Free email signature generator · No sign-up

An email signature that survives every inbox.

Build a clean, professional signature for Gmail, Outlook and Apple Mail in about two minutes. Most generators produce code that falls apart in Outlook or loses its images on phones; this one is built the reliable way, with simple structure, safe fonts, hosted images and templates that hold together in the strictest corporate mail systems.

Built by Lumira Studio, a content studio in Hertfordshire. It is the signature we use ourselves.

Your details

Identity
Contact
Social profiles (optional)

The right icon is picked automatically.

Images (optional)

A square image at least 150 x 150 pixels looks sharp everywhere. Must be a direct, publicly hosted address ending .png or .jpg. Google Drive and Dropbox share links will not work in email.

That looks like a share link, or the image did not load. Host the file publicly and paste its direct address.

Any company's logo works here. Same rule: a direct, publicly hosted image address.

Style

Text only is the version we use ourselves. Nothing to block, nothing to break, safe for the strictest corporate mail systems and CRM editors.

Social icons match the six preset colours. With a custom colour, icons use ink black so they stay crisp in every inbox.

Following up from this morning

Dark mode shows how most mail apps lighten your text automatically. Images and most accent colours stay as they are, though Gmail may lighten very dark accents too.

Matching reply signature

Good practice: the full signature on first emails, this short version on replies and forwards. Gmail and Outlook both let you set the two separately.

Email it to yourself

You will receive the signature ready to copy, plus a link that reopens this tool with your details already filled in. We use your details only to build that email and link.

Set up your whole team

Fill in the shared details (company, website, logo, colours, template), then copy a link that opens this tool ready-made. Each person adds only their own name and contact details. No accounts, no subscription.

Installing it (this is where most signatures break)

Most "broken" signatures were simply pasted in the wrong place. Follow the steps for your mail app and it will behave.

Gmail
  1. Click Copy signature above.
  2. In Gmail, open Settings → See all settings → General.
  3. Scroll to Signature, create a new one, and paste straight into the box (Ctrl+V or Cmd+V).
  4. Set it as your default for new emails, add the reply version for replies if you like, then Save changes at the bottom.
Outlook (new Outlook and Outlook on the web)
  1. Click Copy signature above.
  2. In Outlook, open Settings → Account → Signatures.
  3. Create a new signature and paste into the editor.
  4. Choose it for new messages, and the reply version for replies and forwards, then save.
Outlook (classic desktop)
  1. Click Copy signature above.
  2. Go to File → Options → Mail → Signatures.
  3. Create a new signature and paste into the editing area.
  4. Assign it to your account for new messages and replies, then OK.

Classic Outlook renders email with the engine from Microsoft Word, which is why this tool avoids anything Word cannot draw. The Download file button gives you a copy to keep on file too.

Apple Mail
  1. Click Copy signature above.
  2. Open Mail → Settings → Signatures.
  3. Create a signature for your account, untick "Always match my default message font", and paste.
  4. Drag it onto your account and close settings.
iPhone and iPad Mail
  1. Use Email it to yourself above, and open that email on your phone.
  2. Press and hold on the signature, select it all, and copy.
  3. Open Settings → Apps → Mail → Signature and paste.

iOS may simplify some formatting; the Text only template survives best there.

Questions people actually ask

Short, honest answers about email signatures, from a studio that sends a lot of email.

Why do email signatures break in Outlook?

Classic Outlook for Windows draws emails with the engine from Microsoft Word, which ignores most modern web styling. Signatures built with fancy layout code collapse there. This tool only generates simple table-based code with all styling written inline, which is the one structure that engine has always drawn correctly.

Should my signature be one big image instead?

No. Image signatures cannot be clicked link by link, they disappear entirely when a recipient's mail app blocks images, screen readers cannot read them, and they often arrive as an attachment. A proper text-and-tables signature with a few small hosted images is more reliable in every way.

What size should my photo and logo be?

Photo: square, at least 150 x 150 pixels; it displays at 72 pixels, so that size keeps it sharp on high-resolution screens. Logo: around 300 pixels wide; it displays at about 150. Banners: 1000 x 200 pixels, displayed at half that. Always upload images at roughly twice their display size.

What happens to my signature in dark mode?

Mail apps lighten dark text automatically and leave images alone. This tool uses near-black rather than pure black text, which converts cleanly, and its social icons sit on small coloured squares so they stay visible on any background. Use the Dark mode preview button to see the effect before you install.

Why do I have to paste an image address rather than upload a file?

Email clients only reliably show images that live at a public web address; images embedded inside the signature code get stripped by Gmail and most corporate systems. So the honest approach is a hosted address. If your company has a website, your web person can host the file in a minute. Sharing links from Google Drive or Dropbox will not work, and the tool warns you if it spots one.

Is there a size limit I should worry about?

Gmail allows 10,000 characters of signature code. This tool shows a live count under the buttons, and its output typically uses well under half the limit. Keep banners to one and the count stays low.

How do I set up a whole team with matching signatures?

Fill in the shared details once (company, website, logo, colour, template), click Copy team link, and send that link to your colleagues. It opens this page with everything pre-filled except the personal fields. Paid tools charge for exactly this; here it is free because the link itself carries the settings.

Is this really free? What do you collect?

Really free, no account, and your details stay in your own browser. A small "Signature by Lumira Studio" credit is included by default, and one tick box removes it - nothing is forced on you. The one exception on data: the optional "Email it to yourself" button sends that one email and keeps a record that you requested it. We are Lumira Studio, a video production studio in Hertfordshire; this tool is our way of being useful to people we may never meet.

Before you go

If you ever need the video side of it.

We built this because we send a lot of email and wanted a signature that behaved itself. Video is the part we do for a living: we plan one filming session with a client and turn it into a couple of months of content, video and photography together. If that would be useful to you, we would be glad to talk it through.
