Cut long videos into platform-ready segments
A browser-based tool that splits a long video into fixed-length segments sized for Instagram Reels, YouTube Shorts and TikTok. Upload once, pick a duration, download every part.
Key Features
Pick 60s, 90s, or 180s to match the platform you're posting to, or enter a custom length.
FFmpeg output streams back to the browser over server-sent events with a running percentage and log.
Every segment is re-encoded to H.264 at CRF 23 with AAC audio, so the parts are uniform and upload-ready.
The uploaded source file is deleted from the server once processing finishes.
Why We Built This
Every platform has a different clock
Reels cap at 90 seconds, Shorts at 3 minutes, TikTok clips at 60. Getting one long recording onto all of them meant opening an editor and manually trimming the same file over and over, then exporting each part by hand. This tool wraps FFmpeg's segment muxer in a drop-and-go web page: choose the target length, upload the file, and get back a numbered set of clips already encoded to H.264/AAC and ready to post.
60 seconds for TikTok and Shorts, 90 for Instagram Reels, 180 for longer Shorts — or type any custom length from 10 to 600 seconds.
FFmpeg's segment muxer cuts the whole file in a single run and resets timestamps, so each clip plays cleanly from zero.
The server verifies each generated part has real content and returns a direct download link per clip.
