Is this video converter really free?

Yes. The Darksteady Video Converter is free to use with no sign-up, no watermark and no paid download step.

Are my videos uploaded to a server?

No. Your video is read and converted locally on your device. The file itself is never uploaded to Darksteady or a third-party conversion service.

Which video formats are supported?

You can import common formats including MP4, MOV, WebM, MKV, AVI, MPEG, M4V, 3GP and OGV, then export video as MP4, WebM, MOV or MKV, create a GIF, or extract MP3 or WAV audio.

How can I make a video file smaller?

Choose the Small File preset or reduce resolution, frame rate or visual quality. The smart estimate updates before conversion so you can balance quality and output size.
