clarkemedia/email-signature-generator

This is a free tool for creating a professional HTML email signature without signing up for any service, paying a fee, or sending your information to a server. You fill in your name, job title, company, phone number, email, website, logo, and social media links using a form, and see a live preview of the signature as you type. There is also a preview mode for both light and dark email themes, so you can check how the signature will look either way. Once you are happy with the result, you copy it either as rich text to paste straight into your email client, or as raw HTML. Any field you leave blank is automatically hidden from the finished signature, so there are no empty placeholders. A built in color picker lets you match an accent color to your brand, and social icons for LinkedIn, Twitter or X, Facebook, Instagram, and GitHub appear only when you provide a link for them. A disclaimer line can be edited or turned off completely. The whole tool is a single HTML file with no build step and no external frameworks, so it can be opened directly in a browser, downloaded to use offline, hosted for free on GitHub Pages, or run through Docker as a small self hosted web server. The README includes step by step setup instructions for Outlook, Gmail, and Apple Mail. This suits freelancers, small business owners, or anyone who wants a clean, branded email signature without handing personal details to a third party service.
