About Cutmoor — the browser media toolkit
Cutmoor is a small set of video and image tools that run in your browser. It exists because the everyday jobs around short-form media are boring, repetitive, and usually require a trip through an upload form on someone else's server.
Drop a file, choose a preset, get a clean export. The file is processed on your device. There is no account, no storage bucket, and no queue.
Last updated 2026-11-11Who it is for
Creators who need a Reel to fit a size limit. Small teams making product clips and social images on a laptop. Anyone who has recorded a video and discovered it is 180 MB when the app accepts 25 MB, or exported a photo that a job portal refuses because it is 6 MB.
The tools are deliberately narrow. Cutmoor is not an editor, a timeline, or a replacement for Premiere, Final Cut, CapCut, or Photoshop. It is the step after editing: make the file fit, make it the right shape, and get it out.
Why local processing
Uploading a video or photo is slow, costs the operator bandwidth, and creates a copy of your file on a machine you do not control. Running the encoder in the browser avoids all three.
Video is handled by a WebAssembly build of FFmpeg. Images are decoded and re-encoded with the browser's canvas API, with a lazily loaded HEIC decoder where the operating system does not provide one. The tradeoff is honest: browser processing is limited by the memory of your device. Very large files, especially on phones, can fail. Cutmoor shows the limit before you start and never pretends a job succeeded when it did not.
What Cutmoor does not do
Cutmoor does not download videos from YouTube, Instagram, TikTok, or any other platform. It only works with files you already have and have the right to use.
It does not upload, store, or share your files. It does not require an account, and it does not add a watermark.
