Email signature generator
Type your details, copy, paste into Gmail, Outlook or Apple Mail. No sign-up, no credit line.
Live preview
An example. Your own signature replaces it as you type.
Some mail apps in dark mode invert a message's colours. This shows the full inversion, the harshest case; pictures are left as they are, as those apps do. Check the accent and your logo still read.
HTML source
Layout and style
Your details stay on this device. The signature is built inside this page and saved only in this browser's local storage. Nothing you type is sent anywhere; the one outside address the preview loads is the picture address you type, so you can see it. A share link carries your details after the #, which browsers never send to a server, but anyone you give the link to can read them.
How to make an email signature
- Type your details. Only the fields you fill in appear. Phone numbers become tap-to-call
tel:links, the e-mail amailto:link, and a website typed asexample.combecomeshttps://example.com. - Add a logo or photo by pasting the web address of a picture that is already online, if you want one.
- Pick a layout, an accent colour, a font and a size. Check the dark-mode preview.
- Click Copy signature and paste it into your mail app's signature box, using the steps for your app below. Use Copy HTML instead for apps or tools that ask for HTML source.
Why this signature survives pasting
Mail apps are not web browsers. The signature editors in Gmail and Outlook throw away <style> blocks and class names, and classic Outlook for Windows draws messages with Microsoft Word's engine, which ignores flexbox, grid and positioning. So the HTML made here uses only what they keep: nested tables for the layout, every style written directly on the element that needs it, pixel font sizes, and fonts from the short list most computers and phones have (Arial, Verdana, Tahoma, Trebuchet MS, Georgia, Times New Roman, Courier New), each with a fallback. Every link is absolute (https://, mailto: or tel:), because a relative link means nothing inside an e-mail. Everything you type is escaped, so a < or & in a company name shows as itself rather than breaking the HTML.
A worked example: a side-by-side signature with a logo, four contact lines (phone, e-mail, website, address), one profile link and a one-line disclaimer comes to about 3,600 characters of HTML, well under Gmail's 10,000-character limit. A long legal disclaimer is what usually pushes a signature over; the page counts the characters and warns you past 10,000.
Pasting it into your mail app
Each block below follows the vendor's own help page, linked with the date we read it. Where we add a step of our own, it says so.
Gmail (computer)
- Click Copy signature on this page.
- Open Gmail. At the top right, click Settings, then See all settings.
- In the Signature section, click into the box and paste (Ctrl+V, or ⌘+V on a Mac).
- At the bottom of the page, click Save Changes.
Known limit (Google): up to 10,000 characters per signature, and an image counts toward it.

New Outlook for Windows
- Click Copy signature on this page.
- In Outlook, select Settings, then Accounts > Signatures. With several accounts, pick the one to use.
- Select Add signature and give it a name.
- Paste into the editing box below the name. Use the checkboxes to add it to new messages and to replies and forwards, then select Save.
Known limit (Microsoft): if you also use Outlook on the web with a Microsoft account, you need to create the signature in both.

Classic Outlook for Windows
- Click Copy signature on this page.
- In Outlook, open a new e-mail. On the Message menu, select Signature > Signatures.
- Under Select signature to edit, choose New and type a name.
- Paste into the Edit signature box. Under Choose default signature, pick it for New messages and Replies/forwards, then choose OK.
Known limit (Microsoft): these signatures are stored on the computer where you made them; they may not appear when you use Outlook on another device. Outlook also does not add the new signature to the message you opened in step 2.

Outlook on the web and Outlook.com

Apple Mail (Mac)
- Click Copy signature on this page.
- In Mail, choose Mail > Settings, then click Signatures.
- In the left column, select the account. Click + below the middle column and type a name.
- Paste into the preview in the right column (Apple: “Click Edit in the menu bar to paste text”).
Known limit (Apple): a signature made while All Signatures is selected must be dragged onto an account before you can use it.
Our tip, not Apple's: untick Always match my default message font in the same window, or Mail replaces the signature's font with your message font.

What it cannot do
- It cannot host your logo or photo. A signature picture must already be online at a public https address, such as your website; this page only links to it. Pictures from a private cloud folder or a link that opens a viewer page will not show.
- It cannot set the signature inside your mail account for you. You paste it, using the steps above; no page can reach into Gmail or Outlook settings without your password, and this one never asks for it.
- Mail apps can still restyle or change it. Each app's known limit is listed with its steps above. Some apps also block outside pictures until the reader allows them, and some phone apps ignore rounded corners, so a round photo may show square.
- The dark-mode preview is one case. Apps handle dark mode differently; the preview shows a full colour inversion, not any one app's exact rendering.
- Profile links are text, not icons, for the hosting reason above.
- Saved means this browser. Your signatures are kept in this browser's storage on this device, not in an account; another browser or device will not see them.
Questions
How do I add this signature to Gmail?
Click Copy signature. In Gmail on a computer, click Settings > See all settings, click into the box in the Signature section and paste, then click Save Changes at the bottom. Google allows 10,000 characters; the page shows how long yours is.
Why does my logo not show up?
Each recipient's mail app fetches the picture from its web address, so the address must open the image file itself, publicly, over https. Put the logo on your website and use its direct address (it usually ends in .png or .jpg). A PNG about twice the width shown, for example 144 pixels for a 72-pixel slot, stays sharp on high-resolution screens.
Why do signatures from other generators break when pasted?
Signature editors drop style sheets, class names and modern layout such as flexbox. A signature built from tables with every style written on the element itself keeps its look, which is how this one is built.
Do I need to give my e-mail address or sign up?
No. Nothing stands in front of the copy button, and no credit line is added to your signature. Your details are saved only in this browser; Clear all saved signatures removes them in one tap.
Want your handwritten name in the signature too? Make a handwritten signature picture, put the PNG online, and paste its address in the picture field.
