These were easy ways to reduce video file size on phones and PC without any app. There was no watermark, but the video did lose significant quality. In my experience, the compression ratio seemed quite good. You can also directly upload files from Google Drive or Dropbox to compress them.
The same was reduced to just about 6 MB after compression. In the screenshot above, you can see that the uploaded video file size was 49 MB. Once the video is processed, you can download it by clicking the Download button.
