How Do I Filter Free Images on Canva?
Canva is a great tool for non designers that want to create quick graphics that are both nice looking and easy to use. That being said, there are also a few downsides of using Canva - at least if you're on the free tier plan
How Do I Filter Free Images on Canva?
There is no free image filter. Canva has purposely decided to not implement one just to annoy and force you to upgrade. I don't think they will ever implement one if I have to take a guess.
I'm willing to bet they will find out even more ways to annoy free users and make sure you have to scroll for minutes to go trough all the PRO images and illustrations which are arguably nice looking but useless since you're not able to use them.
So, yeah - you either get used to it or spend a few extra bucks per month and get a Canva PRO subscription.
