Whether you're setting one up for the first time or replacing an old one, here's exactly where to click — on desktop and mobile.

Create a signature →Open Gmail in your browser, then click the gear icon in the top right and select See all settings.
Scroll down to the Signature section and click Create new. Give it a name (this is just for your own reference, recipients won't see it).
Signature
Paste your signature into the text box. If you built it with a generator, use Ctrl+V (or Cmd+V on Mac) to paste the formatted HTML directly — don't retype it, or you'll lose the formatting and links.
Scroll further down to Signature defaults and choose whether this signature should appear on new emails, replies, and forwards. Then click Save Changes at the very bottom of the page.
Open the Gmail app, tap the menu icon (three lines) in the top left, then scroll down and tap Settings.
Select the account you want to update, then tap Mobile Signature.
Type or paste your signature into the box, then tap the checkmark or OK to save.
If you manage more than one role, or want a shorter signature for replies, Gmail lets you create several signatures and set different defaults for new emails versus replies and forwards.
Go back to Settings → See all settings → Signature, click Create new again, and repeat the paste-and-save steps above. Then, in Signature defaults, choose a different signature for each context.
Signature looks fine in Gmail but breaks in Outlook: this usually means the signature relies on CSS that Outlook's renderer doesn't support. Stick to table-based HTML layouts rather than flexbox or grid for the widest compatibility.
Logo shows as a broken image: make sure the image is hosted at a public URL (not a local file), and that the link doesn't require login to view.
Signature isn't appearing on replies: double check the Signature defaults dropdown — it's easy to set a signature for new emails but forget to also apply it to replies and forwards.
Build one free — pick a template, fill in your details, and get a Gmail-ready copy button.
Create your signature →Yes — upload your logo to the signature editor, then use Gmail's built-in link tool to wrap it in a clickable link to your website.
Check the Signature defaults section in settings — you may have it set to appear only on new emails, not replies and forwards.
Gmail keeps these separate. Desktop signatures support full HTML formatting; the mobile app signature is plain text only. Most people set a rich signature on desktop and leave the mobile one simple or blank.
In Settings → Signature, select the signature and delete the content, or use the trash icon next to its name to remove it entirely.
