Turn client Looms, screen recordings and voice notes into developer-ready tasks, bugs, design changes, screenshots and acceptance criteria: each traceable to the moment it was asked for.
Video Converter
Convert video between MP4, WebM, MOV, AVI, MKV and GIF in your browser with FFmpeg. Pick a target format, tune MP4 quality, preview the result and download. Nothing is uploaded.
Extract Audio from Video
Pull the audio track out of any video and save it as MP3, WAV, AAC, M4A or OGG, right in your browser. Drop an MP4, MOV or WEBM, pick a format, preview and download. Nothing is uploaded.
Video to GIF
Turn a video into a high-quality animated GIF right in your browser. Pick a start, duration, frame rate and width, get a two-pass palette for clean color, then preview and download. Nothing is uploaded.
GIF to Video
Convert an animated GIF into a smaller, smoother MP4 or WebM right in your browser. Modern video compression typically shrinks a GIF to a fraction of its size and plays back cleaner, and nothing is ever uploaded.
Video Player
A clean, private video player that runs in your browser, play any local MP4, WebM, MOV or MKV with variable speed, A→B loop, Picture-in-Picture, fullscreen and frame-by-frame stepping. Nothing is uploaded, nothing is processed.
MP4 to WebM
Convert MP4 to WebM (VP9) in your browser: a leaner, royalty-free format that streams natively in modern browsers. Tune the quality, preview the result and download. Nothing is uploaded.
WebM to MP4
Convert WebM to MP4 (H.264) in your browser, the universally compatible format that plays on iPhones, in editors and on social. Preview the result and download. Nothing is uploaded.
