Email Signature Generator

Your email signature, done in two minutes. Fill in a short form and six ready-made templates redraw themselves as you type. Pick the one you like, copy it into Gmail, Outlook or Apple Mail. Business or private, logo and photo optional, and everything runs in your browser.

Build an HTML email signature in your browser

A mail footer generator built for people who do not want to learn an email design suite. Fill in your details, watch six signature templates update live, and take the one you like as rich text, a downloaded HTML file, or raw HTML. The output follows the rules email clients actually enforce: table layout, inline styles, web-safe fonts, alt text on images, dark-mode-safe colors. Works for a business account or a private one, and nothing you type or upload ever leaves your browser.

Account type:

Logo (optional)

Hosted images load in Gmail, Outlook and Apple Mail. Classic Outlook on Windows and Thunderbird keep them hidden until the recipient allows images.

Photo (optional)

Hosted images load in Gmail, Outlook and Apple Mail. Classic Outlook on Windows and Thunderbird keep them hidden until the recipient allows images.

Which mode fits: Gmail and Outlook do best with hosted image URLs; Apple Mail and Thunderbird render hosted and embedded alike.

How to use:

            
    
                
  1. Pick Business or Personal at the top; in Personal the company fields are only hidden, and the Show business fields button brings them back
    2. 
                
  2. Fill in your details; everything is optional except your name
    3. 
                
  3. Add a logo, a photo, or both if you want them; they are resized in your browser, never uploaded
    4. 
                
  4. Watch the six templates update and click the one you like
    5. 
                
  5. Copy the signature, download the .html file, or view the raw HTML
    6. 
                
  6. Follow the install steps for your mail client (Gmail, Outlook, Apple Mail) below the generator
    7. 
            

            
Everything runs in your browser: no network calls from the generator, no analytics on your input, nothing stored. The only outside load is a hosted image URL you paste in yourself.

        


        

            
Why use this email signature generator?

            

                

                    
Six templates at once

                    
You choose by eye, not by clicking through a wizard; every template redraws live as you type.

                

                

                    
Rules-compliant output

                    
Table layout, inline CSS, web-safe fonts, alt text, dark-mode-safe colors, so the signature survives real mail clients.

                

                

                    
Business or private

                    
One toggle relabels the form; empty fields simply disappear from the signature.

                

                

                    
Images done right

                    
Point at a hosted image URL for the widest client support, or embed small images right in the HTML when you have nowhere to host them; either way your files are resized in your browser and nothing is uploaded.

                

                

                    
Private by construction

                    
No account, no upload, no server; the page works offline after first load.

                

            

        


        

            
Add the signature to Gmail, Outlook and Apple Mail

            
Webmail editors have no raw-HTML field, so the rendered paste is the way in everywhere except Thunderbird. The download .html file carries these same steps as a comment inside it.

            

                

                    
Gmail

                    
    
                        
  1. Click Copy signature above (it copies as rich text)
    2. 
                        
  2. In Gmail, open Settings (the gear icon) and choose See all settings
    3. 
                        
  3. In the General tab, scroll to Signature and choose Create new
    4. 
                        
  4. Paste the signature into the editor and save changes
    5. 
                    

                    
Gmail strips embedded images on paste; a hosted image URL survives.

  4. For full fidelity, download the .html file and replace the .htm file in %APPDATA%\Microsoft\Signatures\ with it
    5. 
                    

                    
Remote images stay hidden until the recipient chooses to show them, once.

Thunderbird

                    
The one client that takes raw HTML directly: account settings, signature text, tick Use HTML, then paste the raw HTML from the box above, or point it at the downloaded .html file.

                

            

        


        

            
Frequently Asked Questions

            

                
Is my data uploaded anywhere?

                
No. Everything, including image resizing, happens in your browser; no account, no server, nothing stored.

            

            

                
How do I add the signature to Gmail?

                
Copy the signature with the rich copy button, open Gmail Settings, and paste it into the signature box; Gmail has no raw-HTML field, so the rendered paste is the way. Hosted image URLs survive the paste; embedded images would not.

            

            

                
Does it work in Outlook?

                
Yes; classic Outlook desktop is the pickiest client, which is why the output uses tables, inline styles and cell padding instead of margins. Use a hosted image URL: classic Outlook does not render embedded images, and it hides remote ones until the recipient chooses to show them, once.

            

            

                
Should I link or embed my signature images?

                
Link to a hosted image when you can: Gmail strips embedded images and classic Outlook does not render them, while hosted URLs load in Gmail, Outlook and Apple Mail. Classic Outlook on Windows and Thunderbird hide hosted images until the recipient allows them. Apple Mail and Thunderbird render either mode, so embedding is mainly safe there. Images you see in other people's footers are hosted (Gmail re-hosts them) or attached to the mail by the sender app; a base64 image inside pasted HTML is the one kind Gmail strips.

            

            

                
Why does my signature look different after pasting?

                
Mail clients rewrite formatting on paste, worst in classic Outlook and Yahoo; the download .html and raw HTML routes give the most faithful result, and Thunderbird can even take the raw HTML directly.

            

            

                
Will it look right in dark mode?

                
Colors are chosen from a palette that stays readable when a client inverts colors.

            

            

                
Can I use it for a private email address?

                
Yes, switch the toggle to Personal; the company fields hide but stay available through the Show business fields button, and the templates re-render without them.
