Make a recording easier to share
Compress or convert it to a format and bitrate supported by the destination.
Audio tools
Online audio conversion, compression, trimming, and extraction
Convert or compress common audio formats, trim a clip, or extract an audio track from video. Audio defaults to on-device processing. Cloud mode is available for long recordings, batches, or devices with limited memory.

Keep the audio task clear
Convert audio when a device, editor, or upload destination requires another format. Compress when file size is the problem. Trim when you only need a section of a recording. These operations can re-encode the sound, so the chosen format and bitrate affect quality as well as size.
Audio Extraction starts from a video and saves its existing sound track as an audio file. It does not improve the source recording or separate speech from music. Use it as the first step before trimming, converting, or compressing the extracted audio.
Organized around real tasks
Common audio workflows
Save one section
Trim a clip by setting its start and end times, then check the playback before sharing.
Pull sound from a video
Extract the existing audio track, then continue with a separate audio tool if needed.
Prepare a known format
Convert a file for an editor, player, device, or upload requirement.
A reliable audio workflow
Choose the source type
Use an audio file for convert, compress, or trim; use a video file for audio extraction.
Set only the needed options
Choose the output format and adjust bitrate, sample rate, channels, or time range when the tool offers them.
Listen before sharing
Check the duration and sound of the output. Keep the original when quality matters.
Audio tool questions
Does converting audio improve sound quality?
No. Conversion changes the encoding or container. It cannot restore detail already removed from the source, and a lower bitrate may reduce quality further.
Should I compress or convert my audio?
Compress when the file is too large. Convert when a device, editor, or platform requires another format. You can do both if the workflow needs them.
Can audio extraction separate speech from music?
No. Audio Extraction saves the existing audio track from a video. It does not isolate voices or instruments.
Why does a long recording take time?
Longer files need more decoding and encoding work. Cloud mode can reduce device load, but adds upload and queue time; it does not guarantee a shorter total wait.
