Add an image or logo to a Gmail signature

Use Gmail's image control when you want the Signature editor itself to contain a logo. This differs from EmailSigStudio's construction: its signatures use table-based HTML and inline CSS with zero required images. A logo is optional and can be hotlinked from your own site if you include one.

Insert an image in Gmail

  1. 1Place the cursorIn the web Signature editor, click where the image or logo should appear.
  2. 2Open the image controlClick the Insert image icon in the editor toolbar.
  3. 3Choose and insert the logoChoose an image source Gmail offers, select the logo, and insert it. Keep the image sized for a narrow email layout.
  4. 4Save the image signatureSave Gmail settings and send a test email.

Note: Send a test after adding a logo. Gmail or recipient settings can hide or delay remote images, so check that the logo loads and the surrounding text stays readable.

Change your Gmail signature

Update an existing signature

  1. 1Return to Gmail SettingsOpen Gmail in a desktop browser, click the gear icon, choose See all settings, and stay on the General tab.
  2. 2Open the existing Signature entryScroll to Signature and select the existing signature you want to change.
  3. 3Edit its textClick in the Signature editor and update the text or formatting you want to change.
  4. 4Save the changeScroll to the bottom of the page and click Save Changes.
  5. 5Send a test emailSend yourself a test email and check that the changed Gmail signature appears as expected.

Paste once, then test the result

Do not rebuild a pasted HTML signature with Gmail's formatting buttons. Paste the finished HTML once and leave the structure intact.

If a test email shows no signature, check which surface sent it before changing the signature. A message sent in a browser and one sent from the Gmail app do not use the same signature setting.

The sign-off text belongs in Gmail's existing Signature editor. Follow the web setup steps for browser mail, or use the mobile setup steps for messages sent from the Gmail app.
