Common questions
Is my video uploaded anywhere?
No. Resizing happens inside your browser using your device's own video encoder. Your video is never sent to a server.
How do I make a video fit TikTok or Reels?
Choose Social, then Vertical 9:16. Pick Add black bars to keep the whole picture, or Crop to fill to fill the screen and trim the sides.
Will a smaller resolution make the file smaller?
Usually, yes. For the smallest file, Compress Video lets you pick a target size in MB as well.
Is Resize Video free?
Yes, completely free, with no sign-up and no watermark.
