

Who needs to convert MP3 to OGG

The common thread is software that prefers an open, royalty-free format for sound.

Indie game developers

Many engines and asset pipelines prefer Ogg Vorbis for music and effects. Turn the MP3 a composer or a stock library sent you into the format your project expects.

RPG Maker projects

RPG Maker's audio folders expect .ogg files for background music and sound effects. Convert each track, then drop it into the matching folder.

Minecraft resource packs

Custom sounds in a resource pack must be Ogg Vorbis files. Replace a music disc or a mob sound with your own MP3 after converting it here.

Game mods

Mods that swap a game's soundtrack usually have to match the format the game shipped with, and that is often .ogg. Keep the original file name if the mod guide says to.

Discord bots and soundboards

Many self-hosted bots play Ogg files from a sounds folder. Convert your meme clips once and every command plays the same file.

Web audio and open-source apps

Chrome, Firefox and Edge play Ogg Vorbis in an audio tag, and Linux desktop sound themes use Ogg files. Pair the .ogg with an M4A copy for Safari visitors.

Why game audio is so often Ogg Vorbis

MP3 encoders add a few milliseconds of padding at the start and end of a file. A player that doesn't trim it leaves a tiny gap or click every time a music loop restarts. Ogg Vorbis records exact sample positions, which is why many engines suggest it for looping tracks. It is also royalty-free, so studios could ship it without licensing questions.

One catch: silence that the MP3 encoder baked into the audio can survive any conversion. Test the loop in your engine, and if it still clicks, convert the original WAV instead. The box accepts other audio files, not only MP3.

Before you turn an MP3 file into OGG for a game

Check the source bitrate so you never pick a lower one for the OGG.
Make positional sound effects mono in an audio editor first, because this tool keeps the channel count.
Use lowercase file names without spaces if the file is going into a Minecraft resource pack.
Trim leading silence in an editor before converting a track you plan to loop.
Use the WAV master instead of the MP3 when you still have it.
Confirm your engine wants Ogg Vorbis rather than Opus; this page writes Vorbis.

Common mistakes when you convert MP3 to OGG

Mistake: Renaming song.mp3 to song.ogg.
Do this instead: The audio inside is still MP3, and an engine expecting Vorbis will reject or misread it. Run it through the converter.
Mistake: Picking 128 kbps for a 320 kbps MP3 to save space.
Do this instead: That stacks a second, harsher loss on top of the first. Use 192 or 320 kbps for music; save 128 for short effects and voice.
Mistake: Choosing 320 kbps for a 128 kbps MP3.
Do this instead: The file gets bigger but no better, since detail the MP3 dropped can't come back. Match the source instead.
Mistake: Shipping a stereo file for a sound that should fade with distance.
Do this instead: Some engines, Minecraft among them, only position mono sounds. Make it mono in an editor, then convert.
Mistake: Feeding an OGG to an engine that compresses every import again.
Do this instead: That is a third lossy encode. Pick WAV output here and let the engine do the only compression.

Privacy, price and limits

Nothing is uploaded

The conversion happens in your tab. The only download is the open-source converter itself, about 9 MB once, which the browser then caches.

Free without a counter

No account, email, watermark or daily cap. Convert one sound effect or a whole soundtrack track by track; nothing is metered.

What it won't do

One file at a time, first audio stream only, and embedded cover art is dropped. It doesn't trim, add loop-point tags or batch a folder; Audacity or desktop FFmpeg handle those.
