- API: `POST /api/v1/jobs` with `"operation": "compress"` and an optional `compression_level` or `target_size` (paid plans).
- Format: [OGG converter](https://www.converterrr.com/ogg-converter), [Compress audio files](https://www.converterrr.com/compress-audio).

## What compression does to OGG

Re-encodes at a lower bitrate.

- **Light:** A high bitrate: indistinguishable from the original for most listeners.
- **Balanced (default):** The default: a moderate bitrate that's fine for everyday listening.
- **Strong:** Lowest bitrate: smallest file, best kept for speech and podcasts.

Need it much smaller? Opus sounds as good at a lower bitrate, especially for speech. [Convert OGG to Opus](https://www.converterrr.com/ogg-to-opus).

## How to compress OGG

1. **Add your OGG files.** Drag and drop OGG files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Pick a level or a target.** Balanced is selected and suits most files. Choose Light to stay closer to the original or Strong for the smallest file, or set a target size or a percentage to reduce by.
3. **Compress.** Click Compress. Your OGG files are processed right in your browser, usually in seconds.
4. **Download.** Download each smaller OGG, or everything at once as a ZIP.

## Good to know

- Ogg Vorbis is an open, royalty-free codec, common in games and on Linux. Compressing re-encodes at a lower bitrate.
- Vorbis holds up well at moderate bitrates. For speech-only audio, Opus is smaller still.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the track is compressed to fit.
- OGG compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.

## Compressing OGG: frequently asked questions

### How do I compress an OGG file?

Drop the OGG onto the compressor above, keep Balanced or pick another level, and click Compress. Download the smaller OGG when it's done; it usually takes a few seconds.

### Does compressing OGG reduce quality?

A little, by design: OGG is a lossy format. Balanced is tuned to look the same for most uses; choose Light if you want to stay closer to the original.

### How much smaller will my OGG get?

Vorbis files encoded at high quality shrink considerably; lower-quality files have less headroom.

### Can I compress OGG to a specific size?

Yes. Set a target size in the compressor, or a percentage to reduce by, and the file is compressed to land at or just under it.

### Is it safe to compress OGG files here?

Yes. OGG files are compressed inside your browser with WebAssembly and never uploaded to a server.

### Is the OGG compressor free?

Yes. Compression is free with no watermark and no sign-up, within the same daily allowance as conversions.

### Should I convert my OGG instead?

Sometimes. Opus sounds as good at a lower bitrate, especially for speech. The OGG to Opus converter does that in one step.
