Free Audio Compressor Online — Reduce MP3 and AAC File Size
Reduce audio file size by adjusting the bitrate. Compress MP3, AAC, OGG, WAV and FLAC files online without software. Choose the right bitrate for music, podcasts or voice.
Bitrate guide: choose the right setting
320 kbps: maximum quality — audiophile standard, no perceptible difference from lossless. Best for final masters and archiving. 192 kbps: high quality — most listeners cannot distinguish this from 320 kbps. Recommended for music streaming and distribution. 128 kbps: good quality — clearly audible difference to trained ears but acceptable for most listeners. Recommended for podcasts, voice recordings and background music. 96 kbps: acceptable for voice-only content (podcasts, audiobooks, interviews). Noticeably compressed for music. 64 kbps: low quality, very small file — suitable for voice memos and low-bandwidth applications only.
Lossless vs lossy compression: what you need to know
Audio compression is lossy — once data is removed at a lower bitrate, it cannot be recovered. Always keep your original high-quality file before compressing. The compressed output is suitable for sharing, streaming and distribution, but not as a source for future production work. For lossless compression (smaller file with no quality loss), use FLAC format — it reduces file size by 30-50% without any data removal.
FAQ
Is audio compression destructive?
Yes. Reducing bitrate below the original permanently removes audio data. Always keep your original file. Compression is irreversible.
What bitrate should I use for a podcast?
128 kbps for stereo podcasts. 96 kbps for mono voice recordings. Both provide good quality at manageable file sizes (1 MB per minute at 128 kbps).
What is the difference between 128 kbps and 320 kbps?
At 320 kbps the difference from lossless audio is inaudible to most people. At 128 kbps there is a slight reduction in high-frequency detail, particularly noticeable on headphones with complex music.
Can I compress WAV or FLAC files?
Yes. WAV and FLAC can be compressed to MP3 or AAC. The resulting file will be much smaller. Note that this converts from lossless to lossy format.
What is the maximum file size supported?
Audio files up to 200 MB are supported.
Does compression change the audio duration?
No. Compression only reduces audio quality and file size — the playback duration remains exactly the same.
