About MediaFun

MediaFun is a free, browser-based multimedia processing platform. We provide 11 powerful tools for editing, converting, and compressing video, audio, and GIF files — all without uploading your files to any server.

Our Mission

We believe that basic multimedia editing should be free, fast, and private. Too many online tools require you to upload your files to remote servers, waiting in queues, dealing with file size limits, and trusting third parties with your personal content.

MediaFun takes a different approach: everything runs in your browser. Using the power of WebAssembly and ffmpeg.wasm, we bring professional-grade multimedia processing directly to your device. Your files never leave your computer.

How It Works

MediaFun uses FFmpeg — the industry-standard multimedia framework — compiled to WebAssembly so it runs natively in your web browser. This means:

  • 100% Private: Your files are processed locally and never uploaded anywhere
  • No waiting: Processing starts immediately — no upload queue
  • No file size limits: Process files up to 500MB (browser memory permitting)
  • No account required: Just open a tool and start processing
  • Free to use: All basic tools are completely free

What You Can Do

Our tools cover a wide range of multimedia tasks:

  • Video: Compress, convert, trim, rotate, change speed, remove audio, take screenshots
  • Audio: Extract audio from video, convert between audio formats
  • GIF: Compress GIFs, convert videos to GIF

We're constantly adding new tools to help you work with your media files more efficiently. Explore all tools →
