Announcement Poster Maker — type the notice, done
Posting a notice in a group chat, a class group or a work channel? Plain text gets buried and skimmed. This scene presets a 1:1 square announcement layout that stands out in chat and as a pinned image: type the notice title and the details, pick a clean theme, and export a 1080×1080 image to post or pin. Runs locally — no login, no watermark.

Why an image instead of plain text
Group chats move fast, and a text notice gets pushed up by the next messages and missed. As an image it stands out and can be pinned long-term as the group's notice, with the key time and place clear at a glance. This scene defaults to a 1:1 square so it isn't cropped in chat or when pinned.
Cover who, what, when, where
A solid notice leaves nothing out: what it is, when, where, and what to bring or do. This scene makes the notice type the headline ("Important Notice"), the subject a subtitle, and the time, place and requirements a line-by-line body. Fill it in this order and nobody has to ask.
Clean beats flashy for a notice
A notice is about legibility, not looks. This scene defaults to a clean ink-on-paper palette — black text on white is the easiest to read and the most official. For a promo or event notice that wants a bit more energy, switch to a colored theme.
Frequently asked questions
What size for a group notice poster?
A 1:1 square (1080×1080) shows complete in the chat stream and when pinned, with no crop. That's the default here.
How much detail fits?
The body wraps and scales, so a few lines is fine; but a notice is best kept short. Put the key time, place and requirements on it and leave the rest for the chat.
Can I use it as a pinned group notice?
Yes. Export the 1080×1080 PNG and set it as your group's notice or pinned image — clean and watermark-free.
