How to compress audio files
Open Audio Compressor, choose an output format and compression setting, then create a smaller copy of the audio file. You can choose MP3, AAC, OGG, or WAV output, set a bitrate preset, or work toward a target size. The page also shows duration and output-size estimates and supports batch processing. Files stay local in your browser, with no upload.
What the audio compressor can change
Start with the output format. Audio Compressor can create MP3, AAC, OGG, or WAV files. Then choose a bitrate preset when you want to set compression by bitrate.
Target-size mode sets up compression around a file-size requirement. The duration and output-size estimates give you two details to check before creating the compressed copy. Batch processing lets you add multiple audio files to the same job.
Input: audio file produces Output: compressed MP3 audio file when MP3 is selected.
How to reduce audio file size with target-size mode
Use target-size mode when the compressed file needs to meet a size requirement. Bitrate presets let you choose a compression setting instead. Check the duration and output-size estimates before you create the file.
For several files, use batch processing on the same page. Choose MP3, AAC, OGG, or WAV output for each compression job.
Typical jobs for Audio Compress Tools
- You need a smaller audio file for delivery. Open Audio Compressor, choose the output format, and create a compressed copy.
- You need the file to meet a size requirement. Use target-size mode and check the output-size estimate before creating it.
- You have several audio files to prepare. Add them to a batch instead of setting up each file as a separate job.
- You need different output formats for different destinations. Select MP3, AAC, OGG, or WAV in Audio Compressor.
When to use Audio Tools instead
Use Audio Compress Tools when you need to reduce audio file size. For conversion, trimming, cleaning, merging, tagging, recording, or analysis, open Audio Tools. This category has one child tool, Audio Compressor.
Frequently asked questions
How do I compress audio files for a smaller output?
Open Audio Compressor, choose an output format and compression setting, then create the compressed copy. Use a bitrate preset or target-size mode to set the compression.
Which formats can an audio compressor output?
Audio Compressor can output MP3, AAC, OGG, or WAV files. Choose the format needed for the next step.
Can I reduce an audio file to a target size?
Yes. Use target-size mode to set up a file-size target, then check the output-size estimate while choosing compression settings.
Does Audio Compressor upload audio files?
No. Audio Compressor works locally in your browser, with no upload.
