How this works
Your browser plays the whole video while center-cropping every frame to fill YouTube Shorts' 9:16 vertical frame and drawing it onto a canvas, then records that canvas — combined with the original audio — into a new WebM file. No video is uploaded, and no server-side conversion is involved.
A note on scope
The video is center-cropped (not stretched) to fill the vertical frame, so the sides of a wide shot may be trimmed off. Because recording happens in real time, resizing takes roughly as long as the video's own length. The output is a WebM file, which plays natively in all current browsers and most apps.
Common use cases
- Reformat an existing landscape video for YouTube Shorts
- Turn a horizontal recording into a vertical Shorts upload
- Quickly fit any video to Shorts' 9:16 frame
Frequently asked questions
Is this YouTube Shorts resizer free?
Yes. It is completely free, with no signup and no watermark.
Is my video uploaded anywhere?
No. The video is resized entirely in your browser. Nothing is sent to Inqita or stored.
Will this stretch my video?
No. It center-crops the frame to fill the 9:16 shape without distortion, so the far left and right edges of a wide shot may be cut off.
Does this also trim the video's length?
No, this tool only resizes the frame. Use the Video Cutter or TikTok Video Cutter tool first if you also need to trim the clip's length.
What format is the output?
WebM, a widely supported video format that plays in all current browsers, and can be uploaded to YouTube from most devices.
