How It Works

Upload your video

MP4, MOV, MKV, or WebM up to 2GB. Drag and drop or click to browse.

VidClean compresses the video

The video is re-encoded with H.264 at a quality target that significantly reduces file size without visible quality loss on typical content.

Download the smaller MP4

Ready in seconds. Use it for email attachments, Discord, Slack, or upload to social platforms with a tighter file size budget. If you only need the audio track, extract audio from your video instead of compressing the whole file.

Who uses this

Creators sending video over Discord, Slack, or email and bumping into 25MB or 100MB upload limits. People posting to platforms with stricter size budgets. Anyone uploading from mobile data who wants to save bandwidth without dropping resolution. If you only need part of the frame, crop your video first to drop the file size even further before compressing.

Drop your video, get a smaller MP4 back. No editor required.

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.

Is it free, or is there a paid plan? expand_more

Completely free. No account, no signup, no watermark, and no paid tier. Unlike Clideo and VEED, which watermark free exports or cap free uploads, VidClean adds nothing and accepts files up to 2GB.

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.
