How it works
The browser decodes the source video, draws each frame into a canvas at the selected platform dimensions, and records the canvas stream with MediaRecorder. It also retains source audio when the browser exposes the audio track.
When to use this tool
- Preparing a vertical clip for TikTok, Shorts, Reels, or Snapchat Spotlight
- Creating square or portrait social feed videos
- Making a landscape export from a vertical or square source
Frequently asked questions
Can I choose whether the video is cropped?
Yes. Fill frame center-crops the source to cover the target frame; Fit entire video keeps the whole image and fills the unused space with bars.
Does this upload my video?
No. The video is decoded, reframed, and recorded locally in your browser.
Will audio be kept?
Audio is retained when your browser can capture the source video audio track. Browser codec support varies.
Limitations
Encoding runs in real time and browser video encoder support varies. Large or high-resolution files can require substantial memory. The platform presets set aspect ratio and dimensions; they do not guarantee each platform’s latest publishing specifications.
Privacy
Your selected video remains on your device and is processed in browser memory.
