Audio Editor
Trim, change speed and adjust volume of any audio file: MP3, WAV, FLAC, OGG, M4A
Audio Editor Online - Trim, Speed and Volume Control Free
EzyIMG's Audio Editor combines three essential audio editing functions into a single tool: trimming, speed adjustment, and volume control. Upload an MP3, WAV, FLAC, OGG, M4A, AAC, or OPUS file, then use the waveform timeline to drag start and end trim points to remove silence or unwanted content. Set playback speed anywhere from 0.25x to 4x. Speed up recorded lectures to 1.5x or 2x without pitch distortion, or slow down a fast passage for transcription. Boost quiet recordings by setting volume to 150–200%, or reduce overly loud audio. Choose MP3, WAV, FLAC, or OGG as the output format and click Apply. A practical everyday use is speeding up long meeting recordings before sharing, or trimming a song to a specific hook before merging with other tracks.
All processing is done entirely in your browser using FFmpeg compiled to WebAssembly, and no audio file is ever sent to a server. There is no account required, no watermark on the output, and no file size limit imposed by a backend. The waveform display helps you identify the right trim point visually so you can cut precisely. Use WAV output for lossless quality when the trimmed audio will be edited further, or MP3 for the smallest file size when sharing.
