What Is the Free Media Toolkit?

The Free Media Toolkit is a growing collection of browser-based tools for working with audio and video files. Every tool runs entirely in your browser using WebAssembly (ffmpeg.wasm) — your files never leave your device, there's nothing to install, and no account is required.

Whether you need to merge hundreds of audiobook chapters into a single M4A, convert between audio formats, compress a video before sharing, or trim a clip, the Media Toolkit has a dedicated sub-tool for the job. Each tool is individually optimized for its task, so you get a focused, fast experience instead of a bloated all-in-one editor.

Why Use Browser-Based Media Tools?

  • No installation— Works on any modern browser including Chromebooks and locked-down work machines where you can't install software.
  • No sign-up — Most online media tools require an account or limit free usage. Every tool here is completely free with no restrictions.
  • No file size limits— The only limit is your browser's available memory (typically 1-2 GB on desktop).

Frequently Asked Questions

How does this work without uploading my files?

The Media Toolkit uses ffmpeg.wasm — a WebAssembly port of the industry-standard ffmpeg library. It runs entirely in your browser tab. Your files are read from disk into browser memory, processed by the WASM engine, and the output is downloaded directly to your device.

Is there a file size limit?

There's no artificial limit. The practical limit is your browser's available memory — typically 1-2 GB for the combined size of all input files. A warning appears if your files exceed 1 GB total.

Which browsers are supported?

Any modern Chromium-based browser (Chrome, Edge, Brave, Opera) and Firefox. Safari has limited WebAssembly support and may not work with all tools. Desktop browsers are recommended for the best performance.
