Millwards Studio is a browser-based video clipper for creators. Upload a video you own, trim the hook, choose a vertical (9:16), square (1:1) or landscape (16:9) layout, add captions and export. Free exports run in your browser at 720p; Pro gives 1080p MP4 exports with no watermark plus AI highlight suggestions. Nothing is uploaded unless you choose a Pro export or save a project.
Built for TikTok, Instagram Reels and YouTube Shorts: safe-zone overlays, caption length limits and aspect-ratio presets are built in. Use the tools and guides below to pick the right size for each platform.
