Create the signature file first

Open SigVela, type or draw your name, and choose the version that looks best at small email size. For Outlook, a clean transparent PNG is the safest option because Outlook desktop can be strict with HTML.

If you want a full email footer with name, role, and links, use the HTML copy option. Keep the design simple, because Outlook desktop uses Microsoft Word as its rendering engine.

Add it in Outlook for Windows

Go to File, Options, Mail, then Signatures. Create a new signature, insert your downloaded PNG, and add your contact details below it.

Send a test email to yourself before using it with clients. Check that the image is not oversized and that it still looks clear on mobile.

Add it in Outlook on the web

Open Settings, Mail, Compose and reply, then paste your HTML signature or insert the PNG. Save it as your default signature for new messages and replies.

If the pasted HTML loses styling, use the PNG version and keep text details typed directly inside Outlook.

Troubleshooting

If the image appears blurry, export a larger PNG and let Outlook scale it down. If the signature is too tall, reduce the canvas size before downloading.

If recipients see a broken image, avoid remote image URLs and insert the downloaded PNG directly into Outlook.

Common Questions

Should I use PNG or HTML in Outlook?

Use PNG for the handwritten signature mark and simple typed text for contact details. Use HTML only if you need a richer layout and have tested it in Outlook.

Why does Outlook change my signature spacing?

Outlook desktop renders HTML with the Word engine, so CSS support is limited. Simple table-based or image-based signatures are more reliable.
