## How to convert AIFF to AMR

1. **Add your AIFF files.** Drag and drop AIFF files onto the converter, paste them, or click to browse. You can add several at once.
2. **Choose AMR.** AMR is already selected. Open Options if you want to change quality, size or metadata.
3. **Convert.** Click Convert. Files are processed in a secure cloud sandbox and are usually ready in seconds.
4. **Download your AMR.** Download each AMR file, or everything at once as a ZIP.

## Good to know

- AMR uses lossy compression, so files get much smaller. The default quality is visually lossless for most content; lower it under Options for even smaller files.
- We encode at a high-quality bitrate by default. Pick a specific bitrate or sample rate under Options.
- This conversion runs on FFmpeg in an isolated cloud sandbox. Files are encrypted in transit and deleted automatically.
