HOW IT WORKS
1
Drop the ogg file
Drag your OGG onto the page or click to browse. It is read locally, never sent anywhere.
2
Choose AAC and bitrate
Pick 128, 192, 256 or 320 kbps. 192 kbps is the default. Click Convert to start processing in this tab.
3
Save the aac
The finished AAC downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Your ogg file is decoded and re-encoded by code in this tab - a song, a memo, a podcast never leaves the device.
Local conversion
No upload time for a big ogg file, no server queue, no waiting on a download link.
No account, no daily cap
No daily caps, no "3 conversions left", no email wall. Convert the whole ogg library.
The two formats, briefly
| OGG | OGG is a container. This converter writes Vorbis audio at a fixed quality setting, not Opus. | |
|---|---|---|
| AAC | AAC is a lossy audio codec. This page writes a standalone AAC file using the selected bitrate. | |
When you need this
- Use AAC when your receiving app or player does not accept OGG. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
OGG vs AAC: what changes
| OGG | AAC | |

Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
OGG to AAC, answered
Why convert OGG to AAC?+
Use AAC when your receiving app or player does not accept OGG. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
Which quality should I pick?+
The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
Does converting OGG to AAC lose quality?+
This export uses lossy audio encoding. The source OGG may contain different codecs or recording quality; re-encoding cannot improve the original. Compare the result before deleting the source.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
No. The file is read and converted by code running in this browser tab. Your file is never sent to a server - its contents stay in this tab.
