Add a picture to your email signature in three steps
You can add a picture to your email signature in Gmail, Outlook, Apple Mail, and most other email programs. The exact steps depend on which email service you use, but the process is similar across all of them: you open your signature settings, insert an image file from your computer, and save the changes. The picture will then appear at the bottom of every email you send.
Most people use a professional headshot, company logo, or small branded image. The picture should be no larger than 200 pixels wide so it doesn't make your signature take up too much space or slow down email delivery. If you don't have an image file yet, you'll need to save one to your computer first — you can download one from the internet, take a screenshot, or use a photo you already have.
Key Takeaways
- Gmail, Outlook, and Apple Mail all let you insert images into your signature through their settings menu.
- Your image file must be saved on your computer or accessible online before you can add it to your signature.
- Keep your signature image under 200 pixels wide so it doesn't slow down email delivery or look oversized.
- Once you save your signature with the image, it will appear automatically on every email you send from that account.
- If the image doesn't show up in emails you receive, the recipient's email program may have blocked images for security reasons.
Add a picture to your Gmail signature
Open Gmail in your web browser and click the gear icon in the top right corner. Select See all settings, then click the Signatures tab. Find the signature you want to edit (or create a new one by typing a name), then click inside the text box where your signature appears.
Click the image icon in the toolbar at the bottom of the signature box — it looks like a small picture frame. A window will open asking you to upload an image. Click Upload and select the image file from your computer. Once the image appears in your signature, you can resize it by clicking and dragging the corner. When you're done, scroll down and click Save Changes.
Gmail will now add this image to the bottom of every email you send. If you have multiple email signatures set up, make sure you're editing the right one — you can set different signatures for different email addresses if you have them.
Add a picture to your Outlook signature
In Outlook on the web, click the gear icon in the top right and select View all Outlook settings. Go to Mail > Compose and reply, then scroll down to the Email signature section. Click inside the text box and position your cursor where you want the image to appear.
Click the image icon in the toolbar (it looks like a small picture). Select Upload from this device and choose your image file. Outlook will insert the image into your signature. You can resize it by clicking and dragging, or right-click on it to adjust properties like width and height. When you're finished, click Save at the bottom of the page.
If you use Outlook as a desktop program on Windows or Mac, the process is slightly different. Open Outlook, go to File > Options (Windows) or Outlook > Preferences (Mac), then select Mail > Signatures. Click in your signature text box, then use the toolbar to insert an image the same way.
Add a picture to your Apple Mail signature
Open Apple Mail and go to Mail > Preferences in the menu bar. Click the Signatures tab, then select the email account and signature you want to edit on the left side. Click in the signature text box and position your cursor where you want the image.
Go to Edit > Attachments > Attach Files and select your image. Apple Mail will insert the image into your signature. Unlike Gmail and Outlook, Apple Mail treats signature images as attachments, so they may appear slightly differently depending on how the recipient's email program displays them. You can resize the image by clicking on it and dragging the corner handles.
Make sure your image file is the right size
Email signatures should be small and professional-looking. Keep your image under 200 pixels wide — this is wide enough to see clearly but small enough that it won't dominate your signature or slow down email delivery. Most email programs will let you resize the image after you insert it by clicking and dragging the corners.
If you're not sure how wide your image is, you can check on Windows by right-clicking the file and selecting Properties, then looking for the dimensions. On Mac, right-click the file and select Get Info. If your image is larger than 200 pixels, you can resize it using a free tool like Pixlr, Canva, or even Windows Paint before you add it to your signature.
File size also matters — keep your image under 50 kilobytes if possible. Large image files can slow down email delivery and may trigger spam filters. Most email programs will compress the image automatically, but starting with a smaller file is better.
Troubleshoot if your signature image doesn't appear
If you've added an image to your signature but it's not showing up in emails you send, the most common reason is that the recipient's email program has blocked images for security. This is a setting on their end, not yours, and there's nothing you can do about it. The image is still there — they just can't see it.
If the image doesn't appear in your own emails when you send them, try these steps: first, make sure the image file still exists on your computer and hasn't been moved or deleted. Second, check that you're looking at the right email account — if you have multiple accounts, each one has its own signature settings. Third, log out of your email and log back in, then send a test email to yourself to see if the image appears.
If you're using Outlook and the image appears in your signature settings but not in actual emails, try removing the image and re-adding it. Sometimes Outlook needs you to re-insert the image for it to send correctly. If the problem persists, try uploading a different image file to see if the issue is with that specific file.
Use an online image instead of uploading a file
Some email programs let you link to an image hosted online instead of uploading a file from your computer. This is useful if you want to update your signature image without changing your email settings — you just replace the image file on the web server, and it updates everywhere automatically.
In Gmail, you can paste the web address of an image directly into your signature. In Outlook on the web, click the image icon and select From a URL instead of uploading. In Apple Mail, this option is not available — you have to upload a file from your computer.
If you use an online image, make sure the web address stays active. If the image is hosted on a free service that deletes old files, your signature image may disappear after a while. Using an image hosted on your company's website or a permanent service like Imgur is more reliable.
Frequently Asked Questions
Can I add multiple pictures to my email signature?
Yes, you can add more than one image to your signature in Gmail, Outlook, and Apple Mail. Just insert each image in the signature text box the same way you would insert one. However, keep your total signature size small — multiple images can make your signature look cluttered and slow down email delivery.
What image file types work in email signatures?
Most email programs support JPG, PNG, and GIF files. These are the most common image formats and work reliably across all email clients. Avoid BMP or TIFF files — some older email programs may not display them correctly.
Will my signature image appear the same way for everyone who receives my email?
Not always. Some email programs display images differently, and some recipients may have image blocking turned on for security reasons. Your image will look best in modern email programs like Gmail, Outlook, and Apple Mail, but may appear differently in older programs or webmail clients.
Can I make my signature image clickable as a link?
In Gmail and Outlook on the web, you can right-click the image after inserting it and select the option to add a link. In Apple Mail, this option is not available through the standard interface. If you need a clickable image, you may need to use a third-party signature tool.
What should I do if my image file is too large to upload?
Resize the image to be smaller in pixels (width and height), or compress the file to reduce its file size. You can use free tools like Pixlr, Canva, or Paint to resize your image. Aim for under 50 kilobytes and under 200 pixels wide for best results.
