Add a logo to a Gmail signature

To add a logo to a Gmail signature, open Gmail's settings, find the Signature section, create or edit a signature, and use the image button in the signature editor to insert your logo. The file you insert should be a raster image, usually PNG or JPG, exported from your vector logo. Gmail displays the signature logo as an embedded picture, not as editable vector artwork.

The short answer

A Gmail signature can show a logo, but it shows it as an image. Your vector master file, such as an AI, EPS, PDF or SVG source, stays in your design toolkit. For the signature, you export a raster copy of the logo, insert that copy into the signature editor, adjust its display size, and save.

How to insert the logo in Gmail

The general workflow in Gmail on a desktop browser is below. Google changes menu labels and layouts from time to time, so the exact wording on your screen may differ.

• Open Gmail, select the settings (gear) icon, and choose the option to see all settings.
• On the General tab, scroll to the Signature section.
• Create a new signature or select an existing one to edit.
• Place the cursor where the logo should appear, then select the insert image button in the signature editor toolbar.
• Choose the logo from the available sources, such as an upload from your computer, a file in Google Drive, or an image hosted at a web address.
• Select the inserted image to choose a display size, then check the preview.
• Set the signature defaults for new emails and replies if you want it applied automatically.
• Scroll to the bottom of the settings page and save your changes.

After saving, send a test message to yourself and to an account in a different email app. The editor preview does not always match how the logo appears to recipients.

Vector artwork versus the image Gmail displays

This distinction affects how you prepare the logo. Vector artwork is built from paths and shapes that scale without losing sharpness and can be edited in design software. A raster image is a fixed grid of pixels. Email signatures, including Gmail's, rely on raster images. Gmail and many other email clients do not reliably render SVG in messages, so SVG is not a dependable choice for a signature even though it is a vector format.

Once your logo is in the signature, it is a picture of the artwork. Recipients cannot extract editable paths from it, and you cannot edit its shapes inside Gmail. If the logo needs changes, edit the vector master and export a new image.

A file's extension does not show whether it contains true vector paths. An EPS, PDF or even SVG file can contain an embedded raster image instead of editable shapes. If you are working from a supplied logo file, open it in a vector editor and confirm it is built from paths before treating it as your master artwork.

Preparing the logo file from your vector master

• Export as PNG if the logo has flat colors, sharp edges or needs a transparent background. JPG suits photographic content but does not support transparency.
• Export at a higher pixel size than you plan to display. Gmail lets you shrink the displayed size, and the extra pixels help the logo look sharper on high-density screens.
• Keep the file size modest, since large images make messages heavier and slower to load.
• Use a simplified or horizontal version of the logo if the full lockup becomes illegible when small. Fine detail and small text in the mark often disappear at signature size.
• Check transparency against dark backgrounds. A dark logo on a transparent PNG can become hard to see when a recipient uses dark mode. A version with a light outline, or a version on a solid background, can avoid this.

No specific pixel dimensions or file-size limits are confirmed in the material behind this article, so the guidance above is general rather than a precise specification. Test a few export sizes and compare the results in real messages.

Common reasons the logo does not appear

• The image was inserted from Google Drive or a web address that recipients cannot access. Hosted images need to be publicly reachable for others to see them.
• The recipient's email app blocks images until they choose to display them, so the logo may show as a placeholder or attachment.
• The file was SVG or another format the email client does not render.
• The logo was pasted from another document instead of inserted with the image button, which can produce inconsistent results.

Permission to use the logo

Being able to download a logo is not the same as being allowed to modify it or use it. If the logo belongs to your employer or a client, follow their brand guidelines on which version, colors and minimum size to use, and do not recolor, crop or redraw it without permission. Fonts in a logo and the trademark itself may carry separate restrictions. Using another organization's logo in your signature can imply an affiliation or endorsement, so check with the trademark owner first.

What this article could not confirm

No confirmed evidence was available on Gmail's current exact menu labels, image size limits, signature length limits or rendering behavior across specific email apps. The steps and recommendations above reflect general, widely documented practice. Check Gmail's own help pages for current limits, and test your signature in the email apps your recipients actually use.
