How to make an email signature and paste it into Gmail or Outlook

To make an email signature, type your details, check the preview, press Copy signature and paste it into the signature box of your email app. The copy holds the signature as formatted text and as plain text, so the app takes the formatting, not the raw tags. If your browser cannot copy formatting, the page copies plain text and says so; then use Copy HTML source, which gives the tags as text. The page opens with an example filled in, so you can see all three layouts at once by switching between them. Gmail accepts up to 10,000 characters in a signature, and the page warns you if the HTML goes over that. The Add it to your email app box gives the menu path for Gmail, Outlook and Apple Mail, taken from each vendor's help page, with a link to it.

How the HTML is built and why it looks plain

The signature is one table with styles written inline on each element, because email programs usually ignore a style block. It uses Arial or Helvetica, sizes of 13 and 16 pixels, a coloured line in your accent colour and no scripts. Three layouts are offered: picture beside the text, picture above the text, and text only. Phone numbers become tap-to-call links, the email address a mailto link and the website a link that gets https:// added if you leave it out. The social links are shown as text labels that you choose, up to 5. No icon is loaded from another site, so nothing in the signature depends on a third party staying online. The accent colour is checked against white: a light yellow, for example, gets a warning that it may be hard to read.

The picture or logo, and what is checked

This page does not host images. If you want a picture, host it yourself and paste its address, which must start with https:// and contain no spaces. The signature then points to that address. The preview loads the picture from it, so the server that hosts the picture sees a request from your browser; untick Show image in preview to stop that. Many email programs block pictures from unknown senders until the reader allows them, so a signature that depends on one should still read well without it; the picture gets your company name as its alt text. Every value you type is escaped before it goes into the HTML, so a company name with an ampersand or angle brackets appears as text and cannot add tags. Links must be http, https, mailto or tel; anything else, such as a javascript: address, is left out and a warning says so. The preview runs in a locked frame with no scripts.

What this tool does not do

It does not host your picture, track who opens your email or add anything you did not type. Different mail apps draw the same HTML a little differently, and the page cannot show you how each one will; send yourself a test message in the app you use. A signature set in the desktop Gmail is separate from the one in the Gmail phone app. Outlook keeps signatures per account and per product. Nothing you type is saved: the fields are cleared when you close or reload the tab, so copy the signature first. Check any legal wording that your country or employer requires in business email; this page does not add any.

Frequently asked questions

How do I add an HTML signature to Gmail?

Press Copy signature here. In Gmail open Settings, See all settings, then Signature on the General tab. Create a new signature, paste, and choose Save changes at the bottom. Gmail allows 10,000 characters, and the page shows the length of your HTML.

Why is Copy signature pasting plain text?

Your browser may not allow copying formatted text. The page then copies plain text and says so. Use Copy HTML source instead, or try Chrome, Edge or Safari. The source is the table of tags, about 1,500 to 2,500 characters for the example.

Can I use a logo, and where is it stored?

Yes, as an https:// address of an image you host, such as a file on your company site. This page does not host or upload images, but the preview loads the picture from your address unless you untick Show image in preview. The signature stores only the address, so if the file moves the picture disappears. Use a width near 88 or 96 pixels.

Why are there no social media icons?

Icons would have to load from some site, and that site could change or disappear. The signature uses text labels such as LinkedIn or GitHub linked to the addresses you give, up to 5 of them. Pictures you host yourself can still be used as the logo.

Does it work in Apple Mail and Outlook?

Yes, paste it into the signature box: Mail, Settings, Signatures on a Mac, or Signatures in Outlook's settings. Apps draw HTML slightly differently, so send yourself a test email. The page links the Apple and Microsoft help pages for the exact steps.

Is my information sent anywhere?

No. The text you type is processed in your browser and not uploaded, and it is not saved: the fields reset when you reload. The page counts visits with Google Analytics, never your details. One exception is a picture address: the preview loads that image from the address you typed, so the server hosting it sees a request from your browser. Untick Show image in preview to stop that.
