How it works
- 01
Add a video
Drop it or choose it. It plays here first, so you can see what you are working on.
- 02
Pick a quality
Good suits almost everything. Drop the resolution too if it is going to a phone.
- 03
Save it
The bar fills and the file downloads. The page shows what it saved.
How a video gets smaller
Two things decide the size: how many pixels each frame holds, and how many bits are spent describing them. Resolution is the first, quality is the second, and dropping either one shrinks the file.
This tool asks for a level of quality and spends whatever it takes to reach it. A still talking head needs very few bits and comes out tiny. A snowstorm needs many and comes out large. The alternative is to fix the bitrate instead. That hits the number you asked for, and lets the picture fall apart on the one clip that needed more.
That is why there is no size promised before you start. The honest answer depends on what is moving in your footage, and you get the real number the moment it finishes.
- Input
- MP4, MOV, MKV, WebM and AVI. One video at a time.
- Output
- H.264 in an MP4, or VP9 in a WebM. Four quality levels.
- Resolution
- Keep the original, or drop to 1080p, 720p, 480p or 360p.
- Sound
- Re-encode it at 128 kbps, leave it untouched, or remove it.
What to pick, and when
Most phone video is 1080p or 4K, and most places it ends up show it far smaller. 720p is plenty for chat, email and a slide. Keep 1080p if it is going on a television or into an edit.
Good quality is the default for a reason. High is for footage you will edit again. Smaller suits email limits. Smallest softens the picture in a way you will see on detail like grass or hair.
H.264 in an MP4 plays on everything, which is what you want if you are sending it to someone. VP9 in a WebM is smaller at the same quality but takes noticeably longer to make, so it suits a file for your own site.
Effort changes only the time it takes, never the quality you asked for. Slow spends longer finding a cheaper way to say the same thing, so the file comes out smaller for the same picture.
