Gravatar hash
MD5-hash emails for Gravatar avatar URLs in your browser. Lowercase, trim, skip duplicates. Nothing is uploaded.
Paste emails, then Hash list.
How to use the Gravatar hash
- Paste one email per line.
- Leave lowercase and trim on — Gravatar documents that.
- Copy the 32-character hex. The preview also shows https://www.gravatar.com/avatar/{hash}.
MD5 on purpose
Gravatar still identifies profiles with MD5 of the trimmed lowercase address. That is not SHA-256 and it is not a password hash. Do not reuse this file for Meta or Google audiences. Already-hashed 32-character hex rows pass through.
Nothing is uploaded
MD5 runs in the tab. We do not fetch the avatar image.
Gravatar hash FAQ
Why not SHA-256?
Gravatar’s documented lookup is MD5. Use the SHA-256 hasher for advertising lists.
HTTPS URL?
The preview uses www.gravatar.com. Add query size flags yourself if you need them.
