Where will your avatar glow?

The glow effect is visible on modern phones and laptops with bright screens — iPhones, MacBooks, Samsung Galaxy, and most devices made after 2020. On older screens, it will look like a normal image.

How to Upload Your Glowing Avatar

Instagram

Threads

Threads uses your Instagram profile picture. Update it on Instagram and it syncs automatically.

TikTok

TikTok compresses profile pictures and removes HDR. For the glow effect, use the image in your video content instead — HDR works in TikTok videos.
