Crop Video to 9:16 for TikTok, Reels & Shorts

Resize a video to 9:16 online, free, without sending it anywhere. Crop for TikTok, Reels, or Shorts, or fit the whole frame on a blurred background. The MP4 has no watermark.

Frame

Drag the preview to move a crop. Blurred fit keeps the whole picture. Safari 26 is required on iPhone. Cancel closes the cropper.

InBrowserConvert Pro (coming soon): batch, bigger files, no limits, still 100% on-device. $29 lifetime or $19/yr.

A vertical frame without an upload

Crop video to 9:16 here means the browser cuts or fits the frame. Nothing is posted to a conversion API. The header should stay at 0 bytes uploaded.

Center is the default. Dragging moves the window. Blurred fit is the option when a hard crop would cut someone off.

How to convert

  1. 1. Add an MP4, MOV, or WebM

    Drop the video or choose it on this phone or computer. The picker hands the file to the page. It is not sent to a server.

  2. 2. Place the 9:16 frame

    Crop starts in the center. Drag the preview to move the window. Switch to blurred fit when you want the whole picture, with the spare space filled by a soft copy of the same frame.

  3. 3. Download the vertical MP4

    The file is H.264 and AAC, with no watermark. A phone keeps the long edge around 1280 pixels. A computer can go to 1080 by 1920, and it does not enlarge a small video. Cancel closes the cropper. One video runs at a time.

Questions

Can I resize video to 9:16 online free?

Yes. Online here means the page is in the browser. The video stays on this device. There is no account, no daily cap, and no watermark. A phone still stops around 160 MB and a computer around 400 MB, so the tab is not killed.

How do I convert video to vertical?

Choose Crop to cut a 9:16 window out of a landscape video, or Blurred fit to keep the whole frame and fill the sides. Both save a vertical MP4. Drag the preview when you want the window somewhere other than the center.

Can I convert video to vertical for YouTube Shorts?

Yes. Shorts, Reels, and TikTok all use 9:16. This page does not post the video to YouTube. It only makes the vertical file. You upload that file yourself if you want it on Shorts.

Can I crop video for TikTok?

Yes. The crop is 9:16, which is the TikTok frame. Drag left or right on a wide video to keep the part you want. The result is an MP4 with no watermark from this site.

Does it work on iPhone?

In Safari 26 or newer, which can encode H.264. Older iOS shows an error and does not upload the video. A phone also uses a smaller 9:16 frame, about 720 by 1280, so the tab stays usable.

Which files does this page actually accept?

MP4, MOV, and WebM. The download is one MP4. Other video types are refused, and they are not uploaded.
