How to Add a Signature in Gmail

Add a signature in Gmail, step by step

1. Open Gmail in a browser and click the gear icon in the top-right corner.
2. In the quick settings panel that slides in, click See all settings at the top.
3. You land on the General tab — the signature settings live here, so don't switch tabs. Scroll down until you reach the Signature section.
4. Click Create new and give the signature a name — "Work", "Personal", whatever will make sense when you have several.
5. In the editor that appears, type your name and details, or paste a signature you copied from our email signature generator. The toolbar above the editor handles bold, colors, links (the chain icon) and images (the picture icon).
6. Just below the editor, open Signature defaults and set both dropdowns — For New Emails Use and On Reply/Forward Use. If you skip the second one, every reply you send goes out unsigned.
7. Scroll to the very bottom and click Save Changes. In current Gmail a Save Changes bar appears at the bottom of the page as soon as you make an edit — Gmail does not save anything on this page by itself, and this is the single most common reason a new signature "doesn't work".
8. Send yourself a test email. Ten seconds, zero surprises.

Using a work or school account? Signature settings can be restricted by your organization's admin. If the section is missing, locked, or Save Changes refuses to work, that's usually why — not you.

How to add an image or logo to your Gmail signature

Gmail signatures aren't limited to text. There are two ways to put an image in, and they behave differently:

• Paste method (fastest). Copy an image anywhere — a handwritten signature PNG, a logo, a photo — click into the signature editor at the spot where you want it, and paste with Ctrl+V (Cmd+V on Mac). Good for quick setups.
• URL method (most reliable). Click the image icon in the editor toolbar, paste the public web address of the image, and click Insert. The image is loaded from that address, which is how companies keep logos working in signatures for years. If you're keeping the signature long-term, host the image somewhere public and use this method.

Gmail has no built-in way to create a signature image — that's what our free signature generator is for: draw it by hand or type it in a script font, download the transparent PNG, and paste it into the editor. Because the background is transparent, it sits on the email like ink, not like a pasted screenshot.

One quirk worth knowing: pasting an image drops it into a text line, and Gmail keeps that line's spacing — which is why pasted images sometimes show a stubborn gap. Giving the image its own line fixes it; inserting by URL usually avoids it entirely.

How to change your signature in Gmail

Same path as adding one: gear icon → See all settings → General → Signature. Your existing signatures are listed; click the one you want to edit and the editor opens with its current content. Make your changes, set the defaults if needed, and click Save Changes at the bottom again.

Your edits apply to emails you compose from then on. Already-sent emails never change.

How to remove or turn off your signature

Two different things, depending on what you want:

• Turn it off temporarily — in Signature defaults, set both dropdowns to No signature and hit Save Changes. Your signature stays saved, ready to switch back on.
• Delete it for good — in the Signature section, click the trash icon next to the signature's name, then Save Changes.

How to use multiple signatures in Gmail

You can keep as many signatures as you like — a formal one for clients, a short one for personal mail, one per role if you juggle hats. Create each with Create new, then pick one as the default under Signature defaults.

To send a single message with a different one: open the compose window and click the pen icon in the bottom toolbar — the one that appears once you have more than one signature. Choose another, and it's swapped for that email only.

How to add a signature in the Gmail app (iPhone & Android)

The mobile app keeps its own signature setting, separate from your desktop one — and it's text-only:

1. Open the Gmail app and tap the menu (☰) → Settings.
2. Tap your account, then find Signature settings.
3. Toggle Mobile Signature on and edit the text. Save with Done or the back arrow.

If you'd rather have your full signature — the one with your logo or handwritten name — appearing when you write from your phone, turn Mobile Signature off. The app then falls back to the signature you set on the web, images included. Menu wording drifts a little between app versions; look for the signature option under your account in Settings.

Gmail signature tips that save you trouble

• Save Changes. Every time. Worth repeating: Gmail's settings page has no autosave.
• Signatures are per-account. If you manage two Google accounts in one browser, set up each one separately.
• Keep images modest. Around 300–400px wide is plenty; oversized images read as attachments and make emails look heavy.
• Test on mobile too. Send one email to a phone you can check — signatures that look fine wide can wrap oddly narrow.
• Short beats complete. Name, title, one way to reach you — everything else is a decision the reader shouldn't have to make.
