About Email Signature Generator

The Email Signature Generator creates a professional HTML email signature from your contact details in seconds. Choose from three templates — Classic, Minimal, or Modern — customize the primary color and font size, toggle individual fields on or off, and upload a profile photo that is embedded directly in the HTML. Copy the result to Gmail, paste it into Outlook, or download a standalone HTML file. Everything runs in your browser; your data never leaves your device.

Use Cases

  • Create a branded signature for your work email in under two minutes
  • Generate consistent signatures for an entire team with the same color scheme
  • Update your signature when you change roles, phone numbers, or social handles
  • Build a minimal signature for text-heavy email clients that strip complex HTML

Tips

  • Use Copy for Gmail for one-click setup in Google Workspace — no HTML editing needed
  • Upload a square photo for best results; the tool crops it to a circle automatically
  • Minimal template renders well in Outlook and older email clients with limited CSS support
  • Toggle the eye icon next to each field to hide it from the signature without deleting the value
