Frequently asked questions

Are audio files uploaded to a server?
The current browser-based audio tools process selected files locally. The audio engine may download code when first used, but your recordings are not uploaded to a conversion service.
Which audio formats are supported?
Audio Converter offers MP3, WAV, FLAC, M4A, OGG Vorbis, and AAC output. Available inputs and export options vary by tool, so check the tool page for its supported formats.
Do I need an account to use the audio tools?
No account is required for the current local audio tools. Open a published tool, choose a supported file, and start processing in your browser.
Can I work with multiple audio files?
Yes, for tools that support batches, such as Audio Converter and Audio Joiner. Other tools may accept one file at a time. Each page shows its own file and size limits.
Will converting an audio file improve its sound quality?
Changing formats or increasing bitrate cannot restore details already lost in a compressed recording. Choose WAV or FLAC when compatible lossless output is needed, and consider the quality of your source.
Can I use AudioBento on a phone?
The tools support mobile browsers, but mobile devices generally have less memory available for large or lengthy recordings. Some tools therefore use lower mobile file limits.
Are there limits on file size or duration?
Yes. Limits depend on the tool and device, and browser memory may further restrict processing. Check the upload area of the chosen tool before working with a large file.
Where do my finished audio files go?
Download completed outputs to save them on your device. Results generated by local tools are not permanent cloud storage, so save what you need before closing or refreshing the page.
