How to compress a video

Frequently asked questions
How do I reduce a video’s file size?
Choose a lower quality such as Small (about 1 Mbps) and a lower resolution such as 480p, then start the conversion.
Why does conversion take as long as the video?
The browser re-records the video while it plays, so a one-minute clip takes about a minute. Keep the tab open until it finishes.
Is there a watermark?
No. The converted video has no watermark and no length limit.
Which browsers are supported?
Recent versions of Chrome, Edge and Firefox work best. Safari support depends on its version.
