Quick Answer

Gmail Settings gear → See all settings → General tab → scroll to Signature → click your signature → edit → Save Changes at the bottom.

How to Change Your Gmail Signature (Desktop)

Open Gmail Settings

In Gmail, click the gear icon in the top right corner. Then click See all settings.

Stay on the General Tab

You'll land on the General tab. Scroll down until you see the Signature section.

Click Your Signature to Edit

If you have an existing signature, click on it in the left panel. The content will appear in the editor on the right.

Edit the Content

To make a small change (e.g., update your phone number), click directly in the editor and make your edit.

To replace the entire signature: click inside the editor, press Ctrl+A to select all, then paste your new signature from SignForge with Ctrl+V.

Save Changes

Scroll to the very bottom of the Settings page and click Save Changes. Your updated signature is now live.

How to Change Gmail Signature on iPhone (iOS)

The Gmail app on iPhone has separate signature settings from the desktop. Mobile signatures are plain text only — for a rich HTML signature, use the desktop.

Open the Gmail App

Tap the hamburger menu (three horizontal lines) in the top left corner.

Go to Settings

Scroll to the bottom of the menu and tap Settings.

Select Your Account

Tap the email account whose signature you want to change.

Tap Mobile Signature

Scroll down and tap Mobile Signature.

Edit and Save

Clear the current text and type your new signature. Tap OK to save.

How to Change Gmail Signature on Android

Open Gmail App Settings

Tap the three-line menu (top left), scroll down and tap Settings.

Select Account

Tap the account you want to update.

Find Mobile Signature

Tap Mobile Signature.

Update and Save

Edit your signature and tap OK.

Common Problems When Changing Gmail Signature

Save Changes button is greyed out

You need to actually make a change before the Save button activates. Click anywhere in the signature editor and make a small edit (even add and delete a space) to enable it.

New signature still showing old content

Hard refresh Gmail (Ctrl+Shift+R or Cmd+Shift+R). If using Gmail in multiple tabs, close other tabs — they may be loading a cached version.

Pasted signature shows extra blank lines

This happens with certain copy methods. In SignForge, try clicking the '</>' button to copy the HTML source, then paste it into Gmail's HTML editor (accessible via the three-dot menu in the compose toolbar).

Signature not showing in compose window

Check Settings > General > Signature defaults. Make sure your signature is selected under 'For new emails use'. If it shows '(No signature)', change it to your signature.
