Question 2

Is this online video compressor free?

Question 3

Is my video private?

Accepted Answer

Question 4

Which video formats can I compress?

Accepted Answer

The tool can read common containers including MP4, MOV, WebM, and MKV when their audio and video codecs are supported by your browser. The downloaded result is an MP4 for broad compatibility.

Question 5

Can I compress a video to a specific file size?

Accepted Answer

The tool estimates a video bitrate from the duration and requested size. Container and codec overhead can vary, so the final file may be slightly above or below the target.

Question 6

Will compression reduce video quality?

Accepted Answer

Compression reduces data, so very strong settings can soften detail. High and Balanced preserve more detail, while Maximum compression prioritizes a smaller file.

Question 7

Which browsers support video compression?

Accepted Answer

Video compression relies on the media codecs built into your browser and device. Current versions of Chrome, Edge, and Safari usually provide the broadest support. If a codec is unavailable, the tool will tell you before compression begins.

Question 8

How does this compare with desktop video compressors?

Accepted Answer

Desktop apps can offer advanced multi-pass encoding and more codec controls. This tool is designed for quick, private compression in your browser with no installation.
