Reasons for Unable to Attach Files in Gmail

As a convenient communication tool, Gmail allows users to easily attach files, documents, pictures, etc., which makes email an effective way to convey information. By sending attachments through email, you can easily send the files you need to share directly to the recipient, avoiding the limitations that may be encountered in other transmission methods. So, the "cannot attach file in Gmail" issue might be very frustrating!

There could be several reasons why you can't attach files in Gmail. Here are some common issues and solutions:

Solutions for  "Cannot Attach File in Gmail"

Based on the common causes listed above, you can now follow the steps below to resolve the "Can’t attach files in Gmail" issues:

1: Check file size limitations

Ensure that the file you are trying to attach does not exceed Gmail’s attachment size limit: 25MB for standard Gmail account. If it is too large, you can split it into several smaller ones or compress it into a zip file using a professional compression tool.

In addition, you can also use cloud storage like Google Drive to insert large files into your email. Note when you insert files through Google Drive, make sure the file is already in the Google Drive.

2: Clear Browser Cache

If the problem concerns your browser, try clearing your browser cache and cookies. Cookies are automatically generated whenever you visit a website.

Besides, you can also try using a different browser or updating your current one to the latest version.

3: Check Internet Connection

Restart your router or try connecting to a different network to see if the issue persists. Methods for detecting network connections include:

• Physical Check: Ensure both ends of the cable are securely plugged in and check for any damage or looseness.
• Using a Cable Tester: Use a cable tester to check connectivity, ensuring that the indicator lights light up in sequence.
• Observing the Network Icon: Check the network icon in the bottom right corner of the computer to confirm connection status and signal strength.
• Checking Network Connection: Ensure the network cable is properly connected and that Wi-Fi is on and connected to the correct network.
• Checking IP Address Configuration: Confirm that the IP address settings are correct and manually reset them if necessary.

4: Verify Supported File Formats

Check if the file you are trying to attach in your Gmail comes with the file type that is supported by Gmail.  To protect your account, Gmail doesn't allow you to attach certain types of files.

1. Check Filters:

   • Go to Settings (the gear icon) and select See all settings.
   • Click on the Filters and Blocked Addresses tab. Check for any filters that might be affecting your incoming or outgoing emails, especially those that may block attachments. Modify or delete any problematic filters.

When facing problems with attachments in Gmail, account-related issues may be the cause. Sometimes, simply signing out of your Google account and then signing back in can resolve temporary glitches. To do this, click on your profile picture in the top right corner of Gmail, select Sign out, and then log back in.
