Gravatar has quietly powered avatar images across countless forums, comment sections, and user profiles for nearly two decades, but embedding one correctly means hashing an email address with MD5 first — a step that’s easy to get wrong by hand. This tool builds the full, correct Gravatar URL for you, entirely in your browser.
What Is the Gravatar URL Generator?
Enter an email address and instantly get a ready-to-use Gravatar image URL, computed using a self-contained client-side MD5 implementation (since MD5 isn’t available through the browser’s built-in Web Crypto API). Configure the image size, choose a default/fallback image style for users without a registered Gravatar, and set a maximum content rating — with a live preview so you can see exactly what will render.
How to Use It
- Open the tool at /tools/gravatar-url-generator.
- Type the email address you want an avatar URL for.
- Adjust the size, default image style, and max rating as needed.
- Copy the generated URL, or use the live preview to confirm it looks right.
Key Features
- Entirely client-side MD5 hashing — your email address never leaves your browser.
- Configurable size from 1px up to 2048px.
- Multiple default/fallback image styles — mystery person, identicon, monster, wavatar, retro, robohash, blank, or a 404 error.
- Live image preview that updates as you adjust any option.
When to Use This Tool
- Adding a user avatar system to a site or app that falls back to Gravatar when no custom avatar has been uploaded.
- Testing how a specific email’s Gravatar (or fallback style) looks before wiring it into production code.
- Understanding exactly how Gravatar’s URL scheme and email hashing work.
