Tools
Video tools that run on your own machine, in a browser tab. Nothing uploads — which is also why they are free, have no size limit and add no watermark.
Everyday
The things footage usually needs before anything else.
Trim Video
Drag the handles to the part you want, preview it, save it. Audio stays in sync.
Open →Compress Video
Make a file smaller and see exactly what it cost. No size limit, because there is no server.
Open →Video to MP3
Pull the audio out of a video and keep it as MP3, WAV or OGG.
Open →Convert Video
MP4, WebM and MOV in any direction — or pull the audio out as WAV.
Open →Made with the engine
These read what is in the video, which is the part other tools skip.
Video Splitter
Cut a long video into Reels or Shorts that start on a shot change instead of every 30 seconds, ranked by picture quality.
Open →BPM Detector
Find a track’s tempo and the time of every beat, then send the grid to Resolve, Premiere, Final Cut or Audacity as markers.
Open →Scene Detector
Find every cut in a video and get the shot list with thumbnails, timecodes and quality scores.
Open →Why these exist
Life2Film analyses footage and assembles it into a montage. That engine is a set of separable parts — one finds the beat in music, another finds the cuts in a video, another decides which moments are worth keeping.
Each part is useful on its own, and each is small enough to run in a browser tab. So rather than describe what the engine does, these pages let you run it.
The whole thing works without a server. Your file is read into memory, analysed by WebAssembly compiled from the same Rust the app uses, and forgotten when you close the tab. There is no account, no queue and no upload — not as a privacy promise, but as a fact about how the page is built.
Use the engine yourself
The analysis behind the last three tools is published as a package. It finds the beat in music, the cuts in a video, and scores frames for picture quality — in a browser tab or in Node, with no server and no API key.
