Countdown Generator

Generate an animated countdown GIF for embedding in emails. The server renders a fresh GIF for each HTTP request — how often the image reloads depends on the recipient's email client.

How it works: The <img> tag points to this server. Each time an email client fetches the image URL, the server generates a fresh GIF showing the remaining time at that moment.

Email client caching: Behavior varies. Apple Mail and Outlook typically fetch images fresh on each open. Gmail routes images through Google's caching proxy — the GIF may be cached and not refresh on every open.

After expiry: When the end time passes, the countdown shows 00:00:00 and stays there.
