Why use a professional email signature?

Build brand credibility

Frequently asked questions

Is the email signature generator free?

Yes. It works without registration and lets you copy or download the HTML code free of charge.

Are form details sent to a server?

Contact details and generated signature code remain in your browser. Only a logo file selected for upload is sent to PixelShark, where it receives a public, random HTTPS address required to display the image in emails.

Does the signature work in Gmail and Outlook?

The code is designed for popular email clients. Send a test email and verify it on the devices and clients used by your recipients.

Can I use my own logo?

Yes. Enter an existing public image URL or upload a PNG, JPG, GIF or WEBP file. The generator automatically inserts its permanent HTTPS address into the signature code.
