Stop letting Instagram awkwardly crop your videos. With our AI video resizer, you can easily adapt your content for any format, whether it’s a 9:16 Reel, a 1:1 square post, or a 4:5 vertical feed video.

It handles the technical aspects for you, ensuring your video looks exactly how you intended on every part of the platform. This saves time and removes the guesswork from video formatting.

A common worry when resizing videos is losing clarity and sharpness. Our tool is designed to preserve the quality of your original footage. The AI intelligently resizes the video frame without significant visual degradation, so your high-definition content remains crisp and professional. This process is much more than a simple crop; it ensures that your resized video is clean and clear, avoiding the pixelation that can happen with other online converters. Share your best work without compromising on quality.

Maintain Video Quality, Automatically

Traditional video resizers often just cut off the sides of a wide video to make it vertical, which can ruin a great shot. Our tool uses smart AI to identify the main subject or action in your video. When you resize a video, the AI automatically reframes the shot to keep the most important elements in view. Whether it’s a person talking or a product in motion, the intelligent cropping makes sure the focus of your video is never lost, giving you a perfectly composed shot every time.

AI-Powered Cropping with Smart Focus

Easy to Use: Upload your video, type your command, and download your resized clip. It’s that simple. Get the Right Fit: Create optimized content for Reels, Stories, and posts without any technical expertise.
