Frequently Asked Questions
Are my video or audio files uploaded?
No. We utilize FFmpeg compiled to WebAssembly (ffmpeg.wasm) to process video and audio directly inside your browser. No files are uploaded to any server.
Why does the tool take a moment to load?
The first time you load a video tool, your browser downloads the FFmpeg WebAssembly binaries. Subsequent visits will load instantly from your browser's cache.
Can I use these tools offline?
Yes. Once the page is loaded, all processing runs locally on your machine, so you don't even need an active internet connection.
