Frequently Asked Questions

Everything you need to know about compressing your video.

What video formats are supported? expand_more

MP4, MOV, MKV, and WebM. Files up to 2GB are supported. The compressed output is always returned as an MP4 (H.264 video, AAC audio) for broad compatibility.

How much smaller will my video be? expand_more

Most videos shrink by 60 to 75 percent. The exact ratio depends on the input. Smartphone footage and screen recordings tend to compress the most. Already-compressed files compress less.

Will quality be affected? expand_more

Quality loss is generally not visible on typical content (talking heads, screen recordings, tutorials, vlogs). VidClean uses a quality-targeted encoder, not a fixed bitrate, so the picture stays clean even when the file gets much smaller.

Is my video kept private? expand_more

Yes. Files are processed on a private server and automatically deleted 15 minutes after the job finishes. We never view, share, or store your content.

How long does compression take? expand_more

Roughly real-time on the input duration. A one-minute video typically finishes in under a minute. A five-minute video takes a few minutes. Larger files and higher resolutions take proportionally longer.
