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.
How to Use
- 1
Upload your audio file
Drop any MP3, WAV, FLAC, OGG, M4A, AAC, or OPUS file into the upload area.
- 2
Use the waveform timeline to set trim points
Drag the start and end trim points on the waveform to define the output segment. Enable the Trim checkbox to activate trimming.
- 3
Adjust playback speed (optional)
Use the speed presets (0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x) or the custom slider to slow down or speed up the audio.
- 4
Adjust volume (optional)
Use the volume slider to boost (up to 400%) or reduce (down to 0%) the audio level.
- 5
Choose output format and apply
Select MP3, WAV, FLAC, or OGG as the output format and click Apply. Download the processed audio.

Frequently Asked Questions
Is there any cost to use the Audio Editor?
No, it's free to use, with no account requirement, no watermark, and no file size limit.
Does my audio file get uploaded anywhere while editing?
No. Trimming, speed, and volume changes are all processed in your browser using FFmpeg compiled to WebAssembly. Your file never leaves your device.
Which audio formats can I load and export?
Input: MP3, WAV, FLAC, OGG, M4A, AAC, OPUS. Output: MP3, WAV, FLAC, or OGG.
Does changing the speed also shift the pitch?
No. The speed control uses FFmpeg's atempo filter, which changes tempo while keeping the pitch the same, so a sped-up voice doesn't sound higher and a slowed-down one doesn't sound lower.
Will speeding up my audio hurt its quality?
Tempo changes via atempo don't degrade quality on their own. The final quality mostly comes down to your chosen output format, use FLAC or WAV if you want a fully lossless result.
