01Use your Gmail web signature on mobile
Build and save the signature in Gmail on the web first. In the Gmail app, open Menu › Settings › your account. If Mobile signature is empty, the app inserts your web signature, including images and formatting, when you compose.

Open the Gmail app › Menu › Settings
Tap your account
Tap Mobile signature
Enter plain text only
The mobile editor does not support images. Clear this field to inherit the desktop signature instead.
FAQ
Why is my Gmail signature not showing on my phone?+−
You may have a separate Mobile signature that overrides the web version, or the web signature was never saved. Clear Mobile signature to inherit desktop, or set a short text line for mobile only.
Does the Gmail app use my desktop signature?+−
Yes, when Mobile signature is off or empty, Google says the app uses your Gmail web signature with images and formatting.
Can I add a logo to my Gmail app signature?+−
Not in the mobile signature editor, which is text-only. Leave mobile signature empty so the app uses your web signature with a hosted logo.
