What's a filter?

A filter is a tool in photo and video apps that changes how an image or video looks by adding effects, adjusting colors, or fixing imperfections.

They’re super popular on social media apps like Instagram, Snapchat, and TikTok because they help make content look better. Filters can be simple, like making a photo brighter, or more advanced, like turning your selfie into a cartoon.

For example, you might use a filter to make a sunset look more colorful, or you might apply a beauty filter to smooth your skin and brighten your eyes in a selfie.

Filters make it easy to change how something looks without having to edit every little thing yourself. Some are subtle, while others completely change the original image.

Filters have become so common that many people use them on almost every post to keep a consistent look or style on their social media. They also let users have fun and get creative with effects that can be playful or exaggerated.
