Gmail Signature Generator

Create a signature made for Gmail. Copy it from the preview, paste it into your Gmail settings, and see how close it is to the size limit.

Step 1: Enter your details

Type in the boxes below. Your signature appears in Step 2 and updates as you type. Leave a box empty to leave that line out.

Your name and job

Shown in bold at the top of the signature.
Shown under your name.
Shown next to your job title, in your accent color.

How people can contact you

Becomes a tap-to-call link.
A second number, if you have one.
Becomes a link that opens a new email.
With or without https://.
Shown as plain text.

Your photo or company logo (optional)

A web address that starts with https:// and ends in .jpg or .png. A file saved on your computer cannot be used, the picture must already be online.
The picture is resized in your browser and never uploaded. It works for the preview and when you paste into Outlook or Apple Mail. Gmail and many readers block images that are embedded this way, so for the best result host the picture online and use the link above. You can download the resized picture below to host it.

Your social media links (optional)

Paste the link to your profile, or only your username.
Numbers only with the country code. Makes a click-to-chat link.

Extra lines (optional)

Shown in small italic text.
The words on the colored button.
Both the button text and this link are needed for the button to show.
A hosted image shown under the signature, about 360 px wide. Use https://.
Where people go when they click the banner.
Shown in small gray text at the bottom.

Step 2: Your signature (updates as you type)

Choose a layout:

Hi Sam,

Thanks for getting back to me. I will send the updated proposal this afternoon.

Best regards,

Step 3: Fine-tune the design (optional)

Changes here update the signature in Step 2.

Text

Divider line

Photo or logo

Step 4: Add your signature to Gmail

  1. Click Copy signature above.
  2. In Gmail on a computer, click the gear icon and choose See all settings.
  3. On the General tab, scroll to Signature and click Create new. Name it.
  4. Click in the signature box and paste with Ctrl+V (Cmd+V on a Mac).
  5. Under Signature defaults, choose the signature for new emails and for replies and forwards.
  6. Scroll to the bottom and click Save Changes.

Menu names can change a little over time. The Gmail app on a phone has its own plain text signature, so this one shows only in Gmail on a computer and in mobile browsers.

How the signature gets into Gmail

Gmail has no box for HTML code in its signature settings. The signature box is a rich text editor, so you paste the finished signature and not the code. The generator copies it in a form that Gmail keeps: tables, colors, links and your photo stay in place.

The 10,000 character limit

Gmail allows up to 10,000 characters in a signature, and that includes the formatting behind what you see. Above, the meter shows how big your signature is. A normal signature is far below the limit. If you come close, remove the disclaimer, shorten the links or choose the Minimal layout. Gmail can add some markup of its own when you paste, so leave a margin.

If the picture does not show

  • The image must be online, and the link must start with https://. A file on your computer is not enough.
  • Do not use a link to a private page, such as a file in a folder that needs a sign in. The people who read your email cannot open it.
  • If the picture is missing after you paste, click the image icon in the signature box and add it again by its web address.

Common problems

  • The signature does not appear in new emails. Check Signature defaults in the settings and choose your signature there.
  • It sits under the quoted reply. Tick the option to insert the signature before quoted text in replies.
  • It looks different on a phone. The Gmail app uses a separate text signature. Open the message in a browser to see the full version.
  • Dark mode. Use dark text and an accent color that is readable on white and on a dark background, and use the dark preview option to test.

For other programs use the Outlook signature generator or the HTML signature code. The main generator has the same layouts, and the email signature guide covers design rules. Need a smaller picture? Use the image resizer before you host it.

A Gmail signature can have up to 10,000 characters, including the formatting. The meter on this page shows your current size.

Why is my logo not showing in Gmail?
