Email signature
An email signature generator that survives Outlook
Fill in your details, pick a template and a colour, and walk away with a signature that looks the same in Outlook, Gmail and Apple Mail. With install steps for each one.
Your photo and your contact details never leave your machine: the signature is assembled entirely in your browser.
Why “nothing is uploaded” matters here
An email signature carries, neatly assembled, exactly what a data broker would pay for: name, job title, company, direct line, mobile and email. It is precisely the raw material for a targeted impersonation attempt. Sites that generate signatures typically send all of that to their server “to render the preview”, and many ask for your email address before letting you download. Here there is nowhere to send it: the signature is assembled in your tab and your photo is converted to text without leaving your computer.
How it works, in 3 steps
-
Fill in your details
Name, title, company and whichever numbers you use. Empty fields are simply left out, so fill in only what you want to show. The preview updates as you type.
-
Pick the design
Five templates, your brand colour and a web-safe typeface. Upload your photo and logo, or paste the address where they are already hosted.
-
Copy it and install it
One button to paste straight into Gmail or Apple Mail, another to download the HTML that Outlook imports, and step-by-step instructions for your program.
Which template suits which sector
- Consultancies and law firmsThe classic with a photo: in legal or tax work, putting a face to the name builds trust and the client knows who they are dealing with.
- Real estateThe card: round photo, mobile number front and centre, logo underneath. In this trade the mobile call is the channel, so it should jump out.
- Healthcare and clinicsThe minimal: text only, no photo or logo. Patient email passes through strict filters, and a light signature lands in the inbox more reliably.
- Agencies and creative studiosThe logo on top: the brand leads rather than the person, and the studio's social links sit one click away.
- Technology and engineeringThe compact: one line with the essentials. In long working threads, a six-line signature repeated twenty times is noise, not branding.
- Whole teamsAny of the five, generated in one go from a CSV so all forty people in the company end up with exactly the same signature.
Outlook signature HTML: why almost all of them break
Here is the detail that explains 90% of the trouble: desktop Outlook on Windows does not use a browser engine. It uses Microsoft Word's. And Word, as an HTML renderer, belongs to another era: no flexbox, no grid, no reliable float, external stylesheets ignored, and a good chunk of modern CSS discarded. It makes no difference that your signature looks perfect in Chrome.
That is why most generators fail: they produce browser-oriented HTML, show you a flawless preview on their own site, and the mess only appears when a colleague opens the mail in Outlook. Elements stack, the photo jumps to its own line, the colours vanish.
What Word does respect is the old approach: nested tables and inline styles. No classes, no <style> block, every property written into its tag's style attribute, widths repeated as a width attribute as well as in the style, and mso-line-height-rule:exactly so the leading does not collapse. That is how this generates from the start, not as an afterthought.
A free professional email signature, no watermark, no sign-up
No account, no verification email, and no “created with” line stapled to the bottom of your signature. There is no paid tier hiding the good templates either: all five are here, with your colour and your typeface.
The three export buttons exist because each program wants it a different way. Copy signature puts formatted HTML on the clipboard, which is what Gmail, Apple Mail and Outlook on the web want — you paste straight into the box. Download HTML gives you a file ready for desktop Outlook's signature editor, which works with files. And copy source hands over the raw HTML, for anyone who wants to tweak it or feed it into a corporate signature system.
Images: embedded or hosted
This is the decision that causes the most grief, so it is worth understanding before you choose.
If you upload the file, the image is converted to text and travels inside the signature itself. It depends on no server and cannot break. In exchange: desktop Outlook does not display images in that format, some spam filters treat them with suspicion, and the signature gets heavy — one unoptimised photo turns a 3 KB signature into a 200 KB one, and past 100 KB some servers start clipping the message.
If you paste a public address, the signature weighs the same with images as without, and it displays in every client, Outlook included. The price: the image has to be genuinely reachable from outside — your website, your company server, a public link — and the recipient may have to click “show images” the first time.
Rule of thumb: embedded for yourself, hosted for the team or if anyone uses Outlook. And either way, make sure the signature reads without the images: if the logo fails to load, the email should still say who you are.
That “converted to text” is exactly Base64, and if you want to see how much heavier your signature is about to get before you commit, you can drop the logo in there and it tells you the resulting weight along with the data URL, ready to paste.
Why your brand typeface is not going to happen
Mail clients do not download webfonts. If you set your corporate typeface and the recipient's computer does not have it installed, it gets substituted — and in Outlook the substitute is usually Times New Roman, which will wreck the design more than the right font would have improved it. So only faces that ship with Windows and Mac are offered here. It is a limitation of email itself, not of the tool, and any generator promising otherwise is showing you a preview nobody will see in their inbox.
The whole company on one signature
The second tab solves the problem of forty people running forty different signatures, each with its own font and colour. You upload a CSV with one row per person — columns are matched by name, in English or Spanish — and download a .zip with each person's HTML, all on the same template. A sample CSV is downloadable so you can see the exact shape.
In team mode images must be hosted: embedding forty people's photos would produce an enormous archive and, once again, one invisible in Outlook. You add a column with each photo's address and another with the logo's, which is usually the same for everyone.
The limits, stated before they bite
Social links render as text, not icons: an icon is an image and would drag in every problem above, plus a dependency on a server of ours that could one day fail and leave your signature broken. The photo's rounded corners show in nearly every client but desktop Outlook draws them square — graceful degradation, not a bug. And the formatted copy button needs a recent browser: if yours refuses, the tool says so and offers the source to paste by hand.
Frequently asked questions
Why does my signature look broken in Outlook?
Because desktop Outlook on Windows does not use a browser engine: it uses Microsoft Word's, which does not understand flexbox, grid, reliable float or external stylesheets.
Most generators produce browser-oriented HTML: perfect in their preview, broken on arrival in Outlook. Here it is built from nested tables and inline styles from the start, which is the only thing Word respects.
Why are the images in my signature not showing?
Usually one of three. If you uploaded the file, the image is embedded and desktop Outlook does not display that format. If you pasted an address, it may not be public: an image in your private Drive or on your computer is invisible to everyone else.
And if it is public and correct, many clients block remote images until the recipient clicks “show images”. No tool can prevent that; which is why the signature never relies on images to make sense.
Embedded or hosted images: which should I pick?
Embedded is convenient, depends on no server and works in Gmail and Apple Mail, but desktop Outlook will not show it and it bloats the signature.
Hosted weighs almost nothing and displays everywhere, at the cost of recipients possibly having to allow images. Personal use: embedded. A team, or anyone on Outlook: hosted.
Why can I not use my brand typeface?
Because mail clients do not download webfonts. If the recipient's computer lacks it, it gets substituted, and in Outlook the substitute is usually Times New Roman. So only faces that ship with Windows and Mac are offered. A limitation of email, not of the tool.
How do I generate signatures for the whole team?
On the “Whole team” tab you upload a CSV with one row per person and download a .zip with each signature, all sharing the same template, colour and typeface. Columns are matched by name, in English or Spanish, and a sample CSV is downloadable.
Is my photo uploaded to a server?
No. The photo is read in your browser and converted to text inside the signature itself; it never leaves your machine. Your details are not stored either: no accounts, no database. Load the page, disconnect from the internet and check.
Why are social links text rather than icons?
Because an icon is an image. Embedded it would not show in Outlook, and hosted it would depend on a server of ours that could go down and leave your signature broken. A text link in your brand colour works in every client, always, and weighs nothing.
How heavy should a signature be?
Without embedded images, between 2 and 4 KB. The tool shows the weight at all times and warns above 100 KB, which is where some servers start clipping the message and Gmail shows its “message clipped” notice.
