Authors like @aaliyah.creates have some free use filters w/ credits, & the website cleanpng has a ton of filters you could overlay onto your story. Also if you’re looking to edit like a picture or cover or something like that, websites like BeFunky are the best. If you’re going this route you could also always screenshot the picture with your phone & download an app like VSCO. Lmk if you want links for creators with free use filters!
Of course! Linktree is where most authors/artists post their templates but you can also check the threads on here for people listing their work! Just make sure you read their rules cuz some require credit❤️
