Convert MP3, WAV and OGG audio, trim or join clips, normalize loudness and view waveforms online for free. Browser FFmpeg uses device memory; test short clips and check playback.
Use this tool for free without a KitNelo account. Processing runs in your browser; input limits, browser support and device memory still apply.
Downloads FFmpeg resources and uses device memory. Start with short clips; support depends on the input codec and browser.
Read KitNelo data and privacy detailsSelect a supported audio source, choose MP3, WAV or OGG output and run the browser conversion. Play the downloaded file to confirm it works, since input codec support and available device memory affect processing.
Load an audio file and choose the portion to keep before exporting the shortened clip. Listen to its beginning and ending to confirm the cut points, starting with short clips while browser FFmpeg resources load.
Add the audio files to join and check their intended order before creating one output. Listen across the joins in the exported track to confirm the sequence and detect gaps or unexpected transitions.
Choose the loudness normalization operation for a supported audio file and export the processed track. Compare playback with the original to assess level changes, checking that the result suits the platform where you plan to use it.
Open a supported audio file to inspect its waveform while reviewing the clip. Use the visual pattern alongside playback to locate relevant moments; a waveform view does not establish how the audio sounds on its own.
