About Vertical Video Converter (16:9 → 9:16)

A vertical video converter that reframes landscape (16:9) video to vertical 9:16, square 1:1 or portrait 4:5 for TikTok, Instagram Reels and YouTube Shorts — entirely on your device using the browser's WebCodecs engine. Choose Crop to drag a sharp full-height window over the video, or Blur-pad to keep the whole frame on a blurred, zoomed background. Nothing is uploaded and there is no watermark.

How to use Vertical Video Converter (16:9 → 9:16)

  1. Drop in a video (MP4, MOV, WebM, MKV or MPEG-TS, up to 2 GB) — it is read locally and never leaves your browser.
  2. Pick a target aspect: 9:16 for TikTok/Reels/Shorts, 1:1 square, 4:5 portrait feed, or 16:9 to go the other way. The exact output size is shown for your source.
  3. Choose a mode — Crop drags a sharp window across the video (pointer, touch or arrow keys); Blur-pad keeps the entire frame inside a blurred backdrop.
  4. Optionally switch on Safe zones to see where TikTok/Reels/Shorts UI (right action rail, captions, status bar) will cover your video — preview only, never exported.
  5. Pick MP4 or WebM, click Reframe and watch the progress bar (you can cancel anytime).
  6. Preview the result and save it — audio passes through untouched.

Frequently asked questions

Is my video uploaded to a server?
No. The whole reframe runs inside your browser using WebCodecs — the file is read from your device, every frame is cropped or repainted on your device, and the result is saved back to your device. Nothing is uploaded, there is no signup and no watermark.
Should I use Crop or Blur-pad?
Crop keeps a sharp full-height window and cuts away the rest — best when the action sits in one part of the frame; drag the window to choose what stays in view. Blur-pad keeps the entire original frame, scaled to fit, and fills the empty space with a blurred, zoomed copy of the video — best for screen recordings, sports or anything where cutting the sides would lose information.
What resolution do TikTok, Reels and Shorts want?
All three are built around 1080×1920 (9:16). In Blur-pad mode the tool outputs exactly that platform-standard size (scaled down only if your source is smaller, so nothing is upscaled). In Crop mode the window is cut straight from the source pixels — a 1920×1080 video yields a sharp 608×1080 crop, which platforms accept and scale themselves.
Can it convert portrait video to landscape too?
Yes. Pick the 16:9 target and the same two modes work in reverse: Crop slides a full-width window up and down a portrait video, and Blur-pad places the whole portrait frame on a blurred 1920×1080 canvas — handy for reusing phone footage on YouTube.
What are the safe zones?
Translucent outlines showing where TikTok, Reels and Shorts typically draw their own UI over your video: roughly the top 8% (status/search), the right 12% (like/comment/share rail) and the bottom 20% (caption, sound and profile info). Keep faces, text and logos out of those bands so they aren't hidden. The overlay is a preview aid only — it is never drawn into the exported file.
