What Is an Audio Converter?
An audio converter is a tool that changes audio files from one format to another. Whether you need to convert MP3 to WAV for professional editing, FLAC to MP3 for portable playback, or M4A to MP3 for universal compatibility, an audio converter handles the re-encoding process while letting you control output quality.
Convertr's online audio converter supports 40+ formats and runs entirely in your browser — no software to install, no account to create. Upload your file, pick a target format, adjust settings like bitrate and sample rate if needed, and download the result in seconds.

Upload your MP3 file using the converter above, select WAV or FLAC as the output format, and click Convert. Your file will be ready to download in seconds.
Converting between lossless formats (WAV, FLAC, AIFF) preserves full quality. When converting to lossy formats (MP3, AAC, OGG), you can set the bitrate to control quality. Higher bitrates (256-320 kbps) produce near-lossless results.
Yes. Your files are processed securely and automatically deleted from our servers after conversion. We never store, share, or access your files.
Yes, Convertr works on any device with a web browser — iPhone, Android, iPad, or desktop. No app installation required.
MP3 is a lossy format that compresses audio by removing data the human ear is less likely to notice, resulting in smaller files (typically 3-10 MB per song). FLAC is a lossless format that compresses audio without any quality loss, producing larger files (15-40 MB per song) identical to the original recording. Choose MP3 for portability and FLAC for archival quality.
Upload your M4A file (common on iPhones and iTunes) to the converter above, select MP3 as the output format, optionally set your preferred bitrate (we recommend 256 or 320 kbps for high quality), and click Convert. The MP3 file will be ready to download in seconds.
For general listening, 192 kbps offers a good balance between quality and file size. For high-quality music, use 256 or 320 kbps — most people cannot tell the difference from the original. For speech or podcasts, 128 kbps is sufficient. Lower bitrates (64-96 kbps) save space but noticeably reduce quality.
Yes! Convertr supports batch audio conversion. Upload multiple files at once, select the same or different output formats for each, and convert them all in one go. Each file can be up to 1 GB.
For the best quality, use lossless formats like FLAC or WAV — they preserve the original audio perfectly. FLAC is preferred because it compresses the file to roughly half the size of WAV without any quality loss. If file size matters, AAC at 256 kbps or MP3 at 320 kbps provide excellent quality that most listeners cannot distinguish from lossless.
