The Encoder / Decoder converts WAV audio files to MP3 or OGG directly in your browser. It supports batch
queues, format-specific quality controls, progress feedback, and local downloads without requiring a server-side
upload for the conversion work.
The converter uses a batch workflow: select files, choose the output format, pick a quality setting, then
export each converted file from the generated download list.

Quick start
How to convert files
Open the Encoder / Decoder tool.
Drag WAV files into the upload area, or click Browse Files.
Confirm the files appear in the batch queue with the correct names, file types, and sizes.
Select MP3 or OGG in Output Format.
Use the Bitrate / Quality slider to choose the export quality.
Click Convert Files and wait for Conversion Progress to reach 100%.
Download each converted file from the download list below the button.

Batch queue
Review selected files before converting
Every uploaded WAV file is added to the batch queue. The queue is designed for checking the source filename,
file type, and file size before starting conversion. Use Clear All to reset the queue if you
selected the wrong files.
Batch conversion is local to the browser. Converting many long files at once can use significant CPU and
memory, so smaller batches are more reliable on low-power devices.

Output settings
Choose MP3 or OGG
The Output Format dropdown changes how the quality slider behaves. MP3 uses fixed bitrate steps measured in
kbps. OGG uses Vorbis quality values, which are shown as quality levels with approximate bitrate equivalents.

320 kbps
Highest standard MP3 bitrate; common for downloads.
MP3 bitrate guide
MP3 is the safest choice when you need maximum playback compatibility across phones, browsers, media players,
cars, and older hardware.
128 kbpsSmall files, acceptable for voice notes, drafts, and speech-heavy audio.
192 kbpsBalanced size and quality for casual music sharing.
256 kbpsHigh-quality music export with less compression loss.
320 kbpsHighest standard MP3 bitrate; best for downloads and archiving in MP3.
OGG quality guide
OGG Vorbis can produce efficient files at similar perceived quality, but compatibility is not as universal as
MP3 on older devices.
q0 (~64 kbps)Low quality, useful for speech and very small files.
q2 (~96 kbps)Basic music quality with compact output.
q4 (~128 kbps)Standard quality for general-purpose audio.
q5 (~160 kbps)Recommended quality for most music exports.
q6 (~192 kbps)High quality with efficient file size.
q8 (~256 kbps)Very high quality for demanding listening.
q10 (~500 kbps)Maximum quality, larger files.
Conversion and downloads
Track progress and save the results
The Conversion Progress meter reflects the batch conversion process. When conversion finishes, download links
appear below the Convert Files button. If many files are converted, that download area scrolls so every result
remains reachable.
The tool decodes and encodes audio in the browser using client-side JavaScript and WebAssembly-based audio
tooling. The conversion pipeline avoids a server-side conversion queue, which keeps the workflow fast for
short and medium files and lets users download results immediately after encoding.
Input: WAV files selected by the user.
Outputs: MP3 or OGG, depending on the selected format.
Batch behavior: each file is converted and then exposed as an individual download link.
