Quick tips
- Desktop browsers are better for larger files than phones.
- Drag and drop is supported by the tool UI.
- Keep originals when processing very large WAV or FLAC files.
How to use
- Use a modern desktop browser on Windows, macOS, or Linux.
- Drag a file into the tool or choose it from disk.
- For large WAV or FLAC files, export a smaller MP3 or AAC copy and keep the original.
- Wait for the browser to finish encoding before closing the tab, especially with long recordings.
Recommended settings
| PC workflow | Suggested setting |
|---|---|
| Large WAV recording | MP3/AAC, 96-192 kbps |
| Podcast editing export | MP3, 96-128 kbps |
| Music demo | MP3, 160-192 kbps |
| Archive source | Keep original, export copy |
| Many files | Use batch compressor |
Supported formats
Desktop browsers are practical for MP3, WAV, M4A, AAC, OGG, and FLAC inputs through ffmpeg.wasm.
Use MP3 for broad sharing, AAC for efficient playback, and OGG for web or game assets.
Quality vs file size
A PC usually has more memory and CPU headroom than a phone, so larger local compression jobs are more realistic.
File size still depends on duration, bitrate, sample rate, channels, and output format. The device only affects processing speed.
Privacy and local processing
Compression runs in your browser, so the original audio is not uploaded to a server.
Large files can still be slow because decoding and encoding use your device memory and CPU.
Things to watch
- Very large files can still take time in the browser.
- Do not close the tab while encoding is running.
