Batch File Conversion

Need to convert many files? Our batch converter processes multiple audio and video files simultaneously. Drag in a folder's worth of files and convert them all at once - saving hours of repetitive work.

Converting Multiple Files

Simply drag all your files into the converter. Select your desired output format and quality settings. Click convert, and each file is processed independently. Download completed files individually or all at once.

Benefits of Batch Conversion

Converting files one by one is tedious. Batch processing lets you set up the conversion once and walk away. It's perfect for standardizing file formats or preparing multiple files for a project.

Multiple File Conversion Uses

Converting an entire folder of audio files to MP3
Extracting audio from multiple video files
Standardizing format across a collection
Preparing multiple files for a project or platform

Private Batch Processing

Every file in your batch is processed locally. Whether you're converting 2 or 200 files, none are uploaded anywhere.

Format Guide & Compatibility

Use this quick guide to choose the right output settings for MP3 conversion.

Use MP3 when you need maximum device and app compatibility.
If quality is critical, compare MP3 output with lossless options like WAV or FLAC.
MP3 usually delivers smaller file size for sharing and storage.
Popular workflows for this tool include MP4 -> MP3, WAV -> MP3, FLAC -> MP3.
All conversion runs locally in your browser, so your source files stay on your device.

MP4 vs MP3 vs WAV vs FLAC

Format	File Size	Quality	Best For
MP4	Small	Good	Everyday listening, universal sharing
MP3	Small	Good	Everyday listening, universal sharing
WAV	Large	Lossless	Editing and archiving raw quality
FLAC	Large	Lossless	Long-term archival and high-fidelity audio

Troubleshooting

File is not supported

Re-export your source file in a common format and try again. Corrupted files may fail to decode.

Output has no audio

Your source may not contain an audio track, or it may use an uncommon codec. Try another source file to confirm.

Conversion is slow

Close heavy browser tabs and background apps. Local conversion speed depends on your device CPU and file size.

Large files fail

Split very large files into smaller parts or use a shorter clip first, then convert full media on a more powerful device.

Frequently Asked Questions

How many files can I convert at once?

There's no hard limit, but your device's memory matters. Most devices handle 20-50 average-sized files well. For very large batches, process in groups to avoid memory issues.

Will all files be converted to the same format?

Yes, you set one output format and quality that applies to all files. If you need different formats, run separate batches. This ensures consistency.

What if one file fails?

Files are processed independently - one failure doesn't affect others. Failed files show error messages while successful conversions continue normally.

Can I mix audio and video files in one batch?

Yes! Videos will have their audio extracted, and audio files will be converted to your chosen format. All outputs will be audio files in your selected format.

How do I download all converted files?

Download individually as files complete, or use 'Download All' for a single action. Most browsers prompt you to allow multiple downloads.
