You can easily create your own custom Snapchat filter using Canva. Log into Canva and search for “Snapchat Geofilter” or “Custom Filter”. There you'll find pre-made templates that you can edit to suit your event (like birthday, wedding, party). After adding or customizing text, icons, and images, export a transparent PNG or high-resolution image. Then go to the Create Filter section of Snapchat.com, upload, select a date and location, and submit. Canva's design interface is beginner-friendly, so it's perfect for making stylish filters without pro skills.
