Resize a Video for TikTok, Reels and Shorts (9:16)

Turn a landscape video into a 1080 × 1920 vertical video: the whole picture on a blurred background, or cropped to full screen.

The editor is designed for a computer or a tablet: open this page on a larger screen to edit your video.

100% local processing, nothing is uploaded

How does it work?

The 9:16 format (1080 × 1920 in 1080p) is applied straight away. Drop your video: if it is landscape, it is shown in full in the center, on a blurred background taken from the video itself, as on TikTok.

Prefer full screen? Choose “Fill” on the right: the video covers the whole frame and its sides are cropped. You can also add a title or music, or trim the video before exporting.

The resulting MP4 file suits TikTok, Instagram Reels and YouTube Shorts.

Examples

A 16:9 video with a blurred background

A 1920 × 1080 video is scaled down to 1080 × 608 in the center of the 1080 × 1920 frame; above and below, about 656 pixels of blurred background on each side.

Cropping to full screen

In “Fill” mode, the same video is enlarged to 3,413 × 1,920: only the central 1,080 pixels of width remain visible, or 32% of the original picture. Ideal when the subject is in the center.

Frequently asked questions

What size for TikTok, Reels and Shorts?
All three platforms use the vertical 9:16 format, ideally at 1080 × 1920 pixels: that is the format produced by the 1080p export, at 30 frames per second.
What is the maximum length?
The editor exports up to 10 minutes. Check the length accepted by each platform, which changes regularly.
Does the blurred background slow down the export?
Very little: the blur is computed by the graphics card on a scaled-down image. It is turned off automatically when the video already fills the frame.
Does the exported video have a watermark?
No. The exported MP4 file contains no logo or watermark, and the tool is free, with no sign-up.
Are my videos uploaded to a server?
No. Files are read, edited and encoded in your browser, on your device. No video, image or music is uploaded: you can even disconnect once the page has loaded. Closing the tab erases the project.
