Canva is a free website for designing professional quality images and graphics. Canva offers pre-made templates that you can customize, such as posters, social media graphics, infographics, and flyers. When you get to the website it will ask you to sign up with your email. Once you sign in, it will ask you invite friends to see your work but you can skip over that part and get started with the process of creating custom images and graphics. Click on any template, then double-click on any text/image to edit. When you are done creating your masterpiece, you can download it as a jpg, png, or pdf.
This is very popular in our district. Countless social media posts, fliers, and posters are made using this tool. I have used it to create invitations for gatherings on personal use as well.
