기능
Resize video helps when a website or learning platform only accepts 720p uploads, or when a 4K phone video stutters on an older computer. Pick a preset or enter your own width or height; the aspect ratio is always kept and dimensions are rounded to even numbers for compatibility.
- Presets for 1080p, 720p, 480p and 360p.
- Custom size in pixels: enter just a width or a height.
- Aspect ratio always kept, dimensions rounded to even numbers.
- Audio is preserved and the result is an MP4 file.
- Results get a “-doi-kich-thuoc” suffix, e.g. “intro-doi-kich-thuoc.mp4”.
자주 묻는 질문
Will upscaling a small video to 1080p make it sharper?
No. Upscaling fills in pixels from the existing picture without adding detail, and the file gets bigger.
Why did my width change by one pixel?
Video encoders need even dimensions, so odd values are rounded to the nearest even number.
Does resizing reduce file size?
Lowering the resolution usually cuts the size a lot. If a small file is the main goal, Compress video adds quality levels too.
Should I enter both width and height?
Enter only one value to keep the exact proportions. Leave the other field empty and it is calculated from the video’s ratio.
