Frequently Asked Questions

Is SignOff free?

Yes, completely free with no watermarks, no account, and no usage limits. Everything runs locally in your browser. There are no hidden premium tiers or upgrades.

Does it work with Gmail, Outlook, and Apple Mail?

Yes. The output uses HTML tables with inline CSS, which is the most compatible format across all major email clients including Yahoo Mail and Thunderbird.

How does this compare to WiseStamp?

WiseStamp costs $5.80/month and adds branding to free accounts. SignOff gives you everything — headshot, logo, QR vCard, CTA buttons, 300+ combinations — completely free with zero branding.

How does this compare to HubSpot's signature generator?

HubSpot's generator is free but requires an account. It offers 12 templates. SignOff has 300+ combinations, QR vCards, CTA buttons, and custom colors — all without any sign-up. Create standalone QR codes with our free QR tool too.

Will my signature survive dark mode?

Toggle on "Background Color" to add a white background that keeps your signature readable in dark mode email clients like Gmail and Outlook.

How do I add my signature to Gmail?

Copy your signature, open Gmail Settings, click "See all settings", scroll to Signature, click "Create new", paste, and Save Changes. The built-in Install Guide walks you through each client step-by-step.

Does this collect my personal data?

No. Everything runs 100% client-side in your browser. Your name, email, photos, and all other info stay on your device. Nothing is uploaded to any server. Export settings as JSON to save your work. Try Business CADs for 3D-printable business cards with the same privacy-first approach.
