If you’ve created an email signature in Canva but it looks too big, too small, or blurry in Gmail, you’re not alone! Many Gmail users face this issue when trying to add a professional-looking signature.

The problem often happens because Gmail automatically resizes and compresses images when uploaded to the signature settings. But don’t worry—there’s an easy fix! This guide will show you the correct way to upload, resize, and save your Canva signature so it looks crisp and professional in every email you send.

Why Does My Gmail Signature Look Blurry or Too Big?

Most email clients, including Gmail, don’t allow direct resizing of signature images after they’ve been uploaded. If you try to shrink a large image inside Gmail’s signature editor, the quality can suffer. Instead, you need to upload a large image, manually resize it in a draft email, and then replace the original in your settings.

This method ensures your signature stays clear, properly sized, and professional-looking.

How to Fix Your Blurry Canva Email Signature in Gmail (Step-by-Step)

Step 1: Download Your Canva Signature in the Right Format

✔ Open your Canva design.
✔ Click Share → Download.
✔ Select PNG format for the best quality.
✔ Set the size to at least 1875 x 625 pixels for a clear signature.
✔ Download and save the file to your computer.

Step 2: Upload the Signature to Gmail Settings

1. Open Gmail and click the gear icon (⚙) in the top right.
2. Click See all settings.
3. Scroll down to the Signature section.
4. Click Create new (or edit an existing signature).
5. Click the Insert Image icon and upload your 1875 x 625 PNG signature.
6. Click Save Changes at the bottom (don’t worry if it looks too big).

Step 3: Resize the Signature in a Draft Email

1. Open Gmail and start a new email.
2. Your oversized signature will appear in the body of the email.
3. Click on the signature image, and you’ll see small blue resizing boxes in the corners.
4. Shrink the image down to the correct size using these boxes.

Step 4: Copy the Resized Signature

1. Once the signature looks right, click on the image to select it.
2. Right-click and choose Copy.

Step 5: Replace the Large Signature in Gmail Settings

1. Open Gmail settings again.
2. Scroll to the Signature section.
3. Delete the large image you uploaded earlier.
4. Paste the resized image into the signature box.
5. Click Save Changes at the bottom.

Final Check: Test Your New Signature

✔ Start a new email and check if your signature looks correct.
✔ Send a test email to yourself to ensure it appears properly.
✔ If necessary, repeat the steps to fine-tune the size.

Pro Tips for a Professional Gmail Signature

• Use a PNG file (JPEGs can look blurry).
• Avoid too many images—Gmail may block them.
• Ensure any text in the image is large enough to be readable on mobile.
• Consider adding clickable links (website, social media, etc.).
• Keep in mind that using a signature that is an image means that if your image is blocked, you will have no signature. Check out our post on Canva Email Signatures vs. Other Options: Pros, Cons, and Best Alternatives.
