What Is Video Resizing? Resolution vs. File Size Explained
Resizing a video means changing its on-screen width and height (resolution). videoconverter.tokyo also lets you choose how to handle the aspect ratio.
What Does Resizing a Video Mean?
It changes the video frame's width and height (in pixels) to the values you specify — handy for adjusting a video to fit social media or a website.
Resolution vs. File Size
Resolution refers to a video's width and height (how detailed the picture is); file size refers to its data volume (in MB). Lowering resolution tends to reduce file size too.
How to Set Width and Height
Enter the pixel values in the output width/height fields. If you leave one or both blank, the original video's size is used.
Why Keep the Aspect Ratio — Padding vs. Cropping
When the target size has a different aspect ratio than the original, videoconverter.tokyo lets you either add padding to fit it all in, or scale up and crop the edges. It never stretches the picture out of shape.
How to Do This on videoconverter.tokyo
- Select your video file (sign-in required).
- Set the output width/height and choose a resize mode.
- Click "Create Edited Video" and download it once it's done.
