Pexels HD videos are high-definition videos available for free on the Pexels website and app. They[SQ]re royalty-free, meaning you can use them in your projects without needing to pay for a license or attribute the creator (though it[SQ]s always a good idea to credit them if possible). "HD" signifies that the videos are of a high resolution, offering better visual quality than standard definition. The exact resolution available will vary from video to video, but generally implies a resolution suitable for various uses, including online videos, presentations, and even some smaller-scale commercial projects.
