What is it?

Reframe is a browser-based video editor built with Next.js and FFmpeg.wasm. All processing happens on the user's device, so video files are never sent to a server and no account is required.

It focuses on common quick edits: resizing videos to preset social media formats such as Reels, TikTok, YouTube and Instagram, or to custom dimensions, with Fit (letterbox) or Fill (crop) framing. Users can also trim start and end times, rotate by 90-degree steps, mute audio, change playback speed from 0.25x to 4x, and adjust a CRF quality slider before export.

The project is MIT-licensed and can be run locally with Bun or Node.js, or deployed as a static site to Vercel, Netlify, GitHub Pages or Cloudflare Pages. Deployment on Vercel requires COOP/COEP headers for SharedArrayBuffer support.
