Guides
A short read first gets you the right result on the first try.
Video to MP3 Video to MP3: pull the audio out in the right format
Extracting the sound cannot make it better than the original. Your job is to pick the format and bitrate that are just enough for how you will listen or what you will do next.
Compress video Compress video: smaller files that still look good
A video's size is its bitrate multiplied by its length. Lower resolution saves the most, trimming saves the most reliably, and the quality level fine-tunes the rest.

Features
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”.
Frequently asked questions
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.
