Pexels.com is the world’s first inclusive free stock photo & video library. You can use the photos and videos available, anywhere – in your brochures, handouts, documents, websites, presentations, blogs – just anywhere you wish to use them. All photos and videos on Pexels are free to use.
Attribution to the original photographer / videographer are not required, although such attributions would be appreciated for obvious reasons. You can modify the photos as you may like. Just be creative and create a work of art – there are no restrictions to the modifications either!
You may use the photos for commercial use too. What is not allowed is to publish pics of identifiable people in a bad light or in a way that is offensive. You may not sell unaltered copies of the pics or videos, without modifying them first.
A very useful site to embellish your creativity, one pic at a time!
