Waiting for content
Free, no sign-up, no watermark. Your code never leaves this browser.
What works in practice
- Keep it around 100 px wide in the signature — bigger looks like an advert.
- PNG with a white background renders most reliably across mail clients.
- Always keep text links too; many clients block images by default.
Common question
Will the code show for everyone?
No. Image blocking is common, so never rely on the code alone — keep your details in text as well.
