I use Canva a ton for simple graphic designs. It's great that you can access it wherever there's a browser, use it for (mostly) free, and it's extremely user-friendly. Great product, good to see them doing well!
This is what I like most about Canva too. They are always improving their tool with new UI and features without ever forcing me to buy the "Canva for work". They are also great at accepting feedbacks.
How does it compare with h5mag.com, which is what I currently use to do all this .. ?
