Question 1

What does the Video Compressor do?

Accepted Answer

It shrinks MP4/WebM video files by letting you pick a target resolution and quality level, right in your browser.

Question 2

Is my video uploaded to a server to be compressed?

Accepted Answer

No, compression happens entirely client-side in your browser, so your video file isn't sent anywhere.

Question 3

Why does compressing a large video take so long or freeze my browser tab?

Accepted Answer

Since all the processing happens on your device, large or long videos can be memory- and CPU-intensive, and performance depends heavily on your device's specs.

Question 4

Is it free to use?

Accepted Answer

Yes, it's free with no account required.

Question 5

Will compressing my video always reduce the file size significantly?

Accepted Answer

The amount of size reduction depends on the resolution and quality settings you choose and how compressed the original file already was, so results vary by video.
