Add a logo to your Gmail signature in three steps

Open Gmail, click the gear icon in the top right, select See all settings, then go to the Signature tab. In the signature box, click the image icon (it looks like a small picture frame), choose Upload image, and select your logo file from your computer. Position the logo where you want it in your signature — most people put it at the top or bottom — then click Save Changes at the bottom of the page.

The logo will appear in every email you send from that Gmail account. If you use multiple Gmail accounts, you'll need to add the logo separately to each one. Gmail accepts JPG, PNG, GIF, and WebP files, and the image should be no larger than 25 MB, though smaller files (under 1 MB) load faster in emails.

Key Takeaways

  • You add a logo through Gmail Settings under the Signature tab by clicking the image icon and uploading a file from your computer.
  • The logo appears in every outgoing email and stays in the same position each time you send a message.
  • Gmail accepts JPG, PNG, GIF, and WebP files up to 25 MB, but smaller files load faster for recipients.
  • If you use multiple Gmail accounts, each account needs its own logo added separately in its signature settings.

Where to find the signature settings in Gmail

Start by opening Gmail in your web browser — the mobile app does not have signature editing. Click the gear icon in the top right corner of the screen, next to your profile picture. A dropdown menu will appear with several options. Select See all settings at the bottom of that menu.

Once you're in Settings, look for the Signature tab near the top of the page. It sits between the Labels and Forwarding and POP/IMAP tabs. Click it to open the signature editor where you can add text, images, and formatting to your signature.

How to insert an image into your signature

In the signature text box, click where you want the logo to appear. Then look for the image icon in the toolbar above the text box — it looks like a small picture frame or landscape icon. Click it to open the image upload menu.

Gmail gives you three options: Upload image, Search the web, or Use Google Drive. For a logo file on your computer, choose Upload image. Click Choose file, navigate to your logo on your computer, and select it. Gmail will insert the image into your signature at the cursor position.

Sizing and positioning your logo

After you upload the logo, it may appear larger or smaller than you want. Click the image to select it, then drag the corners to resize it. Most logos in email signatures are between 100 and 200 pixels wide — large enough to see clearly but small enough not to dominate the signature.

You can move the logo by clicking and dragging it to a new position in the signature box. Many people place the logo at the very top, above their name and title. Others put it at the bottom, below contact information. There's no single correct placement — choose what looks balanced and professional for your needs.

File types and size limits Gmail accepts

Gmail accepts four image formats: JPG, PNG, GIF, and WebP. JPG and PNG are the most common. JPG files are smaller and work well for photographs or complex images. PNG files preserve sharp edges and transparency, making them better for logos with clean lines or a transparent background.

The maximum file size is 25 MB, which is large enough for any logo. However, smaller files load faster when recipients open your email. A logo under 1 MB will load almost instantly. If your logo file is larger than 1 MB, you can compress it using free online tools like TinyPNG or Squoosh before uploading it to Gmail.

What happens when you send an email with a logo signature

Once you save your signature with a logo, it will appear automatically at the bottom of every email you send from that Gmail account. You don't have to do anything — the logo is included by default. If you want to send an email without the signature, you can delete it before sending, but it will reappear in the next email.

Recipients see the logo as an embedded image in the email body, not as an attachment. This means it counts toward the email's total size, but it doesn't show up in the attachments section. Some email clients may block images by default for security reasons, so recipients might see a placeholder or broken image icon until they choose to display images.

Using the same logo across multiple Gmail accounts

If you manage more than one Gmail account, each account has its own signature settings. You'll need to add the logo to each account separately. Open each Gmail account, go to Settings, click the Signature tab, and upload the logo following the same steps.

This is useful if you have different roles or purposes for each account — you might use a company logo in your work account and a personal logo or no logo in a personal account. Keep the logo file saved on your computer so you can upload it quickly to each account.

Frequently Asked Questions

Can I add a logo to my Gmail signature on my phone?

No. The Gmail mobile app does not have signature editing features. You must use Gmail in a web browser on a computer to add or edit a logo. Once you've added it, the logo will appear in emails you send from the mobile app, but you cannot change it from your phone.

What if my logo looks blurry or pixelated in emails?

This usually happens when the original image is too small and Gmail stretches it to fit. Start with a logo file that is at least 200 pixels wide. If the file is already large but still looks blurry, the image itself may be low resolution. Try uploading a higher-quality version of your logo, or ask the designer for a version saved at 300 DPI or higher.

Can I make the logo clickable so people can visit my website?

Gmail's signature editor does not allow you to add clickable links directly to images. You can add a separate text link below the logo, or you can use a third-party email signature tool like HubSpot's Email Signature Generator or Newoldstamp, which integrates with Gmail and supports clickable logos. These tools create a signature outside Gmail and insert it into your emails.

Will the logo appear the same way in all email clients?

Most email clients display the logo correctly, but some older clients or strict security settings may block images. Outlook, Apple Mail, and most web-based email services show logos without problems. Always include your name and contact information in text form below the logo so people can reach you even if images don't load.

How do I remove the logo from my signature?

Go to Settings, click the Signature tab, click the logo to select it, and press Delete or Backspace. Then click Save Changes. Your signature will no longer include the logo, but any text in the signature will remain.
