About these tools
These tools use the browser's Web Audio and media APIs to work with files on your device. Cut a section out of a song or a recording, raise the volume of a quiet clip, or check which files in a folder are exact duplicates.
Browser-based media processing has trade-offs that the tool pages spell out: audio is saved as WAV, trimmed video is recorded in real time and saved as WebM, and large files need plenty of memory.
Typical uses
Examples of everyday tasks these tools are built for.

Frequently asked questions
Why is the output WAV or WebM instead of MP3 or MP4?
Browsers can create WAV audio and WebM video natively. Encoding MP3 or MP4 would need extra software, so these tools use the formats the browser supports reliably.
Are my media files uploaded?
No. Files are opened and processed inside your browser tab.
