Before you continue

This tool hides content inside GIF files for personal, lawful use.
You're responsible for what you hide and who you share it with.
The finished GIF is created locally in your browser and isn't uploaded anywhere.
Text and images are automatically screened before they can be sealed. Racial slurs and hate speech are blocked. Certain images will get you permanently and immediately banned — no warning, no appeal.
Sealing or sharing unlawful, harmful, or infringing content is never permitted.
We understand that there are extensive security measures for what's supposed to be a fun website to mess around with friends, but my partner and i have to make sure that everyone is protected, especially when we are working with hidden images and texts. We will not tolerate abuse to our fellow humans and will do everything to make sure this site is used for what it's meant to be, a silly secret message site to mess around with friends.
For your recipient to receive the message, send the "sealed" gif to them and direct them to the website.

Tuck a message, an image, or a text file inside a GIF's Comment Extension block. The gif plays exactly the same. What's hidden waits inside it. A fun project to show that positive things can be done with hidden metadata. For your recipient to receive the message, send the "sealed" gif to them and direct them to the website.
