Please note I am an affiliate for Stencil and I do get compensation for anyone who joins and converts to the paid services. I just use this for all of my images and wanted to spread the word and hopefully show you, readers, the awesome power in Stencil.
There is always a lot of conversations around images and how to get access to a decent selection and that licensed use allows for all types of use. While I thought about Canva I found myself liking Stencil much more.
All the art I use on my sites, when not a personally taken picture, comes from the stock selections available on Stencil. There is also a plugin which allows for direct work in Stencil in WordPress when paired with Shortpixel Image compression can give you amazing on-site image capabilities!
Below are some of my saved items (can keep them forever and reference back) There is an example Pin and it has multiple sizings to help you from any online format (Facebook, YouTube, Pinterest, and others).
I definitely prefer this interface over Canva but I wanted to show where I use for logos, images, headers and in article content.
They have a free option with up to a set amount of images and use per month or paid plans, I would suggest giving the free one a try against Canva or who you use today.
