Pixabay is a very popular search engine and app. It is primarily a search engine for its own image database. There are almost one million images on the database and there are paid images too that have higher resolutions than the free images. The search engine tool may be used via a web browser, or you may download and install the image searching tool as an app. Gain access to free photos, images, and art illustrations. The only downside is that the search engine works with tagged keywords that the authors/contributors add, which means some poorly described/tagged images are difficult to find.
