Audio Bitrate Changer
Adjust the bitrate of any audio file to balance quality and file size — free, instant, and 100% in-browser.
Audio bitrate controls the balance between file size and sound quality — the higher the bitrate, the better the audio but the larger the file. Whether you're preparing audio for a podcast, reducing file size for web upload, or re-encoding a track for a specific platform, our free online Audio Bitrate Changer lets you set any bitrate from 32 kbps to 320 kbps instantly. No account, no software download, and your files never leave your browser.
How to Change Audio Bitrate Online
- Upload your audio file — Drag and drop or click to browse. Supports MP3, AAC, OGG, WAV, and FLAC files.
- Choose your target bitrate — Select from common presets (64, 128, 192, 256, 320 kbps) or pick a custom value.
- Preview your settings — The tool will estimate the output file size based on your chosen bitrate and audio duration.
- Click "Change Bitrate" — Processing happens entirely in your browser using the Web Audio API.
- Download your file — Save the re-encoded audio to your device, ready to use.

Frequently Asked Questions
What is audio bitrate?
Audio bitrate is the amount of data used per second of audio, measured in kilobits per second (kbps). A higher bitrate means more data, which typically results in better sound quality but a larger file size. Common values are 128 kbps (standard quality), 192 kbps (good quality), and 320 kbps (near-lossless quality for MP3).
What bitrate should I use for my audio?
For podcasts and voice-only recordings, 64–96 kbps mono is usually sufficient. For music streaming, 128 kbps is acceptable and 192–256 kbps is considered high quality. Use 320 kbps when you need the best possible MP3 quality. For archiving, consider keeping lossless formats like WAV or FLAC.
Will reducing the bitrate permanently damage my audio quality?
Yes — lowering the bitrate of a lossy-encoded file (MP3, OGG, AAC) is a one-way process. The audio data removed during compression cannot be restored. Always keep a backup of your original file before reducing the bitrate.
Can I increase bitrate to improve audio quality?
No. Increasing the bitrate of an already-compressed file does not restore lost audio data. It will only result in a larger file with the same (or marginally worse) perceived quality. Increasing bitrate is only meaningful when starting from an uncompressed or lossless source.
What's the difference between bitrate and sample rate?
Bitrate (kbps) controls how much data is used per second to represent the audio. Sample rate (Hz, e.g. 44100 Hz or 48000 Hz) controls how many audio samples are captured per second. Both affect quality and file size, but bitrate is the most common lever for balancing quality vs. size in compressed audio files.
What file formats does this tool support?
The tool accepts MP3, OGG, WAV, AAC (M4A), and FLAC files. Output is encoded as MP3 since it's the most universally compatible compressed audio format and supports the full range of bitrate settings.
Is there a file size limit?
No. Because processing happens entirely in your browser using the Web Audio API, there's no server-side file size restriction. Large files may take longer to process depending on your device's speed.
Is my audio file uploaded anywhere?
No. Your audio is decoded and re-encoded entirely within your browser window. No data is transmitted to any server at any point. Your files remain completely private.
