Why resize?
- 4K phone videos are huge; 1080p looks the same on most screens.
- Some websites, projectors and older TVs need 720p or 1080p.
- Smaller resolutions make editing and sharing faster.
Aspect ratio is kept
Only the height is set; the width is calculated so nothing is stretched. Vertical videos are resized by their width instead, so a 1080p vertical video becomes 1080×1920.
Good to know
Scaling uses a bicubic filter and keeps the aspect ratio. Landscape videos are resized by height and portrait videos by width, so a "1080p" video is always 1080 pixels on its short side.

Frequently asked questions
Can I make a video bigger?
Yes, but upscaling cannot add detail; the video gets bigger without looking sharper.
How much does the Resize Video cost?
Nothing. It is free with no registration, no watermark and no limit on how many files you convert.
Are my files safe?
Yes. Files are converted locally in your browser and are never uploaded. When you close the page, nothing is left behind.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern mobile browsers. Short files work best on phones; for long or high-resolution videos a computer is faster.
