Questions people ask

No. Your browser does all the work on your computer, so your video is never sent anywhere. It works for private and unreleased videos too.
TikTok, Reels, Shorts and Stories: 9:16 at 1080×1920. Instagram feed: 4:5 at 1080×1350 or 1:1 at 1080×1080. YouTube: 16:9 at 1920×1080. Pinterest: 2:3 at 1080×1620. The resizer makes exactly these.
Blur fill keeps the whole video and fills the empty space with a blurred copy of it. Black bars keep the whole video with plain bars. Crop fills the frame and cuts off the edges.
Pick 9:16. For more control over what stays in the crop, use the horizontal to vertical converter, where you can drag the frame.
Recent Chrome, Edge and Safari on a computer, and Chrome on Android. It uses your browser’s own video encoder, so a fast computer makes the video faster. Keep the tab open until it’s done.
Yes. No account, no watermark, and no limit on how many times you use it.
