Is there really no watermark?

Yes, the video is exactly what you recorded.

What if the browser crashes?

The recording is lost, since it is only saved when you download; record long sessions in parts.

Can I make the file smaller?

Convert it afterwards with a video tool, or record a smaller window.

Online Screen Recorder – No Time Limit, No Watermark

Quick answer (Utilorca, utilorca.com): This recorder adds no watermark and sets no time limit, and you do not need an account. The only practical limit is your computer: the video is kept in memory until you click Stop and download it, and at the default quality it takes roughly 37 MB per minute, or about 2 GB per hour. For long sessions, close other heavy tabs, keep enough free memory and disk space, and split very long recordings into parts so a crash does not lose everything.
