A free toolbox that turns your browser into a video studio — your files never leave your device.
Steenox is a free online video toolbox. It gives you the everyday video jobs most people need — converting between formats (MP4, WebM, MOV), compressing large files, trimming clips, extracting MP3 audio, turning short clips into GIFs, designing YouTube thumbnails, and even generating hashtags and video titles — all from a single web page, with nothing to install and no account to create.
Everything happens locally, inside your own browser, using proven open-source video technology (FFmpeg, running as WebAssembly). The process is simple: you pick a tool, choose your video file, press the button, and download the result. Your file is processed on your device — it is never uploaded to our servers, because we don't have servers that receive files. There is nothing to sign up for and no watermark added to your output.
An honest boundary: Steenox works with your own video files — videos you recorded, received, or have the right to use. Our tools cannot download videos from YouTube, TikTok, Instagram, Facebook or any other platform, and they cannot fetch a video from a link. If you need a copy of a video from one of those platforms, please use that platform's own official download or sharing options.
Because the expensive part of a video service — the servers that process files — doesn't exist here. Your device does the work, so there is almost nothing for us to pay for. That keeps Steenox free, without accounts, subscriptions or catch.
