Resize video in your browser

Change the width and height dimensions of a video entirely on your own device. Resizing is useful for meeting an upload size limit, fitting a specific aspect ratio, or matching a required resolution for social media platforms. Your files never leave your device, ensuring total privacy and fast results.

How to use Resize Video

Select a video file to resize.
Enter the target width and height in pixels that you require.
Choose how the frame should fit the new size (Contain, Cover, or Fill).
Click Resize Video and let your device handle the processing.
Download the newly resized video file.

Frequently Asked Questions

What is the difference between contain, cover and fill?: Contain keeps the whole frame visible and adds bars where the aspect ratio does not match. Cover fills the new size completely and crops whatever overflows. Fill stretches the picture, which distorts it unless the original aspect ratio matches the new one.
Does resizing make the file smaller?: Usually yes, provided you are reducing the dimensions. Fewer pixels mean less visual data to encode, so reducing resolution is one of the most effective ways to shrink a video file size.
Why does resizing take some time?: Changing the dimensions of a video requires decoding every single frame, resizing the image data, and re-encoding it back into a compressed format. This is a computationally heavy task that utilizes your device's hardware.
