Supported files
OGG in. AAC M4R out.
OGGM4R
The fixed profile decodes the first audio stream, removes source structure, and writes a fresh M4R with FFmpeg’s iPod muxer.
How it works
Turn OGG audio into individual M4R downloads
Run the fixed conversion
The browser submits one queued item at a time to the server-side FFmpeg profile.
Save the M4R files
Download every completed, separately named M4R result and test it in the intended destination.
M4R processing facts
Newly encoded audio with no ringtone editing.
AAC is encoded at 160k in a fast-start M4R. Fileverses does not trim audio, assess ringtone suitability, or preserve source tags and chapters.
Convert OGG to M4RAudio-bearing OGG only
Each upload must be a non-empty .ogg file of 100 MB or less that host FFmpeg can read with an audio stream.
One selected stream
Only the first audio stream is mapped; alternate audio streams cannot be selected.
Fixed AAC M4R encode
The output is audio-only AAC at 160k in a fast-start M4R written through the iPod muxer, not a stream copy.
No ringtone maker controls
Video, metadata, and chapters are removed. There are no trim, duration, bitrate, channel, sample-rate, or quality controls.
OGG to M4R FAQ
M4R output, explained
What is in the M4R download?+−
A successful download is an audio-only, fast-start M4R containing newly encoded AAC at 160k from the first source audio stream.
Does this make a ringtone automatically?+−
No. It creates an M4R file but does not trim audio, enforce duration, or guarantee suitability for any device or ringtone workflow.
Can I convert multiple OGG files?+−
Yes. Files may be queued and are submitted sequentially, with an individual download for each successful result.
Which OGG files are accepted?+−
Non-empty .ogg files up to 100 MB that host FFmpeg can read and that contain audio are eligible.
Is the OGG audio copied unchanged?+−
No. The first audio stream is decoded and newly encoded as AAC, so the route is not a stream copy.
Will this recover quality or guarantee a file size?+−
No. Re-encoding cannot recover detail discarded in a prior lossy source, and result size depends on the input.
What happens to tags and chapters?+−
Source metadata and chapters are removed, and no stream-selection or audio-setting controls are provided.
