How do I change my email signature in Gmail?

On the web, click the gear icon, choose 'See all settings', stay on the General tab, scroll to the Signature section, click your signature, edit it, then click 'Save Changes' at the bottom. The change is live immediately.

How do I change my Gmail signature on the iPhone app?

The Gmail iOS app uses a separate, plain-text 'Mobile Signature'. Tap the hamburger menu, then Settings, choose your account, tap 'Signature settings', turn on 'Mobile Signature', edit the text, and tap Save. It does not sync with your desktop HTML signature.

How do I change my Gmail signature on Android?

Open the Gmail app, tap the three-line menu, tap Settings, select your account, tap 'Mobile Signature', edit the text, and tap OK. Like iOS, the Android app supports plain text only and is stored separately from the web signature.

How do I change the email footer in Gmail?

The 'email footer' in Gmail is the signature. Personal Gmail accounts have one signature block per account, edited in Settings > General > Signature. If you use Google Workspace, your admin may add an organisation-wide footer server-side that you cannot edit from your own settings.

How do I add an image or logo when changing my Gmail signature?

While editing the signature in Settings > General, place your cursor where you want the image, click the image icon in the formatting toolbar, and either upload a file or paste a public HTTPS URL (Web Address). Resize by clicking the image and choosing Small, Medium, Large, or Original, then Save Changes.

Why won't my Gmail signature changes save?

The 'Save Changes' button only activates after an actual edit, and it sits at the very bottom of the settings page. Make a small change, scroll all the way down, and click 'Save Changes'. If the new signature still shows old content, hard refresh Gmail with Ctrl+Shift+R (Cmd+Shift+R on Mac).

How to Change Your Gmail Signature in 2026

Changing your Gmail signature takes under two minutes. The catch most people hit: Gmail keeps three separate signatures — one for the web, one for the iPhone app, and one for the Android app — and the mobile ones don't sync with the desktop one. This guide covers all three, plus how to change your email footer, swap in a new image or logo, and fix changes that won't save.

Quick Answer

Gmail Settings gear → See all settings → General tab → scroll to Signature → click your signature → edit → Save Changes at the bottom. On the iPhone or Android app, it's a separate Mobile Signature under Settings → your account.

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 or job title), 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 Your Gmail Signature on iPhone (Gmail App)

The Gmail app on iPhone has its own signature, separate from desktop. It's plain text only — no images, links, or formatting. For a rich HTML signature with a logo, set it up on desktop instead (emails you send from the app still carry the mobile signature, not the desktop one).

Open the Gmail App Menu

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 Signature Settings

Tap Signature settings, then make sure Mobile Signature is toggled on.

Edit and Save

Clear the current text and type your new signature, then tap Save (or back out — it saves automatically).

How to Change Your Gmail Signature on Android

The Android Gmail app also stores a plain-text Mobile Signature per account, independent of both desktop and iOS.

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. The change applies to new emails sent from that account on this device.

How to Change Your Email Footer in Gmail

What people call an “email footer” in Gmail is the signature — the block at the bottom of every email. To change it, follow the desktop steps above. Two things worth knowing:

•Different footers for new emails vs. replies. Under Signature defaults, you can assign one signature for “For new emails use” and a shorter one (or none) for “On reply/forward use” to keep long threads clean.
•Google Workspace footers. If your account is managed by an organisation, an admin may append a company-wide footer server-side. It appears after your personal signature and you can't edit it from Gmail settings — ask your IT admin.

How to Add or Change an Image or Logo

You can add a logo or photo to your signature directly in the desktop editor. (Images aren't supported in the iPhone or Android app signatures.)

Open the Signature Editor

Go to Settings → See all settings → General and scroll to your signature.

Insert the Image

Place your cursor where the logo should go, then click the image icon in the formatting toolbar. Upload a file, pick one from Google Drive, or paste a public Web Address (URL).

Resize It

Click the inserted image and choose Small, Medium, Large, or Original. For a logo, Medium (around 100–200 px wide) usually looks right.

Link and Save

Optionally select the image and click the link icon to point it at your website, then Save Changes.

If the logo shows for you but appears broken to recipients, the image URL probably isn't publicly reachable. See adding a logo to your Gmail signature and fixing signature images that don't show for hosting fixes.

Common Problems When Changing Your Gmail Signature

Save Changes button is greyed out

You need to actually make a change before the Save button activates, and it lives at the very bottom of the page. Click anywhere in the signature editor and make a small edit (even add and delete a space) to enable it, then scroll all the way down.

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.

Mobile signature didn't change after editing desktop

Expected. The iPhone and Android apps keep their own plain-text Mobile Signature, separate from the web one. Change it inside the app (see the iPhone and Android steps above).

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 signature editor.

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.

Frequently Asked Questions

Does changing my Gmail signature on desktop change it on my phone?

No. Gmail stores three separate signatures: the web/desktop signature and a plain-text Mobile Signature in each of the iPhone and Android apps. Changing one does not change the others — you have to update each surface you use.

Can I have a different signature for replies?

Yes. In Settings > General > Signature > Signature defaults, set one signature for 'For new emails use' and a different one (or '(No signature)') for 'On reply/forward use'.

How do I change the email footer added by my company?

If your account is a Google Workspace account, a company-wide footer may be appended server-side by your administrator. You can't edit or remove it from your own Gmail settings — contact your IT admin.

Why does my signature look fine on desktop but plain on my phone?

The mobile apps only support plain text, so images and HTML formatting from your desktop signature won't appear in the app's Mobile Signature. Keep a simple text version for mobile, or send from desktop when you need the full HTML signature.
