About this tool
YouTube Shorts are vertical (9:16) videos, best at 1080×1920. Videos that are square or vertical and short enough are treated as Shorts.
Pick one of the sizes below the picture area. If your video has a different shape, choose how to fill the frame: a blurred copy of the video behind it, black bars, or cropping the edges to fill.

Frequently asked questions
Is my video uploaded to a server?
No. Everything runs inside your browser tab using your own device's video hardware. Your file is never sent to ToolsCrow or anyone else, which also means there is no waiting for an upload and it keeps working if your connection drops after the page has loaded.
Is it really free? Is there a watermark?
It is free with no sign-up, no watermark and no daily limits. The only limits are the ones your device sets: memory and processing power.
How large a video can I use?
Because the video is processed on your device, the limit is your device's memory rather than a server quota. Phone clips of several hundred MB are fine on most devices, and desktop computers usually handle 1 to 2 GB. Files over about 4 GB are not supported.
Which browsers work best?
Current Chrome, Edge and Safari (16.4 or newer, including iPhone and iPad) work best because they include the WebCodecs video engine. Recent Firefox versions work for many files. Older browsers fall back to a much slower real-time mode or may not work at all.
What size should a YouTube Shorts video be?
YouTube Shorts are vertical (9:16) videos, best at 1080×1920. Videos that are square or vertical and short enough are treated as Shorts.
Should I use the blurred background?
It is usually the best-looking choice when the shape changes, because the picture stays complete. Use "Fill" only if you do not mind cropping the edges.
