Fotor
Fotor is an excellent choice if you're daunted by both Adobe Spark and Canva but still want to design your cards online. The free edition allows you to build designs that are elegant, modern, and well-organized. Although some of the templates are a touch basic, there are enough of well-designed ones to compensate.
The final quality of your cards is excellent, and using stock graphics or uploading your own photos to the site is simple. However, there are minimal editing possibilities, which might be beneficial or detrimental. It simplifies the site for users, but it also restricts alternatives, particularly when compared to competitors. Any of your cards can be downloaded to your computer, stored in the cloud, and exported to a variety of formats, including email and social media. You can decorate each one with stickers, but you won't be able to animate them because there are no options for that.
Another disadvantage is that, while Fotor is free, there are a lot of adverts serving into the page while you're producing your cards, and you're constantly prompted to upgrade to the premium version. The tutorials are located in the settings tab and are quite useful.
