How to Compress Audio for Discord
- 1Open the audio compressor
Go to our audio compressor. It loads FFmpeg in your browser so nothing gets uploaded.
- 2Upload your audio
Drag and drop your audio file or click to browse. Accepts MP3, WAV, FLAC, AAC, OGG, and M4A files.
- 3Pick a Discord-friendly bitrate
For free accounts (10MB limit): choose 128kbps for music or 64kbps for voice recordings. If the file is still too large, trim it first with the audio trimmer.
- 4Download and upload to Discord
Click Compress, wait for processing, and download the MP3. Drag it into any Discord channel and it plays inline.
Tips for Smaller Discord Audio Files
- 1.Trim first. Remove silence and unnecessary sections with the audio trimmer before compressing. Shorter files compress to smaller sizes.
- 2.Convert WAV/FLAC to MP3. Uncompressed formats are 5-10x larger. Our WAV to MP3 converter handles this automatically.
- 3.Use 128kbps for music. It gives the best balance between size and sound quality for Discord. Most people cannot hear the difference from 320kbps on Discord's audio player.
- 4.Use 64kbps for voice. Podcasts, voice memos, and spoken word sound perfectly clear at 64kbps and produce much smaller files.
Estimated Output Size by Duration
Approximate MP3 file sizes after compression. Original WAV sizes shown for comparison.
| Duration | WAV (original) | 64kbps MP3 | 128kbps MP3 |
|---|---|---|---|
| 30 seconds | ~5 MB | ~0.25 MB | ~0.5 MB |
| 1 minute | ~10 MB | ~0.5 MB | ~1 MB |
| 5 minutes | ~50 MB | ~2.5 MB | ~5 MB |
| 10 minutes | ~100 MB | ~5 MB | ~10 MB |
At 128kbps, you can fit roughly 10 minutes of audio under Discord's 10MB free limit. Trim longer recordings with the audio trimmer first.
Frequently Asked Questions
What is Discord's audio file size limit?
Free Discord users can upload files up to 10MB. Nitro Basic subscribers get 50MB, and Nitro users get 500MB. Most WAV and FLAC files exceed the 10MB free limit and need compression.
What bitrate should I use for Discord audio?
128kbps works well for music shared on Discord. For voice recordings or podcasts, 64kbps is fine. 192kbps is best if you want higher fidelity and have Nitro Basic or Nitro.
Will compressing my audio reduce quality?
Converting to MP3 is lossy compression, but at 128kbps most listeners cannot hear a difference for casual listening on Discord. Use the audio compressor to find the right balance.
Is my audio file uploaded to a server?
No. The compressor runs entirely in your browser using WebAssembly (FFmpeg). Your audio files never leave your device.
What audio formats can I compress?
MP3, WAV, FLAC, AAC, OGG, and M4A. The output is always MP3 format, which Discord plays inline without requiring a download.
How much smaller will my audio file get?
WAV files typically shrink 80-90% when compressed to 128kbps MP3. A 50MB WAV becomes roughly 5MB. FLAC files shrink 60-70%. MP3 files already compressed may shrink 30-50% depending on original bitrate.
