Convert OGG to MP3 — Free & Private
Turn OGG, OGA and OPUS files into MP3s that play on anything: WhatsApp and Telegram voice notes, game music, Audacity exports, Wikimedia recordings. Drop them below. They're converted on your own device, several at once, with title, artist and cover art carried over.
OGG to MP3, in short: drop the files above, press Convert, download the MP3s. Nothing is sent anywhere. The conversion runs in this browser tab.
- How do I convert OGG to MP3 for free?
- Drop the .ogg, .oga or .opus files in the box above and press Convert to MP3. Each file gets its own Download button. With two or more, a single ZIP is offered too.
- Can I convert a WhatsApp or Telegram voice note?
- Yes. WhatsApp saves voice notes as .opus files and Telegram as .ogg or .oga. All three are Opus audio in an Ogg container, and this tool reads them directly.
- Does it keep the song title and cover art?
- Yes. Title, artist, album, track number, year, genre and embedded cover art are read from the OGG file and written into the MP3 as ID3 tags.
- What MP3 bitrate should I pick?
- Leave it on Auto. It measures the OGG's real bitrate and picks an MP3 bitrate a step above it, because MP3 needs more bits than Vorbis or Opus for the same sound. Mono voice notes stay mono.
- Is there a file size limit?
- Up to 200 MB per file and 50 files at a time. There is no daily limit and no sign-up.
- Can I trim, fade or change the volume while converting?
- Yes. Open More options to set start and end times, fade in and out, change the volume or normalize it, switch to mono, change the sample rate, reverse the audio or reduce centre vocals.
- Are my files uploaded?
- No. The audio is decoded and encoded on your device. The page downloads its encoder the first time it needs it, then your files never leave the browser.
WhatsApp and Telegram voice notes to MP3
A voice note is the most common OGG file most people ever meet, and it's rarely named .ogg. WhatsApp on Android keeps them as PTT-20260924-WA0001.opus in its Voice Notes folder. Telegram hands out .ogg or .oga. Inside, all three are the same thing: Opus audio in an Ogg container.
Many places that need an MP3 won't take them: an older iPhone, a car stereo, a transcription service, an email to someone on an old PC. Drop them in as they are. You don't need to rename anything, because the tool checks the file's first bytes, not its name.
- Mono stays mono. A voice note is one channel. Doubling it to stereo would double the size and add nothing.
- Small stays small. Voice notes are recorded at a low bitrate. Auto encodes a low-bitrate mono note at 64 kbps, about 480 KB a minute.
- Many at once. Select a whole batch of notes and download them as one ZIP.
What "Auto" quality picks, and why it goes up
Vorbis and Opus are more efficient than MP3, so a 128 kbps OGG usually sounds better than a 128 kbps MP3. Converting at the same number loses a little more quality. Auto reads the file's real bitrate (its size divided by its length, not counting cover art) and chooses:
| OGG bitrate | Stereo MP3 | Mono MP3 |
|---|---|---|
| up to 40 kbps | 128 kbps | 64 kbps |
| 41–72 kbps | 128 kbps | 96 kbps |
| 73–96 kbps | 128 kbps | 128 kbps |
| 97–128 kbps | 160 kbps | 128 kbps |
| 129–160 kbps | 192 kbps | 128 kbps |
| 161–200 kbps | 256 kbps | 128 kbps |
| over 200 kbps | 320 kbps | 128 kbps |
Pick a fixed bitrate from 64 to 320 kbps if you need a particular number, for example a podcast host that asks for 128 kbps. Or pick VBR, which spends more bits where the music is busy and fewer where it's quiet. Converting can't restore detail the OGG never had: a higher MP3 bitrate only avoids losing more.

How to Convert OGG to MP3
- Add the files. Drop them in the box at the top, or press Browse. .ogg, .oga and .opus all work.
- Leave quality on Auto, or pick a bitrate or VBR. More options adds trim, fades, volume, mono and sample rate.
- Press Convert to MP3. Each file shows its progress, and short clips take a second or two.
- Download. Each file gets its own button, and there's a ZIP when you've converted two or more.
Where OGG plays, and where it doesn't
Chrome, Firefox, Edge, Android, VLC, Linux players, Unity and Godot. Safari on iOS 18.4, iPadOS 18.4 and macOS 15.4 or later.
iPhones before iOS 18.4. The Apple Music app library. Windows Media Player without Web Media Extensions. Many car stereos and older MP3 players.
Practically every phone, computer, car stereo, player and app made in the last 25 years.
SoundCloud accepts Ogg Vorbis as it is. YouTube takes no audio-only files, so it needs a video either way. Try MP3 to MP4.
Key Questions About OGG to MP3, Answered
Straight answers to the questions people actually ask about this conversion.
Does converting OGG to MP3 make the audio worse?
Technically yes, but usually not in a way you'll hear. The OGG file is already lossy, so converting to MP3 means decoding the Vorbis audio and running it through MP3's encoder — a second compression pass that discards a little more data. At matched or higher bitrates this extra loss is hard to detect by ear. The reason to convert isn't to improve the sound; it's that MP3 plays everywhere OGG doesn't.
- OGG already discarded data during its original Vorbis encoding
- MP3 re-encoding adds a second, usually minor, layer of loss
- At 192kbps and above, the difference is rarely noticeable
- Avoid converting a low-bitrate OGG down to an even lower MP3 bitrate
What MP3 bitrate matches my OGG file's quality?
Because Vorbis is somewhat more efficient than MP3 at the same bitrate, it's worth going slightly higher when converting to MP3 to avoid a perceived quality drop. A Vorbis quality 3–4 file (roughly 112–128kbps) converts well to 160kbps MP3. Quality 5–6 (roughly 160–192kbps) maps to around 192–224kbps MP3. Quality 7–8 (roughly 224–256kbps) maps to 256–320kbps MP3. If in doubt, 256kbps MP3 is a safe general choice that won't introduce a noticeable downgrade.
- Vorbis q3–q4 (~112–128kbps) → 160kbps MP3
- Vorbis q5–q6 (~160–192kbps) → 192–224kbps MP3
- Vorbis q7–q8 (~224–256kbps) → 256–320kbps MP3
- When unsure, 256kbps MP3 is a safe default that avoids a quality step-down
Why convert OGG to MP3 if the codec is technically worse?
Pure device reach. MP3 has been built into every car stereo, portable player, DJ controller, smart TV, and media app made in the last 25 years, while OGG support is inconsistent outside Linux, Android, and certain games. If you've got audio exported from a game engine or open-source app and need to play it in a car, on an old iPod, or in software that simply doesn't list OGG as a supported format, MP3 is the fallback that's guaranteed to work.
- MP3: supported by virtually every audio device and app ever made
- OGG: solid on Linux/Android/games, but inconsistent elsewhere
- Convert when your playback device or software doesn't recognize .ogg
- Keep the original OGG file for use on platforms that do support it
Will the MP3 sound noticeably different from the OGG on normal speakers or earbuds?
For most people, no. Both Vorbis and MP3 are tuned to sound transparent at moderate-to-high bitrates on typical playback equipment. The differences between the two codecs mainly show up in critical listening tests on high-end headphones, not on phone speakers, car audio, or earbuds. The practical result of converting is broader compatibility, not a perceptible change in how the music sounds during normal listening.
- At 192kbps+, both formats sound clean on typical playback gear
- Codec differences are mainly audible in critical listening tests, not casual use
- The main benefit of converting to MP3 is where it plays, not how it sounds
- Use headphones and a quiet room if you want to compare critically
